Description:
We provide model outputs from "Numerical Modeling of Mantle Flow beneath Madagascar to Constrain Upper Mantle Rheology Beneath Continental Regions" submitted to Journal of Geophysical Research, Solid-Earth. The model outputs are 6 spreadsheets which contain calculated splitting parameters and TI axes or synthetic Lattice Preferred Orientations (LPO) derived from 3 regional mantle flow models in Madagascar: Edge Driven Convection (EDC) model, lithosphere-mantle wind model from Behn et al. (2004), and lithosphere-mantle wind model from Forte et al. (2010):
1. model1_splitting parameters.xlsx: calculated splitting parameters derived from Edge Driven Convection (EDC) at individual stations formatted as: Stations name, longitude [◦], latitude[◦], calculated fast azimuth φcalc[◦], calculated fast azimuth standard deviation [◦], and delay time δt [sec].
2. model2_splitting parameters.xlsx: calculated splitting parameters derived from lithosphere-mantle wind of Behn et al. (2004) at individual stations formatted as: Stations name, longitude [◦], latitude[◦], calculated fast azimuth φcalc[◦], calculated fast azimuth standard deviation [◦], and delay time δt [sec].
3. model3_splitting parameters.xlsx: calculated splitting parameters derived from lithosphere-mantle wind of Forte et al. (2010) at individual stations formatted as: Stations name, longitude [◦], latitude[◦], calculated fast azimuth φcalc[◦], calculated fast azimuth standard deviation [◦], and delay time δt [sec].
4. model1_TI axis.xlsx: calculated EDC-derived TI axes at individual seismic stations and at regular grids of 0.5◦×0.5◦. The file is formatted as longitude [◦], latitude[◦], depth [km], azimuth [◦], and percentage anisotropy [%].
5. "model2_TI axis.xlsx": calculated TI axes derived from lithosphere-mantle wind of Behn et al. (2004) at individual seismic stations and at regular grids of 0.5◦×0.5◦. The file is formatted as longitude [◦], latitude[◦], depth [km], azimuth [◦] , and percentage anisotropy [%].
6. "model3_TI axis.xlsx": calculated TI axes derived from lithosphere-mantle wind of Forte et al. (2010) at individual seismic stations and at regular grids of 0.5◦×0.5◦. The file is formatted as longitude [◦], latitude[◦], depth [km], azimuth [◦], and percentage anisotropy [%].
