Land areas show gravity anomalies from …Jul 19, 2021 · Regional & Residual Anomalies. A regional anomaly is a gravity anomaly caused by differences in rock density in a deeper area, while a residual anomaly is a gravity anomaly caused by differences in rock density in the shallower area. 1D Fast Fourier Transform is one way to separate these two anomalies from CBA data. Oregon Complete Bouguer Gravity Anomaly Map. The colors on this complete Bouguer gravity anomaly map (Bankey and others, 1995) represent gravity variations resulting from lateral density variations in the Earth.

At these depths, the faults are expected to permeate the Cenozoic and Mesozoic sedimentary sections.

The maps indicate different anomalies reflecting different causative GM bodies of shallow depths. The high-pass gravity map is described by some insignificant elongated anomalies disseminated in the region with amplitude of −11.8 to 16.5 mGal. The gravity anomalies take three main trends which are ENE, WNW, and E-W directions.
