A new geo-lithological map of Central Europe (Geo-LiM) has been published in Journal of Maps. The paper, produced by CNR-IRPI of Perugia and the Department of Physics and Geology of the University of Perugia, was elaborated taking into account the chemical and mineralogical composition of the outcropping rocks. In particular, metamorphic rocks have been classified according to the chemical composition of protoliths. The map was then used to estimate the atmospheric CO2 consumed by the chemical dissolution of carbonate and silicate rocks. Geo-LiM is available in vector format together with the original maps and the computer codes used to classify the different lithologies (https://zenodo.org/record/3530257). In this way, following the Open Science concept, the product can be replicated or modified by users.
