This sub-line of research brings together researchers concerned with the study of processes affecting the lithosphere, focussing in phyllosilicates, low-grade metamorphism and hydrothermal ore deposits, using a multidisciplinary approach through qualitative and quantitative study at atomic-scale, in the laboratory and in the field, considering mineralogical, geochemical, geochronological and metalogenetic aspects of rock and sediment samples from different geodynamic contexts. The applications in industry of some special clays and geo-environmental analysis are also considered.

The main aim is to understand the composition, structure and properties of minerals, as well as the reaction mechanisms in surface conditions, so as to evaluate their reactivity and stability, and the effect of environmental parameters on their properties. Experimentally, this research is carried out by studying the kinetics of reactions and the mineral / solution interface reaction, including the effect of organic matter. Crystal morphology and growth patterns are also studied in aqueous and organic media. In addition, the use of computational methods allows an atomistic approach to chemical reactions and an understanding of the structure, morphology
and properties of minerals in surface conditions and others that are not experimentally accessible.

From a methodological viewpoint, our research is based on quantitative crystallographic, mineralogical and textural determination, geochemistry of trace elements in minerals and rocks, complemented by theoretical and experimental studies. These studies involve the extensive use of cutting-edge instrumental techniques such as electron microscopy (SEM, TEM, AEM, AFM, EMPA), spectroscopy (FTIR, ATR-IR) and analytical techniques for major and trace elements (XRF, AAS, ICP-MS). The team includes recognised spanish and international experts in the application of these instrumental techniques to the geological sciences.
