The data set was acquired in the framework of the CRC 1211 “Earth – Evolution at the dry limit” which aims to study continuous longterm (Quaternary-Miocene) paleoclimatic/environmental records from the hyperarid core of the Atacama desert / N Chile covering the last up to 10 Ma. As part of this project, three clay pans were investigated in the Coastal Cordillera (Huara 20° 4'32.75"S; 69°55'1.46"W; PAG: 21°32'27.39"S; 69°54'47.21"W; Paranal 24°29'20.53"S; 70° 8'54.63"W). The clay pans are located along a latitudinal transect across the hyperarid core of the Atacama from 20° S to 24.5° S. The seismic survey comprised a couple of crossing 2D high-resolution seismic lines per each of the clay pans, acquired with vertical component geophones, Geode recorders and a PEG-40 accelerated weight drop as source.
