Gravity Results and Interpretation in Schurz, NV

This document discusses correction methods for gravity data including elevation, latitude, instrument drift, free air, Bouguer slab, inner and outer terrain. Techniques used to calculate simple and complete Bouguer anomalies are explained, with a focus on relative total horizontal fault offset and sediment thicknesses. The text presents possible models for basin thickness and a simple model of right-lateral fault to interpret the observed gravity anomaly.

Presentation Transcript

  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.

  5. Possible models for basin thickness

  6. Possible models for basin thickness

  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
