Crump Geyser Geothermal Resource Area Geophysical Survey Data

Geophysical survey data supports resource appraisal of the Crump Geyser Known Geothermal Resource Area in Oregon. The dataset includes a gravity map, audiomagnotelluric measurements, and tectonic interpretations compiled by the U.S. Geological Survey. Primary studies and reporting were conducted in 1975.

Use Cases

• Model sediment thickness using gravity anomaly data and the estimated maximum of 820 meters.
• Map fault boundaries and subsurface structures from the gravity map and tectonic map figures.
• Analyze apparent resistivity lows from audiomagnotelluric measurements near Crump Geyser.
• Correlate geophysical anomalies with regional geology units defined by Walker and Repenning (1965).

Strengths

• Includes a published gravity map reflecting fault-bounded sediment structures.
• Data interpretation was presented to a USGS resource committee in 1975.

Limitations

• Audiomagnotelluric measurements lack coverage at the southern gravity low location.
• Gravity data collection was curtailed by harsh weather, potentially creating gaps.
• The report is a preliminary interpretation without detailed resource appraisal discussion.
