The SiliROck lithotheque: Geochemical Data of Scaglia Bianca Chert from Central Italy

The dataset shows part of the chert collection SiliROck, and the geochemical data acquired. It includes 110 chert samples from five different deposits, both primary and secondary, belonging to Scaglia Bianca Fm, located in the Abruzzo (1), Latium (3) and Umbria (1) regions. At least 15 samples per outcrop have been characterized. The database is equipped with: ID_sample: the identification code of the sample, composed by the GPS point name and the ID number of the sample Region: the region where sampling was performed Paleoenvironment: the depositional environment of the rock sample Age: the age of the geological unit according to the geological literature (see relative paper) Deposit: the type of source, whether primary or secondary (see relative paper) Geochemistry: the geochemical data acquired through the pXRF analysis The dataset is accompanied by a photographic archive where a selection of representative photomicrographs is shown. Chert fresh surfaces have been cleaned and immersed in water and photomicrographs have been acquired using a Leica EZ4W stereomicroscope with built-in LED illumination and CMOS camera.
