| 摘 要： | 位于桂东北姑婆山复式岩体西南接触带的水岩坝锡钨矿田，其主要矿床在控矿因素上具有以构造控矿为主导因素的特点，本文通过对矿田内主干断裂的岩组运动学、动力学及变形岩石有限应变分析。对本区自地洼区阶段以来，燕山期花岗岩体的侵入所造成的矿田构造格局进行了系统的研究；然后．根据烂头山黑钨石英脉型矿床的特征，按脆－韧性剪切的原理，从递进变形的角度指出本区脉型矿床的成矿规律．模式和找矿方向，并提出该矿床为构控型多因复成矿床。

ON EVOLUTION OF METALLOTECTONICS AND THE MECHANISM OF STRUCTURES CONTROLLING VEIN DEPOSIT AT THE SHUIYANBA ORE FIELD,GUANGXI |

| Abstract: | he Shuiyanba W Sn ore field is situated on the southwest outer contact zone of the Guposhan polygranite instrusive of northeast Guangxi,China.This major ore deposit is greatly controlled by struetures. Through analysis of petrofabrie dynamies and kinematies and finite strain analysis of the major faults, the tectonic framework which has formed since Yanshanian polygranite emplacement in the diwa stage in this region was investigated. Applying the brittle-ductile shear principle to the Lantoushan quartz vein w deposit,a metallogenic model and ore prospecting direetion for the vein deposit were conceived which incorporated the major controlling structural factors. |
