一、地层区调查区位于西准噶尔北部。主要属于和布克赛尔蒙古自治县的沙尔布尔提山,乌吐布拉克南洪古勒楞南部低山,哈拉阿得里克山东端以及该县与吉木乃县交界的萨吾尔山南北坡。大致北纬46°40′-47°20′东经86°-87°。古生代地层出露有中上奥陶统、志留系、泥盆系和中下石炭统,其中以志留系、泥盆系、石炭系分布最广泛,奥陶系仅在南部呈断块零星分布。由于沉积建造、岩相、生物群性质、地质发展情况的不同。今年工作地区可以分为两个Ⅲ级地层区:
First, the stratum area survey area is located in the northern part of West Junggar. Mainly belong to the Sorker Hill and Buksere Mongolian Autonomous County of Sarbulty Hill, Utumbulake South Hurghaler southern low mountain, the eastern end of the Hala Adrick Hill and the county and the junction of Jimo County, North slope. Latitude 46o 40’-47o 20 ’north latitude 86o-87o longitude. The Paleozoic strata are exposed in Middle-Upper Ordovician, Silurian, Devonian and Middle-Lower Carboniferous, among which Silurian, Devonian and Carboniferous are the most widely distributed. Ordovician is only scattered in the southern part distributed. Due to sedimentary construction, lithofacies, biota, and different geological development. This year’s work area can be divided into two Grade III stratigraphic zones:
