Abstract

The Cidade Universitária Armando de Salles Oliveira at Universidade de São Paulo (CUASO – USP/SP) is considered a natural research laboratory in Geosciences. For more than two decades gravity stations were set in the area as part of the training of students and technicians. It formed a set of 787 points distributed in 8 km2. The free-air anomaly map shows a strong correlation with topography, but Bouguer anomaly map does not show correlation with topography and geology. This map enhances an EW gradient through the central part of the area. This was modeled as an almost vertical fault, 090/80 N, with circa 50 m of vertical displacement.
