Rock and Formations of the Mother Lode Gold Belt
October 2015 by Chris RalphThe faulting, folding and shearing that occurred in the Mother Lode belt has created zones of structurally weak rocks or contacts between different types of rock, which has been favorable for the deposition of gold bearing ores.
The steeper the gradient is, the more potential erosive power to move gold and other bedload sediments, and the more power to remove obstacles to flow.
These conditions don’t just apply to Alaska and the Yukon; they apply to western Canada and even to the mountainous western United States.
Has your experience ever led you to wonder why some gold is deposited on bedrock and in crevices, while other gold is not? We’re going take a deeper look at this and see what we can figure it out.
...we will continue our examination of the rich streams and mining districts, and then take a look at some of the big nuggets that have been found here.
In this article, we’re going to take a look at the minerals that contain gold and silver, and how you as a prospector can identify them in the field.
This mine was a real wonder of engineering, and the water supply and drifts had to be carefully managed to keep it in operation. In fact, it didn’t close due to lack of gold, but instead closed with the fall of the Roman Empire.
Q: Are there any mills that handle VMS ore?
