含金剪切带型金矿床的成矿作用

对辽宁省阜新市排山楼金矿床及含金剪切带型金矿床的研究成果进行对比，重新理顺了有关含金剪切带、含金剪切带型金矿床的概念和判别标准.提出了含金韧性或韧脆性剪切带是表壳岩、含金基底岩系形成期或同构造旋回变质变形期的特定产物，故可称之为含金同韧性剪切带.含金同韧性剪切带是一种含金流体的储集构造样式，其成矿作用需要进入浅层次的抬升、成矿流体的汇聚与成矿沉淀的过程.成矿作用过程的差异性（抬升速率不同）导致各种矿化类型的金矿的形成.

METALLOGENESIS OF AURIFEROUS SHEAR ZONE TYPE OF GOLD DEPOSITS

Based on an integrated study and comparison of the shear zone type of gold deposits both in China and abroad, the authors sum up the conception and criterions of auriferous shear zone and gold deposits of the type. By examination of Paishanlou gold deposit in Fuxin, Liaoning Province, it is concluded that the auriferous ductile or ductile-brittle shear zone is the specific result during the forming stage of supracrustal rock and basement rock series or the metamorphic-deformation stage of syntectonic cycle. Therefore, it can be referred as to auriferous syn-ductile shear zone. Such shear zone is a structural style that can preserve auriferous fluid. The metallogenesis for shear zone necessarily undergoes the following process: uplifting to shallow level, convergence of ore-forming fluid and deposition of mineral elements. The variety of metallogenetic process results in different metallization types of gold deposits.
