Characteristics and Prospecting Direction of Limestone Ore Resources in Elbin Paleozoic Residual Basin
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 D2s3 Formation of Middle Devonian Saalming Formation,D2a Formation of Middle Devonian Alatage Formation and C1yy 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.
