Inspired by a poll, everyone who follows me gets to look at a rock per day for the month of October!
Day 10: Today’s rock is a monzonite. Monzonite is a type of intrusive igneous rock. But the type of rock isn’t as important in this case as where it came from! This rock was picked up from the tailings pile of a gold mined named the Duplex Mine in Searchlight, Nevada. The Duplex Mine created a gold rush that built the town of Searchlight into a town larger than Las Vegas at that time. (LOL, 1500 people in Searchlight vs 800 in Las Vegas in 1910.) Then, the mine played out, and the town dwindled away into a semi-abandoned ghost town surrounded by mine shafts and abandoned claims.
The blue/green in the rock is copper that was mined along with the gold.
