Description

Raw data (Excel format) of thermogramivetric and visible-infrared (VNIR) data of samples from 4 locations in the Riotinto area (Calanas, El Villar, Quebrantahuesos, Tharsis). The VNIR data are for the bulk rock and for the size fraction less than 2 micro-meters. The data have been used in multiple publications related to: 1) investigation of the acid-alteration processes that took place in the investigated sites. 2) application of the above information to remote-sensing investigation of clays on Mars, especially kaolinite findings. 3) analysis of VNIR spectra and color in mineral mixtures containing iron oxides, sulfates and clays, and the use of such analysis to identify and quantify Fe minerals in mixtures.
