PGE stands for platinum group elements that would be platinum, osmium, iridium, rhodium, etc. And it’s a kind of an interesting history.
Typically you’ll find them along, contacts with calcite, calcium, things like that that are part of that whole hydro-thermal venting process.īut for right now, I just wanted to call your attention to the amount of gold that exists right there in the middle of Georgia. But in reality they originally were horizontal where the gold would settle out on the bottom of those planes.Īlso, a lot of these things had ancient volcanoes running through them and various forms of water or hydro-thermal deposits that would deposit the gold in there as well.
Floods, cut them, and before you know it, these dipping and diving things are all over the place. This forms the plane that things that were deposited on and has gold trapped in it, very important because most everything, sedimentary, even igneous flows will be deposited on the surface of the earth in a horizontal direction generally when it first is deposited, then as uplifting takes place it rocks and tilts these things back and then they get broken up and flooded. So the dip in the strike form, the angles that these planes that were inclined by basically uplifting, inclined into the earth. These are actually sloping diving planes into the earth. Now some of these ores dive on back into these slopes. What’s happened is as it eroded back, it exposed these gold bearing ores for you to find out. Where at one time there were tall mountains. Lots of hills, lots of valleys and canyons, but nothing very tall.Īnd that’s true here. Whenever there’s heavy flooding, there’s a lot of water moving through and it acts like a band-saw and cut things down in the mountains eventually becoming like the east coast where it’s low and hilly. These are often metamorphosed slates, shales, and silt-stones from prior mountain ranges that went through here that have since been eroded by things like the hurricanes that just struck. That you can see by these lines that run across the same kind of general direction. And that’s because on the east coast, compared to the west coast, the terrain is undergoing decay of the original orogenic mountain structures that were here. Notice the very low hilly terrain, not much in the way of terrain that would give us any indication of this amount of gold. Notice the relief compared to what we had last time when we talked about California. So let’s take a closer look at the whole picture zooming in. Virtually nothing to the southern part as it approaches Florida. There is also a chunk over here in South Carolina as well. It falls mostly in this gold line from due west of Atlanta all the way up through into the North Carolina state line. Georgia as a whole has gold, and a fair amount of it historically. But for right now, let’s take a look at Georgia because that’s what we’re focusing on. A gold line continues north on up through North Carolina. And we’re not showing gold in any of these other states, just Georgia in this map. And let’s zero in on exactly what in the world is going on here. It’s important to pay attention to these kinds of things. We’re running right across north of Atlanta, northwest to northeast, in that diagonal line. These are all gold bearing mines or finds that were found in the state of Georgia, but you can see the majority of them are here in the, in the northern section of Georgia.
Atlanta is right here, but you can see right up to the state line here and we have a chunk over in this area as well, but the primary, line of activity, mining activity, goes right through this region. Here comes Georgia.ĭo you see something I see? This pattern running southwest to northeast through Georgia. Today we’re going to talk about gold in Georgia. I’m going to lead you down the road a bit to work on where gold is in different states.
