Magma rock are closely related with mineralization rule, Magma rock category in jiguanzui copper - gold deposit is numerous and have a characteristics of many periods and times, the deposit which mineralized is very comp licated. The article expatiates the correlation of both from different side, arguements the order of magma rock intrusiveness, fore investigative foundation in person last, further enrich and develop the cognition of the magma rock and mineralization rule, and have the important leadingmeaning to the geology work in the future.
Th is text according to data and the experience in m any years, researches and analyzes stratum, structure, magm a rock, wall rock eclipse and the source of m ineralize materia l, m igration and aggradation of them ineral liquid in the taohuazhui copper& go ld& ironm ine bed, , and as to discusses method of the m ineralization , the mineral bed cause of formation.
From 1988,Now J i Guan Zui and Tao Hua Zui mine bed develop s 600m deep ly, long about 1000m, 500m of breadth south to north, add up to 11 layer, although once took p lace the water and mire dash forward of kaste in early days, later hydrology relation became faintly of mineral and rock, so take p lace natural water and mire dash forward of kaste impossibility, The paper discusses the new understanding of the mine bed hydrology geology.
Th is text puts forw ard the duplex construct- the duplex syncline controls the m ineral principle, analyzing the mainmechanism of the structure to contro l them inera,l building up Jiguan zui copper-gold mine bed mineral bodies controls and permits the motive of the mineralizing mode and new principle of ore prospecting.
