Description: In 2019, as part of the interdisciplinary DFG priority program SPP1803 „EarthShape - Earth Surface Shaping by Biota“, the DeepEarthShape project was launched. The main goal of this German-Chilean research initiative was to gain a broader understanding of the interaction between geological, geochemical and biological processes controlling the weathering in the first tens to hundred metres of the subsurface. The elongated Chilean Coastal Range was selected as the ideal study area to investigate the effects of vegetation, precipitation and erosion on the transformation of intact bedrock into regolith within the so-called critical zone (CZ). This area encompasses several climate zones, from dry to humid, within a similar geological complex. We have carried out a Radio-Magnetotelluric (RMT) survey using a horizontal magnetic dipole (HMD) transmitter to image the electrical resistivity distribution, the lateral extent of the near-surface layers and the CZ at two sites of the DeepEarthShape project – Santa Gracia (shown in this data publication) and Nahuelbuta (https://doi.org/10.5880/GIPP-MT.202003.1).
