The Delamar Mountains are a mountain range in Lincoln County, Nevada, named after Captain Joseph Raphael De Lamar.〔 The range extends for approximately in a NNE–SSW orientation with a width of about . Surrounding ranges include the Burnt Springs Range and the Chief Range to the north, the Clover Mountains and Meadow Valley Mountains to the east and the Sheep Range and South Pahroc Range on the west. The Delamar Valley lies to the west, the Kane Springs Valley to the east and the Coyote Springs Valley lies to the south of the range.〔〔''Clover Mts., Nevada–Utah,'' 30x60 Minute Topographic Quadrangle, USGS, 1978〕 U.S. Route 93 traverses the north end of the range between Crystal Springs and Caliente. The elevation of the route reaches 6243 feet at Oak Springs Summit pass. Nevada State Route 317 follows Rainbow Canyon south along the northeast margin of the range between Caliente and Elgin.〔〔 The range's crest forms part of the Great Basin Divide between the Meadow Watershed and the Dry Lake Watershed, which includes Delamar Dry Lake and the old mining townsite of Delamar. The ''Delamar Mountains Wilderness Area'' covers the southern portion of the range.〔(Fact sheet: Delamar Mountains Wilderness, Nevada Bureau of Land Management )〕 ==Geology== The range contains Paleozoic sedimentary rocks which were faulted and deformed during the Sevier orogeny. Two periods of silicic volcanism occurred during the Cenozoic producing multiple layers of ash flow tuff. The first occurred during the Oligocene to early Miocene (27 to 18.6 Ma) with sources from the Central Nevada Caldera Complex and Caliente Caldera events. The Kane Springs Wash Caldera in the central part of the Delamar range and extending into the adjacent Meadow Valley Mountains erupted at 14.5 Ma producing the Kane Wash Tuff.〔Page, W.R., 1995, ''Low Angle Faults in Devonian Rocks of the Southern Delamar Mountains, Lincoln County, Nevada,'' pp 205-216 in USGS Bulletin 2056-G〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Delamar Mountains」の詳細全文を読む スポンサード リンク
