All About Garnets
February 2013
I get a lot of questions from prospectors about garnets, their value and what they tell us about the geology of some types of mineral deposits. So I thought it would be a good idea to take a closer look at the lowly garnet and learn a bit more about it.

Flat-Fault Gold
August 2001
Gold and other valuable metals are often deposited in breccia and rubble formed by flat or gently-dipping faults. Such faults are commonly found in areas of crustal stretching caused by the movement of tectonic plates. 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.
