I see some yellow there !!! I've looked through some books on gold mining and gold ore, don't know if will ever get to search for the raw stuff but am happy with the little bits I do find, its always a good thing finding gold !!
Thanks, I found this out in near Black Point Lava Flow
Anyways back to lava and gold...couple interesting things. At Craters of the moon there are some of the largest and newest lava flows in the country. I was looking very close at the lava ery closely there were rainbows of color, Very similar to Peacock Ore a Copper Ore....it is actually a layer of glass on the lava. On our trip as we passed through areas that I was familiar with, knowing the mining history and know types of deposits in the area it was interesting to relate the proximity of volcanic activity to the deposits. Most volcanos and lava flows are devoid of gold. Though volcanic influence is major it is typically Epithermal influence. Especially in the Western United States. These types of deposits take eons to form into what is mined in our recent history. There is one known place in the world where significant free gold is being deposited associated with an active volcano. And only one more where gold is actually mined in an active geothermal area it is also an Epithermal deposit. Gold in Lava is not an Epithermal deposit. What you see in a lava flow geologically, happened in a hyper micro second of time....flowed and cooled extremely fast. The uniqueness of finding gold in lava is notable.... Gold is deposited in crystals via intrusion. I have a terminated quartz crystal that contains gold..as do others that have posted.I have also heard of geodes that have been cut exposing amazing chevron gold crystals...literally the rarest gold you could ever hope to find.
