Petrology and Petrography are two intimately related disciplines aimed at the description and the classification of the rocks and at the definition of their genetic processes. These disciplines are based on the use of a great variety of tools, ranging from the very simple hammar and hand lens, to the more comlex polarizig microscope and to extremely sophisticated devices such as electron microprobes, mass spectrometers and laboratory equipment capable of reproducing the physical conditions characterizing the interiors of the Earth. The main goal of the reaserch studies in Petrology and Petrography is to provide an understanding of the causes for the great diversity of the rocks found on the surface (igneous, metamorphic and sedimentary) and to try to obtain some insights on the nature of the rocks and processes which characterize the deepest portions of the Earth that are not accessible to direct observation.
The DiSTAR research group in Petrology and Petrography is involved in numerous research studies dealing mainly with the study of the genesis of igneous (and subordinately metamorphic) rocks occurring in numerus areas all over the world. The main reserach topics are listed below.
