2 Program functionality «ZONDPGM» is computer program for 2D interpretation of profile data obtained by gravity and magnetic surveys. Friendly interface and ample opportunities for data presentation allows solving assigned problem with maximum efficiency. Handy control system allows user to choose the best from geophysical and geological point of view equation from great number of equivalent solutions. Gravity survey studies gravity anomalies caused by various density inhomogeneities in the medium and excludes earth crust gravity and relief influence by field subtraction and reduction insertion. Magnetic survey is a traditional method of iron-containing objects exploration. It studies magnetic field of objects which contain ferromagnetic minerals. Interconnection between measured at the surface characteristics and magnetic properties of target medium allows assuming presence of causative magnetic bodies. Magnetic survey studies total magnetic field which is comprised of earth crust normal field, anomalous field caused by magnetized bodies, and magnetic field variations mostly related to sun activity. Anomalous field is a useful component connected with studied medium. It can be extracted by taking into account normal field and by measuring magnetic variations in study area. Magnetic susceptibility is set in CGS system (n*10-5 ), density in g/sm 3, measured values in nanotesla or miligal in the program. Selection of medium model is a crucial issue of inversion process. «ZONDPGM» program replaces anomalous bodies by set of polyhedrons that have infinite extension in perpendicular to profile direction. Each polyhedron has its own geometry, magnetic susceptibility, and density, which are defined during inversion. Surface relief is quite important for field data interpretation. It is possible to take relief into account in the program which sometimes considerably improves results. During program development special attention was devoted to a priori information accounting. Considering equivalence of inverse geophysical problems quality of results directly depends on amount of used a priori data. In order to increase interpretation reliability gravity and magnetic surveys should be integrated with other geophysical methods, drilling, and geological investigations. Geophysical and geological interpretation of anomalies needs detailed study of physical properties of rocks and variation trends along the strike and with depth. Program also
3 allows importing and visualizing data using other methods which makes data interpretation process more integrated. «ZONDPGM» is easy-to-use instrument for interactive interpretation of data obtained by gravity and magnetic surveys and can be used on IBM-PC compatible PC with Windows system. System requirements «ZONDPGM» can be installed on PC with OS Windows 98 and higher. Recommended system parameters are processor P IV-2 GHz, memory 512 Mb, screen resolution 1024 X 768, colour mode True colour (screen resolution change is not recommended while working with data). As far as the program is actively using the registry, it is recommended to launch it as administrator (right click on program shortcut run as administrator), when using higher than Windows XP systems. Program installation and deinstallation «ZONDPGM» program is supplied on CD or by internet. Current manual is included in the delivery set. Latest updates of the program can be downloaded from website: To install the program copy it from CD to necessary directory (e.g., Zond). To install updates rewrite previous version of the program with the new one. Secure key SenseLock driver must be installed before starting the program. To do that open SenseLock folder (the driver can be downloaded from CD or website) and run InstWiz3.exe file. After installation of the driver insert key. If everything is all right, a message announcing that the key is detected will appear in the lower system panel. To uninstall the program delete work directory of the program. Program registration For registration click Registration file item of the main menu of the program. When a dialog appears, select registration file name, and save it. Created file is transmitted to specified in the contract address. After that user receives unique password which depends on HDD serial
4 number. Input this password in Registration field. The second option is to use the program with supplied SenseLock key inserted in USB-port while working. Rock density It is essential to know rock density which is the only physical parameter that gravity survey is based on to perform gravity survey and especially to interpret results. Rock density (or volume weight) is defined as its mass per unit volume. Density unit is g/sm 3. Density is usually measured on samples taken from natural exposures, boreholes or mines. The easiest way to measure density is to weight the sample in the air and in water and then calculate density. The most popular and handy device for density measurement is densitometer and it is based on this approach. Densitometer defines density within the accuracy of 0,01 g/sm 3 [Hmelevskoj, 1997]. In order to receive reliable and representative data it is necessary to measure large quantity of samples (up to 50). On the basis of numerous density measurements on samples from the same lithologic sequence variation curve or cross-plot of values versus number of samples characterized by current density is created. Curve maximum corresponds to the most probable density value for current rock. There are gravimetric and other geophysical methods of field and borehole density assessment. Density of rocks and ores depends on chemical-mineral composition, in other words on bulk density of solid particles, porosity, and pore filler composition (water, solutions, oil, gas). Density of volcanic and metamorphic rocks is mostly defined by mineral composition and increases in passing from acidic to base and ultrabasic rocks. Density of sedimentary rocks first of all depends on porosity, water saturation, and in less degree on mineral composition. But it strongly depends on deposits consolidation, their age, and depth of burial (their increase leads to density increase as well). Examples of density are given below [Hmelevskoj, 1997]. Rock Density (g/sm 3 ) Oil 0,8-1,0 Coal 1,0
5 Water 1,1-2 Soil 1,13-2,0 Sand 1,4-2 Clay 2-2,2 Sandstone 1,8-2,8 Limestone 2,3-3,0 Salt 2,1-2,4 Granite 2,4-2,9 Gneiss 2,6-2,9 Gabbro 2,8-3,1 Basalt 2,7-3,3 Peridotite 2,8-3,4 Copper pyrite 4,1-4,3 Magnetite, hematite 4,9-5,2 Density of the upper part of the crust (average) 2,67 Magnetic susceptibility of rocks and ores Magnetic susceptibility is the main magnetic property of rocks which characterizes the degree of magnetization of materials and rocks. It is dimensionless number in SI system. But in practice it is measured in 10-5 SI units. It ranges from 0 to 10 units for different rocks. Minerals and rocks are divided in three groups by magnetic susceptibility: diamagnetic, paramagnetic, and ferromagnetic. Diamagnetic rocks have very low magnetic susceptibility (less than 10-5 SI units) which has negative value (their magnetization is directed against magnetizing field). Many minerals and rocks such as quartz, mine salt, marble, oil, ice, graphite, gold, silver, lead, copper, etc. are diamagnetic [Hmelevskoj, 1997].
6 Paramagnetic rocks have positive magnetic susceptibility with low values. The majority of minerals, sedimentary, metamorphic, and volcanic rocks are paramagnetic. Ferromagnetic minerals (e.g. magnetite, titaniferous magnetite, ilmenite, pyrrhotite) have very large values (up to several millions of 10-5 SI units). Magnetic susceptibility of the majority of rocks depends first of all on the presence and percentage of ferromagnetic minerals in their composition. Table below gives values of some rock-forming minerals and rocks. It can be seen from the table that ferromagnetic minerals are strongly magnetic. Ultrabasic and base rocks are characterized by the highest magnetic susceptibility values among other volcanic rocks, acidic rocks are magnetic and weakly magnetic. Magnetic susceptibility of metamorphic rocks is lower than the one of volcanic rocks. Sedimentary rocks with the exception of some sandstones and clays are almost non-magnetic. Mineral, rock 10-5 (SI units) measurement range average Quartz - 10 Calcite Gypsum - 12 Coal - 25 Sphalerite Hematite Pyrrhotine Ilmenite 5*10 5-5* Magnetite *10 6 Limestone Sandstone Gneiss Granite
7 Diabase Gabbro Basalt Peridotite Sedimentary (average) Metamorphic (average) Acidic volcanic (average) Base volcanic (average) In order to convert values in CGS system which is used in the program magnetic susceptibility in SI units is divided by 4 Magnetic susceptibility of para- and ferromagnetic rocks decrease with rising temperature and almost disappears at Curie temperature which ranges from +400 to +700 С for different minerals. Maximum depth of magnetic survey investigation is approximately km. Temperature is higher than Curie point at great depth and all occurring there rocks become almost non-magnetic. Target geological structures and ores with magnetic susceptibility are embedded by rocks with magnetic susceptibility. This is the reason why similarly to gravity survey redundant or effective magnetic susceptibility is of interest. Value of can vary and be positive or negative. Magnetic anomalies appear due to variation of from zero [Hmelevskoj, 1997]. Creation and opening of data file To start up «ZONDPGM» it is necessary to create data file of certain format which contains information about measurement parameters and observed values. One file usually contains data obtained from one profile. Text data files created in «ZONDPGM» format have «*.PGM» extension. See data file format for details. For correct running of the program data file must not contain: incorrect symbols of records separator (TAB and SPACE use only);
8 absurd data values (for example, negative values of apparent resistivity); desirably, there must be no more than observed data values in one file. Data file format Program presents universal data format which consists of information about coordinates and relative heights of measurement points. All geometric magnitudes used in the program are set in meters. PGM program data format Data text file is divided into three main blocks that contain information about gravity and magnetic measurements as well as profile topography sample_with_combi. Block of gravity data description starts with start_d_grav line. It is followed by lines that contain measurement coordinates and field data. First record is measurement point coordinate (in meters), second record is observed gravity field values (in miligal), and third record is measurement elevation (in meters) position of gravimeter sensor element. If gravimeter elevation relative to earth surface is greater than or equal to zero, then measurement elevation is to be greater than or equal to relief excess in current point (set in the latter block) or equal to zero if topography data is absent. In other words this parameter is specified using the same units as topography sample_aero. In the majority of cases gravimeter elevation is constant and it is easier just to enter its value. In order to do this start block of topography description with the following key # (start_topo#) sample_with_topo. Relief excess relative to earth surface should be entered with minus sign in the third column. Block of gravity data description ends with end_d_grav line. Block of magnetic data description starts with start_d_mag line. It is followed by lines that contain measurement coordinates and field data. First record is measurement point coordinate (in meters), second record is observed magnetic field values (in miligal), and third record is measurement elevation (in meters) position of magnetometer sensor element. If magnetometer elevation relative to earth surface is greater than or equal to zero, then measurement elevation is to be greater than or equal to relief excess in current point (set in the latter block) or equal to zero if topography data is absent. In other words this parameter is specified using the same units as topography. In the majority of cases magnetometer elevation is constant and it is easier just to enter its value. In order to do this start block of topography description with the following key # (start_topo#). Relief excess relative to earth surface should
9 be entered with minus sign in the third column. Block of magnetic data description ends with end_d_mag line. Each described above block can be absent. Block of profile topography data starts with start_topo line. It is followed by lines that contain relief data. First record is point with known relief excess coordinate (in meters), second record is relief excess. Block of profile topography data ends with end_topo line. This block can be absent if there is no relief data. In this case measurement elevations are equal to device elevation. Sample of data file start_d_grav!

27 Work with model Mode Add polygon. Press button in control panel to run it. Left click is used to add new point to polygon. Right click to close polygon (connect start and end point of the polygon). If it is not possible to create local polygon (in other words if there are intersecting borders or other objects in the polygon) the program will not allow user to close polygon. It is preferable to locate points not very close to each other when creating polygons. Mode Delete polygon. Press button in control panel to run it. This mode is used to delete polygons. Right click on the polygon to delete it. Polygon outline turns red when mouse cursor is positioned inside it. Mode Create associated polygon. Press button in control panel to run it. This mode is used to create polygon (additional part of polygon) attached to already existent polygon, model edges or relief, in other words to some cojoint model domain. Cojoint model domain means set of polygons and model edges that have shared borders. Left click is used to add new point to polygon. Right click to close polygon (connect start and end point of the polygon across the border of adjacent domain). Start and end (terminal) point of the polygon should be positioned on external boundary (which turns red when bringing mouse cursor closer) of cojoint domain. If it is not possible to create local polygon (in other words if there are intersecting borders or other objects in the polygon) the program will not allow user to close polygon and will delete created points. It is important to note that polygons attached to left, right, and bottom model edges have infinite extension in these directions (in other words they expand over model edges). Mode Detach polygon. Press button in control panel to run it. This mode is used to detach polygons from set of cojoint polygons and model borders. It should be kept in mind that detached from model borders polygon loses its infinite extension (is limited by model edges then). Right click on polygon to detach it. Polygon outline turns red when mouse cursor is positioned inside it. Then button Move polygon can be used to move detached part of the polygon from the main polygon. Mode Divide polygon. Serves to create two domains inside polygon. Press button in control panel to run it. This mode is used to divide polygon into two new connected polygons. Boundary line is specified using two points on borders or nodes of the necessary polygon. Left click to select first point. Right click to select the second point and divide polygon. If it is not possible to perform this operation (in other words if there are intersecting borders or boundary is
28 located outside the polygon) the program will not allow user to move polygon and will delete created boundary. Polygon borders and points turn red when approaching mouse cursor. Mode Move polygon. Press button in control panel to run it. This mode is used to move unconnected polygon points. If the polygon does not have common points with other polygons or model borders it is wholly moved. Left click to select necessary polygon. Then move unconnected part of the polygon following mouse cursor. Right click to select new position of the polygon. If it is not possible to perform this operation (in other words if there are intersecting borders or polygon is located inside another polygon) the program will not allow user to move polygon and will return it to its initial position. Polygon outline turns red when mouse cursor is positioned inside it. Mode Move cojoint polygons. Press button in control panel to run it. This mode is used to move polygon and all cojoint polygons. Left click to select necessary polygon. Then move cojoint polygons following mouse cursor. Right click to select new position of the polygons. If it is not possible to perform this operation (in other words if there are intersecting borders or polygon is located inside another polygon) the program will not allow user to move polygons and will return them to their initial position. Polygon outline turns red when mouse cursor is positioned inside it. Mode Add point. Press button in control panel to run it. This mode is used to already existent polygon border. Right click on polygon border to add point. Polygon borders turn red when approaching mouse cursor. Mode Delete point. Press button in control panel to run it. This mode is used to delete point of already existent polygon. Right click on point to delete it. The operation can not be performed if it causes the following situations: borders intersect, polygon is located inside another polygon or there are less than three points in one polygon. Polygon points turn red when approaching mouse cursor. Mode Merge points. Press button in control panel to run it. This mode is used to merge two points in one and attach it to another polygon border or model edge. Left click to select first point of merging. Right click to select second point or border and merge points.. If it is not possible to perform this operation (in other words if there are intersecting borders or there are less than three points in one polygon) the program will not allow user to merge points.
