Experimental Methods Major and trace elements, including Sm and Nd concentrations, were determined by ICP-AES and ICP-MS at the Actlabs (Ontario, Canada) on whole-rock powders dissolved through the lithium metaborate and lithium tetraborate fusion method. Nd isotopic compositions were determined by Thermal Ionization Mass Spectrometry at the IGG CNR of Pisa (Italy), using a Finngan MAT 262 multicollector mass-spectrometer running in dynamic mode. Measured 143 Nd/ 144 Nd were normalized to 146 Nd/ 144 Nd = 0.7219. ε Nd notation was calculated using a 147 Sm/ 144 Nd ratio of 0.1976 and a 143 Nd/ 144 Nd ratio of 0.512638 as starting values in the chondritic mantle reference. The Nd model ages relative to a quadratic depleted mantle evolution (T DM ) were calculated following DePaolo et al. (1991). During the collection of the isotopic data, four analyses of the JNdi-1 standard (Tanaka et al., 2000) yielded an average value of 0.512102±0.000010 (±2SD). Data are listed in Table DR1. Petrographical and microstructural investigation were carried out on polished thin sections using optical microscopy and back-scattered electron (BSE) imaging. BSE images were acquired at the Dipartimento di Scienze della Terra of Siena (Italy) using a Philips XL30 scanning electron microscope (SEM), operating at an accelerating voltage of 20 kv. Electron microprobe (EMP) analyses of detrital white micas were performed at the Dipartimento di Scienze della Terra of Milano (Italy), by a JEOL 8200 Super Probe, operating at an accelerating voltage of 15 kv, sample current of 5 na and using a beam of 5 µm. Natural standards were used for calibration. The full set of data is available as supplementary material (Table DR2). Sample preparation and 40 Ar 39 Ar analyses were also completed at IGG CNR, using different laser extraction techniques, namely: (1) single-grain total fusion analysis of detrital white micas (20 to 35 flakes; grain size of 180 250µm), separated through standard separation techniques and careful handpicking under a stereomicroscope; (2) insitu analysis on rock chips ~9.0 mm in diameter, drilled from double-polished thick sections (~300 µm thick), previously investigated by BSE imaging; (3) step-heating analysis of a few (4 6) whole-rock grains, handpicked under a stereomicroscope from the 250 360 µm grain size and investigated by SEM prior to 40 Ar 39 Ar analysis. White mica concentrates, rock chips and whole-rock grains were cleaned ultrasonically by alternating methanol and deionized water. Samples were wrapped in aluminium foil and irradiated for 80 h in the core of the TRIGA reactor at the University of Pavia (Italy) along with the dating standard Fish Canyon sanidine (FCs). Single-grain total fusion analyses were completed on individual detrital white mica using a continuous-wave (CW) diode-pumped Nd:YAG (neodymium-doped yttrium aluminium garnet) infrared laser. In situ laser 40 Ar 39 Ar analyses were carried out by either the Nd:YAG infrared laser connected to an external computer-controlled shutter or a pulsed Nd:YAG ultraviolet laser (frequency quadrupled and Q-switched). Single infrared laser shots (lasting 10 ms) of the infrared laser (operating at 12 W) were focused to produce melt pits ~100 µm in diameter. The ultraviolet laser, operating at 20 Hz and 1 mj per pulse, was focused to ~10 µm and repeatedly rastered by a computer-controlled x y stage over areas of ~(100 x 100) µm 2 to produce pits a few tens of micrometers deep. Laser step-heating experiments were performed using the infrared laser beam defocused to a ~2 mm spot size and homogenized by a beam-homogenizer lens which produces a flat power distribution. Steps were carried out at increasing laser power until complete melting occurred. More details on the analytical procedures are also given in Di Vincenzo and Skála (2009). Data corrected for post-irradiation decay, mass discrimination effects, isotope derived from interfering neutron reactions and blank are listed in Tables DR3, DR4 and DR5. Errors on single runs are 2σ analytical uncertainties, including in-run statistics and uncertainties in the discrimination factor, interference corrections and procedural blanks. Uncertainties on total gas ages, on error-weighted mean ages and on single run when used for intersample comparison, also include the

uncertainty in the fluence monitor (2σ internal errors). Ages were calculated using the IUGS recommended constants (Steiger and Jäger, 1977) and an age of 28.03 Ma for FCs (Jourdan and Renne, 2007).
