This monograph presents the data of geological mapping, structural and economic research of an area of about 230 km², in the outskirts of Jacutinga / MG, south of Minas Gerais State and adjacent areas of the northeastern state of São Paulo, in compliance with the discipline of Graduation Course of Geology at the Institute of Geosciences and Exact Sciences. It consists of Socorro-Guaxupé Nappe, developed in response to the collision of cratons Parana and Sao Francisco (630 Ma ago), with mass transit to the east, affected by the coexistence of a system pushes later, with convergence to Northwest, giving rise to the intricate area of interference of the two provinces. Locally there metasedimentary rocks of molasse basin of Proterozoic- Phanerozoic transition called Eleutério; Intrusive, equigranular and porphyroid granits, polyphase, and predominantly granodioritic migmatites Anatexia of structures with different neossomas predominantly granodioritic to granitic in Group Amparo, paragneisses arcosianos, greywacke, aluminous , calc-silicate, mica schists and migmatites of the aluminous migmatites and Itapira Anatexia of multi-phase, with neossomas predominantly granodiorite, with intercalations orthogneissic homogeneous granitic to tonalitic porphyroid composition of the Amparo. We tried to draw a geological map, semi-structural detail of the area in focus, with location of mineral occurrences economically viable operation. Furthermore, this study aims to train students in basic and applied geology, using techniques learned during the undergraduate course.
