中文摘要: |
天山—兴蒙造山带是国内晶质石墨矿的主要成矿带,已查明柳毛石墨矿、石场石墨矿等多个大型沉积型石墨矿床,五义屯石墨矿矿床是近年在该带上新探获的一座大型晶质石墨矿床。本文阐述了该矿床的区域地质背景、地球物理特征、矿床地质特征,并分析了矿床成因和找矿方向。结果表明,该矿床是大型沉积变质型石墨矿床,矿体具明显层控特征,主要赋存于中-新元古界麻山岩群余庆岩组中;矿体品位厚度稳定,主要呈大鳞片粒级;矿体与围岩地球物理特征差异明显,具明显低阻高极化特征;本矿床具有成为超大型石墨矿床的潜力,其外围对寻找沉积变质型石墨矿床具有良好的资源远景。 |
英文摘要: |
Tianshan-Xingmeng orogenic belt is the main crytalline graphite ore belt in China. Large-sized graphite deposits have been discovered, such as Liumao graphite deposit, Shichang graphite deposit and the recently discovered Wuyitun crytalline deposit. This paper deals with regional geological background, geophysical and geological characteristics and future prospecting direction of Wuyitun deposit. The deposit is a large-sized sedimentary graphite deposit characterized by stratobound deposit. Ore bodies occur mainly in Yuqing formation of Meso-Neo Proterozoic Ma Shan group. Graphite occurs in large flake crystal. Thickness and grade of the ore bodies are stable. and ore bodies geophysically differs from the wall rock and are characterized low resistance and high polarization. Surroundings of the deposit is potential for prospecting sedimentary-metamorphic graphite deposits. |
