Major and selected trace element chemistry of Holocene gypsum and anhydrite salt deposits in Atacama Desert, northern Chile
- Cosentino, Nicolás J
- Jordan, Teresa E
Elemental chemistry data for calcium sulfate salts of Holocene age in the Atacama Desert of northern Chile are provided. These data complement the Sr isotopic data obtained for the same samples. Gypsum/anhydrite was selected for sampling that occurs as crystals adhering to surfaces whose other sedimentary materials are likely to have been deposited in the last few hundred years. Samples of 28 Holocene surface salt accumulations for locations between 200–2950 m.a.s.l. and between ~19°30' and ~21°30' S are reported. Elemental chemistry data is expressed in millimoles of soluble X element per gram of sample (mmol/g).
