着重研究构造作用下成矿裂隙特征和流体的运移通道、方式及成因机制 ,结果认为焦家金矿床差异的矿体矿化特征主要由不同裂隙导致形成 ,微构造裂隙之间没有截然分开的界线 ,常呈渐变接触关系。矿化裂隙成生主要有流体驱动显微构造裂隙扩展和构造剪张形成脉状裂隙两种方式。流体运移以真空泵式为主 ,渗流方式为辅 ,不同的裂隙成生机制和流体运移方式导致形成差异的矿化特征。
The study focuses on the characteristics of mineralization fissures and the migration channels, modes and genesis of fluids under the tectonic action. The results show that the mineralization features of the ore bodies in Jiaojia gold deposit are mainly caused by different fissures, and there is no distinct boundary between microfracture fissures. Often gradient contact. There are two main ways of mineralized fracture formation: fluid-driven microstructure fracture expansion and structure shear fracture. Fluid transfer is mainly vacuum pump, supplemented by seepage flow, and different fracture mechanism and fluid migration lead to the formation of different mineralization characteristics.
