| Abstract: | 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. |
