黑龙江多宝山斑岩型铜矿中低温热液蚀变矿物研究

Research on the medium-low temperature hydrothermal altered minerals from Duobaoshan porphyry-type copper deposit,Heilongjiang province

多宝山斑岩型铜矿位于黑龙江省齐齐哈尔市嫩江县境内,大地构造位置属于中亚-兴蒙地槽褶皱带的东端,是我国著名的超大型斑岩铜矿床。高光谱扫描分析技术是近些年来的新兴技术,在识别中低温热液蚀变矿物方面效果显著。根据多宝山斑岩型铜矿的蚀变发育与成矿特征,选择代表性钻孔岩芯和标本进行高光谱扫描、显微镜下鉴定等,获取与成矿关系密切的中低温热液蚀变矿物的成分与空间变化特征等数据,从而进一步揭示矿床成矿地质规律,为今后矿区的边部、外围和深部找矿乃至后续的矿石开采与综合利用等提供依据。

As one famous super-large porphyry-type copper deposit,Duobaoshan copper deposit locates in the Nenjiang town,Heilongjiang province and tectonically belongs to the east end of the central AsiaXingmeng geocynclinal zone.High spectral scanning is a newly scan technology and it is especially effective on medium-lowtemperature hydrothermal altered minerals identification.Based on the alteration development and mineralization characters of Duobaoshan copper deposit,we especially select some typical cores and samples to high spectral scanning test and microscope identification,and then acquired data like medium-low hydrothermal altered mineral composition and space variation,which closely associated with mineralization.These data also can provide information on the ore-forming law,the deep edge and around area mineral exploration,ore mining and comprehensive utilization and so on.
