Gold From Cemented Gravels
November 2011 by Chris RalphThe truth is that cemented gravels are really not all that complex. There is no mystery of how gold grew there or somehow wormed its way into these solid gravels.
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.
The gravels in contact with the bedrock or false bedrock base are often the richest. The same facts apply to the alluvial paystreaks that are formed on gravel bars; the lowest level of the gold-bearing gravel is normally the richest.
…if you are game for digging in and learning more about the intricate details of how gold deposits form, then let’s jump right in.
Alaska is getting a lot of interest these days, not least because of all the gold prospecting shows on television. Hardly a month seems to pass without some new prospecting show being announced, and a couple of the most popular feature Alaska.
The 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.
Silver Peak is a small mining community in Esmeralda County in west-central Nevada, about 30 miles west of Goldfield. Although it’s fairly remote, it’s been an important mining center since the early days.
In this review of precious and base metal deposits in Arizona, it is apparent that several significant mines and mineral deposits occur in eastern Arizona, and there is considerable potential for new discoveries.
