US Mines listed rhyolite flows

Rhyolitic flows can have high concentrations of fluorine gas dissolved in the lava which allows the rhyolite to become more fluid. Fluorine gas is a key component in the formation of topaz. These mines listed have the potential to have topaz. I collected topaz crystals from a couple rhyolite locations in Colorado and Nevada. Almandine garnets are often found with topaz in rhyolite deposits.
