Gypsum from soils of chesas, NE Spain
Description
We show data of soils developed on the outcropping gypseous nucleus of the Barbastro-Balaguer anticline, NE Spain. Chesas is the local name for the lands of this outcrop that stands out in the landscape by its whitish tones. The data collected here come from soils of the municipalities —from West to East— of Peraltilla, Almunia de San Juan, San Esteban, Tamarite, Alcampell, Ivars de Noguera, Camarasa, Torá, and Iborra. The analytical methods plus details of the landscape and sampling sites can be found in: (i) the book entitled “Morfología y génesis de suelos sobre yesos” (http://hdl.handle.net/10261/84695), and (ii) the article entitled “Salada Farrachuela, a saline wetland in Tamarite de Litera, Spain” (DOI: 10.29077/bol.114.ce05.herrero). Here we present a compressed zip file with 300 TIFF images corresponding to 150 thin sections of these soils scanned under both plane polarized and crossed polarizers light. Some of the sections, marked L, are of lichens and their gypseous substrate. Most of the sections —with the prevalent size of 13.5 × 5.7 cm— were manufactured by the first author in the Institut National Agronomique de Paris-Grignon under the technical supervision of Mr. Pierre Guilloré, in the context of a scholarship granted by the Government of France for working in the lab of Dr. Nicolas Fédoroff. The surviving thin sections are archived at the EEAD-CSIC in Zaragoza, Spain. Their scans are compiled in the file “Chesas_150thinsections.zip”. Several dozen micrographs of the chesas thin sections appeared in the above mentioned book published in 1991 (http://hdl.handle.net/10261/84695). The file “Chesas_Fig.captions1991-01.xlsx” presents a tentative English translation of the 154 Figure captions for the micrographs and the other figures in the book. The analytical results for the samples having gypsum determinations are listed in the files “ChesasGyps_Peraltilla-Tora-Iborra.xlsx” and “ChesasGyps_Tamarite.xlsx” Documents: Chesas_150thin_sections.zip Chesas_Fig.captions1991-01.xlsx ChesasGyps_Peraltilla-Tora-Iborra.xlsx ChesasGyps_Tamarite.xlsx Funding We acknowledge the grant PID2021-127170OB-I00 funded by MCIN/AEI/10.13039/501100011033 and by “ERDF A way of making Europe”, and the grant TED2021-130303B-I00 funded by MCIN/AEI/10.13039/501100011033 and by the “European Union NextGeneration EU/PRTR”.
