| 中文摘要: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。 |

| Abstract:Based on an analysis of structures, this paper emphatically studies characteristics of mineralized fissures as well as channels, modes and genetic mechanisms of liquid migration.The authors consider that differential mineralizations mainly result from different fissures, and there is no clear boundary between these microstructures. The mineralized fissures exist in two forms:extension of micro-fissures driven by liquid and extension of vein fissures caused by shear and tension. Liquid migrates mainly by way of vacuum pump. Different genetic mechanisms and migration forms lead to different mineralization characteristics. |
