摘　　要：通过对黑龙江省鸡东金场沟角砾岩筒构造特征及其矿化类型的分析研究,对比国内外同类型构造的控矿特点,认为金场沟角砾岩在垂向上具有一定的分带特征,其剥蚀程度表现为:Ⅰ、Ⅳ号片岩角砾岩筒剥蚀程度低,保存较完整;Ⅱ、Ⅲ、Ⅴ、Ⅵ号花岗闪长斑岩角砾岩筒剥蚀到中段。根据角砾岩筒的矿化垂直分带特征,结合本区各角砾岩筒剥蚀程度特点,认为金场沟地区的深部具有较大的找矿潜力。By analysis of the characteristics and mineralization features of the breccia pipe structure in Jinchanggou,and in comparison with the ore-controlling characteristics of the same structure type,and according to the vertical zoning of the breccia pipes proposed by Baker,the authors considered that the breccia was of vertical zoning characters and its denudation degree showed weak and well-preserved for No.Ⅰ,Ⅳ breccia pipes;while the denudation degree for No.Ⅱ,Ⅲ,V and VI breccia of granite-diorite porphyry was moderate.So,based on the study of these breccia pipes and their characteristics,the author concluded that the deposit was of mineral exploration potential at the deep levels.
