通过对张里金矿床控矿地质条件调查与分析研究,认为丁家庄段泥云岩对金的富集沉淀起到了一定的作用,是成矿的有利层位;次级萤子洼断裂控制着碱性岩盖-岩床的分布,并与SW向断裂交汇部位控制着含金隐爆角砾岩构造,是金矿成矿的重要构造条件;次火山相碱性角闪二长斑岩、粗面斑岩质隐爆角砾岩是金矿成矿与找矿重要的岩浆岩条件。通过提取综合找矿标志,开展了靶区和隐伏矿体预测工作,圈定A类靶区4处,B类靶区6处,C类靶区2处。
Through the investigation and analysis of the ore-controlling geological conditions in Zhangli gold deposit, it is considered that the mud clinker in Dingjiazhuang section plays a certain role in the enrichment and precipitation of gold, which is the favorable horizon for metallogenesis. The secondary Yingwewa fracture controls the alkali The distribution of the lithostratigraphic-caprock-bedrock and the junction with the SW fault rupture the gold-bearing cryptoexplosive breccia, which is an important tectonic setting for the gold mineralization. The subvolcanic alkaline hornblende breccia, Porphyritic cryptoexplosive breccias are important magmatic rock conditions for gold mineralization and ore prospecting. Through the extraction of comprehensive ore prospecting targets, the prediction of target areas and concealed ore bodies was carried out. Four A-type target zones, six B-type target zones and two C-type target zones were delineated.
