西南天山巴什苏洪方解石矿床的初步发现
|
摘要
通过详细的野外地质工作,结合室内分析,在新疆阿图什市哈拉峻乡巴什苏洪村初步查明了一个超大型方解石矿床。在西南天山地区针对这种类型矿床的找矿成果,尚属首次。在槽探和矿石的地球化学数据中,通过CaO的含量得出CaCO_3的含量在98%～99%之间,已经达到或超过Ⅰ类食品级重质碳酸钙的标准,并且有害元素Hg、Cd、Pb、Ba等的含量均达到食品级重质碳酸钙的标准,甚至远低于标准值。以目前的工作程度初步估算出矿石量可达1亿t,已经达到超大型方解石矿床的规模,潜在经济价值巨大。同时,通过对西南天山地区区域地质背景、地层、构造和岩浆岩格架探讨,认为在本区寻找这种类型矿床具有广阔的找矿前景。
Through te detailed field geological work,combined with analysis in the laboratory,a super calcite deposit is initially identified in Bashisuhong Village,Halajun Town,Atushi City,and Xinjiang Province. It is the first time to explore this type of deposit in the southwestern of Tianshan area. In geochemical data of ore and samples in the groove,the content of CaCO_3 is between 98% and 99% by the content of CaO,which has reached the standard of class I food grade heavy calcium carbonate,even exceeded it. And the content of the harmful elements all reach the standard of food grade heavy calcium carbonate,even far below the standard value,such as Hg,Cd,Pb,Ba and so on. Based on the current work,the amount of ore can reach 100 million tons,which has reached the scale of the super large calcite deposit,and shows huge potential economic value. At the same time,through the discussion of the regional geological background,stratigraphic,tectonic and magmatic rock frameworks in the Southwestern of Tianshan area,it is believed that the search for this type of deposit in this area has broad exploring prospects.
