Description
Color Isostatic Residual Gravity Anomaly upward
continued 10 km viewed on shaded topography with faults. The
isostatic residual color patterns reveal large scale bulk crustal
density variations that correlate with major topographic and
tectonic terrains. Orange is high gravity and
purple is low. Changes in crustal age, terrain type and
temperature produce most of these anomalies.
The gravity data underlying this image is part of a
compilation of new data sets and two large existing regional
databases reprocessed by
Oppliger,
2002. For a comprehensive discussion on the significance of
isostatic residual anomalies see
