摘要
论述了邓家山铅锌矿床含矿硅质岩.即含矿层或矿源层的特证.矿区构造变形特证,滑断构造的存在,劈理的广泛发育,片内无根褶皱的出现.剪切褶皱和紧闭倒转背斜等和4期构造变形序列.从动力作用成矿观点和动力矿床形成的基本条件,来认识邓家山铅锌矿床地质特征和分析矿床形成机制,提出了邓家山铅锌矿床为层控型动力热液成因矿床的新认识.
The characteristics of the ore-bearing siliceous rocks- the ore-bearing beds or source-beds of Dengjiashan Pb-Zn deposit, and the ore-field structural deformation characters- the existence of slide faults, the intensive development of axial plane cleavage, the occurrence of rootless intrafolia folds and the discovery of shear folds, isoclinal overturned anticlines and four periods of superimposed deformation are demonstrated in this paper. From the viewpoint and the basic conditions of dynamo-metallogenesis, the geological characters of the deposit are discussed and its forming mechanism is analyzed, and a new suggestion for the mechanism of Dengjiashan Pb-Zn deposit-the stratabound dynamic- hydrothermal Pb-Zn deposit is presented here.
