Seismic interpretation of key stratigraphic and structural surfaces, and crustal faults within the Galicia 3-D reflection survey

This repository contains all the seismic interpretations utilized for the analysis in the article "Origin of serpentinization patterns beneath the S-reflector detachment fault in the Galicia margin, offshore Spain". 

The "Surfaces" file contains the CPS-3 shape files of the major stratigraphic and structural surfaces (seafloor, base of post-rift sedimentary strata, base of pre/syn-rift sedimentary strata, base of crystalline basement, S-reflector detachment fault, Moho). The "Faults" file contains the interpretations of the major crustal faults overlying the S-reflector detachment. The "Data" file contains the spatial boundary of where the S-reflector is the crust-mantle boundary, the P-wave velocities of Schuba et al. (2019) and calculated degree of serpentinization (Schuba et al., submitted) based on Christensen's (2004) 200 MPa/200^oC serpentinite compilation study. 

All seismic interpretations were carried out on Petrel^TM versions 2015 and 2017. The seismic reflection volume that was interpreted can be found at https://doi.org/10.1594/IEDA/500151.
