摘要
根据河南省区域性断裂构造和地层区划,结合以往全省石墨矿产勘查成果及收集相关资料及野外调查,初步确定了河南省石墨矿产资源的分布特征,划分出华北地台南缘灵宝—鲁山—舞阳、秦岭—大别山褶皱系北秦岭朱阳关—柳泉铺、东秦岭复杂构造带南支荆紫关—师岗复向斜北翼3个主要石墨矿带。依据分布特征,太华群水底沟组地层为Ⅰ号分布区内石墨矿的直接找矿层位,秦岭群雁岭沟组、陡岭群大沟组地层分别为Ⅱ号、Ⅲ号分布区内石墨矿的直接找矿层位。
In accordance with the regional geological fracture structure and stratum distribution in Henan province,combined with the previous provincial graphite mineral exploration outcomes and collecting relevant data,this article preliminarily described the distribution characteristics of graphite mine in Henan province,three main graphite concentration distribution bands were divided,which are from Lingbao-Lushan to Wuyang which belongs to north China platform,and from Qinling-Zhuyangguan which is a part of north Qinling mountain and belongs to Dabieshan fold system to Liuquanpu,as well as from Jingziguan which is located in the south branch of Qingling complicated conformation band to Shigang synclinore north wing respectively.Based on the distribution characteristics,the Shuidigou stratum of Taihua group is No.1 graphite distribution area,and the Yanlinggou stratums of Qinling group and Dagou stratums of Douling group are No.2 and No.3 graphite distribution areas.
