蒙古国巴彦乌列盖诺根诺儿铜矿地球化学特征

Mongolia's Bayan olgii Nobel root Lora geochemical characteristics of copper

位于蒙古国巴彦乌列盖省西部的诺根诺儿铜矿矿体主要赋存于中奥陶世一套深海相沉积建造,矿床产出与地层层位、区域构造和科布多深大断裂密切相关。通过对矿石、围岩的矿物组成、结构构造、化学成分、包裹体地球化学研究,矿石及围岩均以富SiO_2、TFe、Cu、Mn、Ba、Ca、Zn、Pb、Mg、As、Sb、S、C、B、K等元素为特征,成矿元素Cu、Zn、Pb等主要元素主要来源于奥陶纪地层及超基性岩浆岩,O、C主要来自海上,铜矿床成因属于海底喷流沉积型。

Nobel root Lora copper deposit occurs in Mongolia province in Western Bayan olgii Middle Ordovician a deep sea facies sedimentary formation, deposits and strata, tectonic and deep faults are closely related to Khovd. Based on the ore and surrounding rock mineral composition, structure, chemical composition, inclusion geochemistry, ore and rock are characterized by rich in SiO2, TFe, Cu, Mn, Ba, Ca, Zn, Pb, Mg, As, Sb, S, C, B, K and other elements, ore-forming elements Cu Pb, Zn, etc. the main element mainly originates from the Ordovician strata and ultrabasic magmatite, O and C mainly comes from the sea, copper deposit belongs to the type of exhalative sedimentary origin.
