黑龙江东宁洋灰洞子地区铜多金属矿床成矿规律与成矿预测

Mineralization regularities of Yanghuidongzi copper-polymetallic deposit in Dongning County,Heilongjiang Province,and mineralization prediction

黑龙江洋灰洞子铜多金属矿床地处兴蒙造山带东段、吉黑褶皱带北部太平岭隆起带与老黑山断陷复合部位。为了揭示其成矿规律和成矿潜力,开展了区域成矿规律与成矿预测的研究工作。在分析洋灰洞子铜多金属矿床成矿地质背景和矿床地质特征的基础上,发现区内元素的区域分布规律为:区内北部以寻找Sn、Mo矿为主,南部则寻找Cu、Pb、Zn矿为主。在此基础上,初步确定了3个重点普查找矿靶区:二段林场Cu、Pb、Zn多金属普查靶区,杨木林Pb、Zn矿普查靶区和路明山Sn、Mo多金属普查靶区。

Yanghuidongzi copper-polymetallic deposit in the province is located in anoverlapped area where three regions, the eastern part of the Xingmeng orogenic belt, Taipingling uplift in the north of Jihei fold belt and the Laoheishan depression meet. In order to reveal its metallogenic regularity and mineralization potentiality, research on regional mineralization regularity and mineralization prediction is on the move. The regional distribution pattern of elements through the analysis of the metallogenic geological background and geological characteristics of Yanghuidongzi copperpolymetallic deposit is studied and the results show that the northern area is mainly for Sn, Mo ore and the southern area for Cu, Pb,Zn ore. Based on this evidence it will make three prospecting targets：Cu, Pb,Zn polymetallicgeneral survey target at Erduan forest area, Pb, Zn general survey target at Yangmulin area and Lumingshan Sn, Mo polymetallicgeneral survey target.
