Feldspathic schist of the Moppin Complex, Hopewell Ridge, New Mexico, USA

Summary edit

Description
English: This image shows an outcropping of feldspathic schist of the Moppin Complex on Hopewell Ridge, New Mexico, USA. Most of the Statherian Moppin Complex is amphibolite, a product of metamorphosis of island arc basalt. However, the Moppin Complex is bimodal, with some beds much higher in silica. This rock, also known as leptite, is representative of the high-silica mode of the complex. It may be a metamorphosed ash flow. The Moppin Complex is part of the Yavapai Province, a Precambrian (Statherian) crustal province that reaches from Wyoming to central New Mexico and from Arizona to at least the Midwest. This province is interpreted as a large island arc that accreted to North American 1.7 billion years ago in the Yavapai Orogeny.
