Gravity anomaly map.
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.
