From figuring out where to park to which stores you want to go to, there are lots of advantages to planning your shopping expedition.

The entire amplitude range of the residual gravity anomaly map is less than 0.5 mGal, so a high precision densely-spaced ground gravity survey was required to achieve this resolution. Similar correlations between positive anomalies and the ore zones are observed in the first vertical derivatives of Bouguer gravity and.

Morphological Similarities of the Anomalous Fields The magnetic and gravity anomaly maps (figs. 2 and 3) are broadly similar. On both maps, the anomalous field is low in the southeast and rises to a northeast-trending ridge that transects the central part of the state. This ridge broadens to a triangular shape where the state joins Pennsylvania.
