Description

Data for Antarctica Lithosphere.

It supplements the following publication:

Li, L.Aitken, A. R. A.Gross, L., & Codd, A. (2025). Resolving mantle composition suggests a warmer East Antarctic mantleJournal of Geophysical Research: Solid Earth130, e2024JB029677. https://doi.org/10.1029/2024JB029677

It contains the result:
1. Estimate Vs to density composition relationship 01_Vs_Conversion.zip

2. Gravity inversion result 02_FEILDS-Antarctica.zip

3. Lithosphere_Model_Geotif.zip from 100 km to 400 km depth slice including density, temeperture, composition, and viscosity

Model extends -3330000 to 3330000 meters, in 10 km resolution. 

4. ANT20_DTE_postden.txt contains ascii format of the model, x (east), y (north), z (depth), vs_initial (from ANT20), T (temperature), rho (density), eta (mantle viscosity), vs_finial (conversion from the estimated Vs to den, composition relationship), Mg# (composition). Only the mantle component of the conversion (temperature, mantle viscosity, and composition is valid, Not the CRUST!!!!)

Projection: WGS 84 / Antarctic Polar Stereographic - EPSG:3031
