【正文】 transformation of gold from stable state to an important factor of active state. Generally speaking, temperature, degree of the dissolution of gold also will increase. The microgranular disseminated type gold mineralization, needs certain thermodynamic conditions, to drive the source bed of migration of metallogenic l4l into minerals. Large area as the thermodynamic heat source mainly displays in two aspects of magmatism and tectonic action. Magmatic activity: quartz veins in the area are welldeveloped, eastern outcropped indosinian yanshanian granite, they are after the invasion of the thermal effect produced by a long time, inevitably lead to the emergence of a certain line heating anomaly. Large field of microgranular disseminated type gold deposit is a reflection of the lowtemperature mineralized contact some space and dike rock mass, is actually a reflection of this hot field. Structure: large tectonic environment field gold mining area is located in the north BaYanKaLa indosinian orogenic belt, in the north, nima qing was born with suture zone in late Paleozoic early in the morning, since the late indosinian, regional strong pressive state for a long time. Extrusion effect in rock layer is fold deformation, in the process of rock breaking and displacement, kiic energy is converted into heat energy, a large number of structure movement between rock frictional heat can even reach the level of melt rock. Regional high heat flow value is an important characteristic of extrusion of orogenic belts. Magma heat and heat is the bination of structural, making large area bee a geothermal anomaly area, and has high degree of palaeogeothermal ladder tectonic fracture zone in the area of calcification is geothermal anomaly evidence. the fracture system of form a plete set is ore fluid migration and mineralization locate space. Large field and fractured zone of the microgranular disseminated deposits around together. Ore fracture for deep fault that more than a gander side of deep fault that with basic secondary 6 fracture distribution is parallel, mineralization mainly occurred in the pression shear fracture properties into extensional expansion area. Because of metallogenic enrichment coefficient of the required and to gather the oreforming elements in the big scope, it must have a deep cut fracture exists, to make munication and deep and form massive hydrothermal circulation system, this is the mineralization associated with major fault with time and space. Side of secondary pression shear fracture, can cause good shieldin
