1 GRAVITY RESULTS AND INTERPRETATION SCHURZ, NV BY: DREW JONES AND MARLON RAMOS GPH 492/692, SPRING 2013

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

3 SIMPLE BOUGUER ANOMALY

4 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 45105 7038 8018.5 891.5

5 POSSIBLE MODELS FOR BASIN THICKNESS

6

7 COMPLETE BOUGUER ANOMALY

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

9 COMMENTS, QUESTIONS, CRITICISMS, AND PROVERBIAL REMARKS ARE WELCOME
