Geophysical exploration using gravity data

Abstract

The geometry of the northern part of the Vallès fault, between La Garriga and Cànoves i Samalús is deduced from the gravimetric survey of the region. The survey consists of the relative measurement of the vertical gravitational acceleration with a gravimeter. From the readings acquired the residual anomaly is deduced to create a two-dimensional model of the section of the fault, approximating the bodies to different polygons with a characteristic density
