摘要
内蒙古中西部具有优越的晶质石墨矿成矿环境,本文通过分析集宁地块至阿拉善地块区域地质背景、晶质石墨研究现状及矿床分布,剖析典型矿床地质特征,宏观总结矿床演化规律,微观研究其固定碳含量、同位素特征、显微形貌特征和激光拉曼光谱等特征,总结了研究区成矿规律,阐明了晶质石墨矿床分布不完全受孔兹岩系控制、变质程度与资源储量规模没有必然联系、成矿物质来源为有机质成因等观点;提出了区域变质-接触变质型矿床概念,建议单独划分其类型;指出新的有利于晶质石墨找矿的远景区和靶区。
The Middle and Western Inner Mongolia has a superior crystalline graphite mineralization environment.This paper analyzing the regional geological background,crystalline graphite research status and deposit distribution of the Jining block to Alashan block,the geological characteristics of typical ore deposits are analyzed.In this paper,the evolution law of deposit is summarized and the characteristics of fixed carbon content,isotopic characteristics,microscopic morphology and laser Raman spectrum are studied.The metallogenic regularities of the study area are summarized,and pointing out that the distribution of crystalline graphite deposits is not completely controlled by the Kongzi rock series,the metamorphic degree is not necessarily related to the scale of resource reserves,and the source of ore-forming materials is organic matter.The concept of regional metamorphic-contact metamorphic deposit is put forward.It is recommended to separate the types and pointing out that the new prospective area and target area are favorable for crystalline graphite prospecting.
