Surface and subsurface geology of the Hontomín structure, Western Pyrenees

A detailed geological study was conducted in the Hontomín area in the western Pyrenees,Northern Spain, focusing on structural characterization by integrating available subsurfacedata with a newly developed surface geological map. It reveals a relatively simple surfacestructure, with the Upper Cretac...
