与石炭系有关的沉积矿产主要有石膏和煤,其次为铁、耐火粘土、水泥灰岩、熔剂白云岩等。现分述如下。 一、石膏 石膏分布在祁连山区,集中于西段疏勒南山及东段天祝、景泰一带。 在疏勒南山,石膏赋存于城墙沟组上部。区域分布范围很大,西自盐池湾以北伊和阿尔嘎勒台,东达考克赛一带,断续延展百余公里。以伊和阿尔嘎勒台矿点为例,矿体呈层状、似层状,含矿层位稳定。
Sedimentary minerals related to the Carboniferous are mainly gypsum and coal, followed by iron, refractory clay, cement limestone, flux dolomite and so on. Now is as follows. First, gypsum plaster distributed in the Qilian Mountains, concentrated in the western section of Shule Nanshan and eastern Tianzhu, Jingtai area. In Shule Nanshan, gypsum occurs in the upper part of the city wall ditch group. The region has a wide range of distribution. From west of Yanchi Bay to Iraq and Argaleta station, East Codai area, intermittent extension of 100 kilometers. Take the Iraqi Algaleta mine site as an example, the ore body is stratified and stratified, and the ore-bearing strata are stable.
