| 摘 要： | 多宝山—黑河地区位于大兴安岭成矿省北东段，区内已探明的金、铜等20多个矿种的资源储量居黑龙江首位，其中斑岩型铜矿为区内重点勘查资源，其赋存于侵入铜山组砂砾岩和多宝山组安山岩的花岗斑岩和花岗闪长岩中，蚀变明显，主要受地层和北东、北西向断裂控制。充分收集并总结前人的研究成果，对研究区的区域地质背景、矿床地质特征、成矿类型、控矿要素、物化遥异常等信息进行综合，建立多宝山式铜矿找矿预测模型。基于该预测模型，采用证据权法分析并圈定8个斑岩型铜矿成矿远景区，可作为研究区进一步勘探找矿工作的重点。

| Abstract: | The Duobaoshan-Heihe area is located in the northeast section of the Greater Khingan metallogenic Province. The proven reserves of more than 20 kinds of mineral resources such as gold and copper in the area rank first in Heilongjiang Province. Porphyry copper deposit is one of the key exploration resources in the area, which occurs in granite-porphyry and granodiorite intrusions into the conglomerate of the Tongshan Formation and andesite of Duobaoshan Formation. It is obviously altered and mainly controlled by strata and NE-trending and NW-trending faults. By fully collecting and summarizing the previous research results, the regional geological background, geological characteristics of ore deposits, metallogenic types, ore-controlling elements, geophysical, geochemical and remote sensing anomalies and other information in the study area were integrated, and the prospecting prediction model of the Duobaoshan copper deposit was established. Based on the prediction model, the weight of evidence method was used to analyze and delineate 8 porphyry copper ore-forming prospect areas, which can be the focus of further mineral resources exploration in the study area. |
