Flat-Fault Gold
August 2001 by Edgar B. Heylmun, PhD
Gold and other valuable metals are often deposited in breccia and rubble formed by flat or gently-dipping faults.

Flat-faults are especially common in southeast California, southern Arizona, and northern Sonora, Mexico. However, they can be present anywhere that crustal stretching has occurred.Additional articles that might interest you...

The Golden Highway—Tuolumne County
October 2003
Heading north into Tuolumne County on California’s Highway 49—the “Golden Highway”—from Mariposa County, you see few traces of the gold rush days because the largest mining town of the period is now covered by Don Pedro Reservoir.
