Study Of General Information Metallogenic Prediction In Gold Deposits Of Zhaoping Fault Zone

Zhaoping fault zone is the most important belt of gold mineralization in north-western Jiaodong. Based on the systematic collection of past geological, geophysical, geochemical and other comprehensive information and research in this area related to gold based on the results, focusing on the gold deposit (body) of the controlling geological conditions of deposit (body) of the spatial location and occurrence law, and geophysical and geochemical and gold deposits (body) of the internal correspondence, to establish a prospecting model, and on this basis, the central location of the fault zone were Zhaoping metallogenic prediction. Cognition and the results obtained are as follows:(1) NE and NNE trending faults are the main lead ore mining and construction, in turn broken by the steep slows Department and the tendency of the main office for the occurrence of parts of gold, while the fracture of composite parts and the side branch, faulted cross-site position is favorable and enrichment of gold.(2) with exquisite granite and gneissic granodiorite intrusion Guojialing the site is the gold mineralization in the most favorable site, and lamprophyre dikes of the gold mineralization appears favorable.(3) potassic and phyllic wall rock alteration is the main type of mineralization can be used as a direct prospecting criteria.(4) Geophysical studies show that negative anomalies of low magnetic and low resistivity high polarization is the main symbol of geophysical prospecting. According to CSAMT information, resistance to high resistance rate of the transition zone of low resistance, slowing down the steep gradient from the location of favorable ore-forming parts.(5) geochemical primary halo results show that the deposit of the original halo obvious zoning characteristics, and Au、Ag、Cu、Pb、Zn、As、Sb、Bi、Hg and other indicator elements are abnormal and corresponding alteration zone and ore bodies. the axial zonation.(6) According to the mineralization law and geophysical, geochemical features, the establishment of a geological, geophysical and geochemical prospecting model, to predict and the division of target mineralization.
