| Zhao-Ping fault zone is a branch of the system of the Tan-Lu fault zone and one of themost important metallogenic belts of gold in the Jiaodong area as well. About50%ofdeposits are stored in the Zhao-Ping fault zone. The research of this area studied bypredecessors placed extra emphasis on observation and analysis of the deposit scale. Theywere lack of the research and summarization of the whole metallogenic belts systematically.Therefore, this paper studies the regulation of mineralization and domination of minerals bymeans of analyzing the structure of the Zhao-Ping fault zone.On the basis of abundant field research and areal geology, this paper collectspredecessors’ achievements and data fully and uses the theory ofconstruct diagenetic mineralization as the guide to investigate and research systematicallysome typical gold mine such as Ling-long-xi-shan, Da-yin-ge-zhuang, Xia-dian, by meansof analyzing history of geometrical features, kinematic characteristics, tectonic evolutionand mineralization. At the same time, it makes sure that characters of motion of theZhao-Ping fault zone in different periods, regularizing tectonic classification and form offault-dominating minerals, constructing tectonic symbol of mineralizing forecast of faultzone and distinguishing symbol of hidden minerals. Output of the ore body is controlled bymulti-level fractures. The main tectonic pattern includes the broom shape,“λ” shape,“Z”shape and so forth. Fault-dominating minerals are displayed on attitude of ore bodycontrolled by fractures, distribution, part-enrichment of mineralization, types ofmineralization and Wall-rock alteration strength.The tectonic symbols of mineralization forecasting include the crest of fault along withorientation, place of tendency from slow to sweeping, fractured altered rock zone, mylonitezone, cataclasite zone, secondary fractures and joint zone, overlay between ductile shearzone and brittle fracture and fracture transition cross parts and so forth. |
