许许沟位于塔里木地台西南缘的铁克里克台褶带内。地势高峻挺拔,山峰林立,属昆仑山前缘的组成部分。此区中元古界一九五七年曾被十三大队划为下古生界,并建立了博查特塔格岩系(e—O)b~(?)。七七年我队综合组在本区找磷过程中,发现了含叠层石的层位,并经他们研究对比后将该岩系暂定为震旦系,建立了卡拉克尔组、布喀吐维组、博查特塔格组。1978年我们在该区进行了1:5万以磷为主的普查找矿,较详细地测制了地层剖面,较系统地采集了微古样、叠层石样,试图对此地层进行较详细的对比和划分。由于应时该剖面叠层石样经新疆地质局科研所高振家鉴定,其中大部分样品不能鉴定,仅有少量成果,因此
Xu ditch located in the southwestern margin of Tarim platform within the iron Creek fold belt. The terrain is tall and straight, the peaks everywhere, is part of the Kunlun Mountains front. In 1957, the Proterozoic in this area was designated as the Lower Paleozoic by the 13th Brigade and the euphemism e-O b ~ (?) Was established. During the discovery of phosphorus by our team in 1977 in this area, we found the strata with stratigraphic layers and tentatively identified them as Sinian by their study and comparison. The kalakir group, cloth Kashuwei group, Bo Chattertag group. In 1978, we conducted 1: 50000 phosphorus-based census prospecting in the area. We measured the stratigraphic sections in more detail and systematically collected micro-paleosamples and laminated stone samples in an attempt to compare this stratigraphy Detailed comparison and division. Due to the stratigraphic stratigraphic cross-section should be identified by the Institute of Geological Survey of Xinjiang Ge Zhen, most of which samples can not be identified, only a small amount of results, therefore
