How Turquoise Forms
Turquoise forms as a secondary mineral by percolation through acidic aqueous solutions where the primary rock is volcanic with high levels of limonite, iron oxide and copper. In other words; water, which has been heated under the earth, rises upward through limonite rock and creates turquoise in the cracks and crevasses of weathered rock. This occurs in arid regions like the American Southwest and the Middle East. As a side note: Turquoise is mined in Arizona, New Mexico, Colorado, Nevada, and California...all over the southwestern US except Utah, which is known for our copper mine! That's okay, though, we have Variscite - and we'll talk about that a little later.
