Förlagets beskrivning
Excerpt from Geology of the Saltdale Quadrangle, California, And, Mineral Deposits of Saltdale QuadrangleMountains. Elevations range from feet at the dry lake to feet in El Paso Mountains.Formations within the Saltdale quadrangle may be divided into two main groups, a pre - Cretaceous basement complex, and a Cenozoic series of continental sediments and volcanics. The basement complex consists of pre-cambrian Rand schist, pre Cambrian Mesquite schist, the late Paleozoic Garlock series feet of shale, chert, quartzite, limestone, and volcanics), and plutonic intrusive rocks, probably Jurassic, ranging from granite to quartz diorite. The Garlock series, Mesquite schist, and plutonic rocks crop out in El Paso Mountains; but only the Rand schist and plutonic rocks are exposed in the Rand Mountains. The Cenozoic rocks consist of the Goler formation feet of continental sediments, probably Miocene), the Ricardo formation feet of Pliocene to Pleistocene continental sediments, tufi, and lava), and the Black Mountain basalt (100 feet of Pleistocene lava). These three formations crop out in El Paso Mountains, and are separated by unconformities.El Paso Mountains constitute a block uplifted along El Paso fault at its southeastern base, and tilted northwestward. The Mesquite schist and Garlock series strike about N. 20° W. And dip steeply east. Most of the intrusive bodies that crop out in El Paso Mountains likewise follow this trend. The Cenozoic rocks crop out on the northwestern ank of the mountains and dip northwestward toward Indian Wells Valley.The Rand Mountains within Saltdale quadrangle probably constitute a block uplifted along a buried fault at its northwestern base, and tilted gently southeastward. Within the quadrangle, these mountains consist mainly of granitic rocks; but one remnant of Rand schist is exposed in the northeastern portion of the block.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
