CORRECTION METHODS -Elevation -Lattitude -Instrument Drift -Free Air -Bouguer Slab -Inner and Outer Terrain Used to Calculate Simple and Complete Bouguer Anomalies

SIMPLE BOUGUER ANOMALY

RELATIVE TOTAL HORIZONTAL FAULT OFFSET FROM SEDIMENT THICKNESSES Using relative vertical sediment offset obtained from bouguer slab inversion and simple trigonometry, a rough estimate of total horizontal offset was calculated by assuming a dipping fault plane. Calculated vertical offset = 105 m Some models for fault geometry Dip AngleHorizontal Offset, m

POSSIBLE MODELS FOR BASIN THICKNESS

COMPLETE BOUGUER ANOMALY

WHAT WE THINK IS HAPPENING: A SIMPLE MODEL OF RIGHT- LATERAL FAULT TO EXPLAIN OBSERVED GRAVITY ANOMALY
