Preservation and peripheral prospecting of Duobaoshan porphyry copper deposit in Heilongjiang Province
-
摘要:
早奥陶世多宝山斑岩铜矿床是古生代多宝山岛弧带上保存最完好的矿床之一，覆盖于矿床之上的奥陶系、志留系巨厚的沉积地层是使其免受剥蚀的关键因素之一. 通过区域铜金矿床（点）产出的地质背景分析，发现构成多宝山岛弧带弧－盆体系的奥陶系及志留系地层发育较齐全，在此基础上叠加铜异常浓集中心的部位，是寻找多宝山式斑岩铜矿的有利靶区，而靶区深部隐伏的埃达克质侵入岩体是实现找矿突破的关键.
Abstract:The Early Ordovician Duobaoshan porphyry copper deposit is one of the best preserved deposits in the Paleozoic Duobaoshan island arc belt, as the overlying thick Ordovician and Silurian sedimentary strata have kept the deposit from being denuded. Through the geological background analysis of the regional Cu-Au deposits/occurrences, it is found that the Ordovician and Silurian strata forming the arc-basin system of Duobaoshan island arc belt are well developed, and the superposed Cu anomaly concentration center is a favorable target area for Duobaoshan-type porphyry copper deposits. The deep concealed adakitic intrusive rock mass in the target area, then, is the key to achieve prospecting breakthrough.
