Gravity anomaly map
Gravity anomaly map from GRACE. Currently, the static and time-variable Earth's gravity field parameters are being determined using modern satellite missions, such as GOCE, CHAMP, Swarm, GRACE and GRACE-FO. The lowest-degree parameters, including the Earth's oblateness and geocenter motion are best determined from Satellite laser ranging. A series of Bouguer gravity anomaly maps issued on the same sheetlines as the '1:250,000 UTM Series, geological maps of the UK and continental shelf' series and are intended to complement that series. The series covers the whole of the UK and its continental shelf.

Faults usually can be identified through either steep gradients or truncation of trends. Figure 1 contains two Bouguer gravity maps of Southern California, showing the expression of faults. In the left map, locations a and b show strong gradients, which indicate faults. A series of truncated trends (dashed) near location c also indicate faults.The gravity variations studied by GRACE can be used to determine ground water storage on land masses. By comparing current data to an average over time, scientists can generate an anomaly map to see where ground water storage has been depleted or increased.

B5 : Interpretation of gravity data B5.1 Bouguer anomaly maps Once the Free Air and Bouguer corrections have been made, the Bouguer anomaly should contain information about the subsurface density alone. The effect of latitude and elevation should have been removed. A map of the Bouguer anomaly gives a good impression of subsurface density.A gravity anomaly map contains information about rock density, and depth and distribution of anomaly source rocks. Maps can be derived from the original gravity anomaly grid by using mathematical tools to enhance parts of the gravity field. Derivative maps can show, for example, anomalies that have been mathematically filtered May 5, 2013 · Gravity interpretations can be qualitative where the analysis objectives are satisfied by the mere presence or absence of an anomaly. Interpretation also can be highly quantitative with comprehensive modeling of the geometric and physical properties of the anomaly sources. Effective interpretation requires knowledge of the key geological ...

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