摘要
根据招掖地区金矿床的空间展布及其结构特征研究,本文提出并讨论了本区金矿化的三种分带型式及其形成机理.即:(1)受控矿断裂性质制约的矿化类型分类;(2)由多阶段矿化形成的脉动分带和,(3)由同一阶段矿化形成的沉淀分带.
Based on the investigation of spatial distribution and texture features of the gold depostits in Zhaoyuan - Yexian region、Three types of zonality and the mechanism of their formation are proposed and discussed in this paper. i. e. (1) Zoning of mineralization types caused by the mechanical properties of ore-controlling fracture, (2) Pulsation zoning caused by the mineralization of multiple stages and, (3) Zoning caused by precipitation in the same mineralization stage.
