This very much matches my experience at Magma Copper and the ore body mapping of Resolution Copper. For the first third of my life, I looked out at the volcanic plug that is Picket Post Mountain and went to work in a former hydrothermal zone above a porphyry intrusion.

PEX piping so much better than copper.

I already associated copper with white heat anyway

There are many copper deposits in the intermountain west areas of Idaho and Utah in areas that were volcanically active in the past.

The proposed Pebble Mine in Alaska is rich in several metals including copper and is thought to be an ancient volcanic belch that never quite erupted. Now its giving the EPA indigestion.

Ain’t geology grand?

Fine, so we need more volcanos. Let's plunge an asteroid into the middle east or china. That should do it!

Copper for everyone!!!

As I recall, diamond mines are also associated with volcanoes, or at least with magma channels.

It used to be that there was a third thing associated with copper deposits. On the surface above the copper was semiprecious turquoise, and opaque, blue-to-green mineral that is a hydrous phosphate of copper and aluminum.

Is there any link between volcanoes and the formation of petroleum deposits?

Well if you are going to talk dirty we will have to get the kids off the site.

Magma Copper

Didn't that happen in 1215 in England?

Who is worried about sulfur?

We have sulfur coming out of our ears from the enviro-nazi insisting that it has to be removed from diesel oil.
