(A) Pléiades 1B Multi-Spectral Image of the study area. Red dots indicate locations of samples taken for in situ cosmogenic nuclide determinations, and the white dot is the location of the tephra sample. Red lines indicate mapped fault systems (this study), the dashed red line indicates an inferred splay fault. Colour shading provides the relative surface age from geomorphological evidence. No reasonable relative age estimation could be achieved for the green area, based on field and satellite observation. White lines mark major fluvial channels and channel remnants. The areas bound by black dashed lines are used for swath profiles (ArcGIS 10.5.1) of the Adamito fault (B) and for Channel swath profiles (C) of the three major S-N flowing channels. Black dashed lines (1) in the channel profiles (C) mark the elevation of the vertex of the corresponding channels. Blue dashed line (2) marks the confluence area of the two paleo-channel to the east. The red dashed line (3) indicates the elevation of the Río Loa canyon top. Note that these elevations decrease from east to west, here taken as evidence for tectonic tilting of the area and relocation of drainage from east to west.
