艾尔宾古生代残余盆地石灰岩矿资源特征分析及找矿方向

Characteristics and Prospecting Direction of Limestone Ore Resources in Elbin Paleozoic Residual Basin

艾尔宾古生代残余盆地是塔里木周边地区重要的石灰岩成矿带,文章基于区域构造建造图及哈和仁郭楞石灰岩矿、野云沟石灰岩矿等典型矿床的研究,对所属成矿带的区域地质特征、成矿时代、赋矿层位及矿石质量分析;认为该成矿带内的中泥盆统萨阿尔明组第三亚组(D_(2)s^(3))、中泥盆统阿拉塔格组(D_(2)a)、下石炭统野云沟组(C_(1)yy)为研究区内主要成矿地层,赋矿岩性为石灰岩、大理岩化灰岩、细粒结晶灰岩,矿床类型为海相沉积型。在研究区内划分出4处成矿远景区,远景区内的石灰岩矿资源丰富,开发利用条件良好。

The Elbin Paleozoic residual basin is an important limestone metallogenic belt in the surrounding area of Tarim.Based on the study of regional structural construction map and typical deposits such as Hahe Renguolin limestone mine and Yeyungou limestone mine,the regional geological characteristics,metallogenic age,ore-bearing horizon and ore quality of the ore-forming generation were analyzed.The D_(2)s^(3) Formation of Middle Devonian Saalming Formation,D_(2)a Formation of Middle Devonian Alatage Formation and C_(1)yy Formation of Lower Carboniferous in this metallogenic belt are the main metallogenic strata in the study area.The ore-bearing lithology is limestone,marbleized limestone and fine grained crystalline limestone,and the deposit type is Marine sedimentary type.In the study area,there are four metallogenic potential areas,which are rich in limestone resources and have good development and utilization conditions.
