摘要
诺格朝特陶勒盖(Nogtsot Tolgoi)铜矿床位于南蒙古的前寒武纪微型大陆南戈壁的卡利登褶皱带中。成矿时代为新古元代—寒武纪,矿体赋存于由碳酸盐岩化的含长石碎屑的砂岩、粉砂岩、泥岩和具花岗岩结构的灰岩组成的构造蚀变带中,呈层状或似层状顺层产出,受地层和构造蚀变带控制明显,属含水火山沉积—后期气液改造成因。通过对中心区矿段进行地质详查,探获该铜矿床品位中等,规模达到中型。除详查中心区矿段之外,通过物化探成果解译及少量钻探验证,发现多处成矿远景区,找矿潜力巨大,并指出下一步勘查的重点为详查区的深部和其他几处远景区。
The Nogtsot Tolgoi copper deposit is located within the southern gobi Pre-cambrian Caledon fold belt in southern Mongolia. The mineralization age of the deposit lasted from Neoproterozoic period to Cambrian period. The copper orebody occurs in the tectonic alteration zone comprising of sandstone with carbonatization, siltstone and mudstone with detrital feldspar and limestone with granite texture in layered and stratoid forms. The ore body is significantly controlled by the strata and tectonic akeration zone. The genesis of the deposit is volcanic sedimentary type superposited by the late stage hydrothermal transformation. The detailed exploration result for the center ore block shows that is the deposit tonnage reaches the medium-sized deposit with moderate copper grade. In addition, the geophysical interpretation and geochemical survey results and test drilling were also carried out. As a result, several ore-forming prospective areas were delineated and it indicated there is a huge prospecting potential. The main task in next stage exploration is to ex- plore the deep-seated copper orebody and main prospective areas in other regions.
