Results of total soil chemical analyses on bulk sediment samples from the Atacama Desert

This dataset comprises results of total soil chemical analyses of bulk sediment samples sampled along latitudinal and longitudinal transects between 19 - 25°S and 68.5 - 70.5°W (Atacama Desert, Chile). The soil samples consist of poorly cemented thin surface crusts, powdery chuca, and subsurface concretions from the transition to the costra. The analyses include: X-ray diffraction analyses, thermogravimetric analyses (gypsum content), ion concentration data (Na, Ca, K, Mg, Cl, SO4, NO3), organic/inorganic carbon data.
