| 摘 要： | 在上杭—云霄地区存在桃溪、大禾坑—丰稔、东山三条北北东向韧性剪切带,以发育各种类型的糜棱岩为主要特征。它们分别形成于晋宁期—加里东期、加里东期—印支期栩燕山期,本文着重讨论金元素在这三条韧性剪切带中富集规律,为在这一地区进一步寻找韧性剪切型金矿床提供基础性资料。

| Abstract: | There are three NNE-trending ductile shear belts (Taoxi, Dahekeng-Fengren and Dongshan ductile shear belts) in the Shanghang-Yunxiao area of northwestern Fujian, Which are characterized by the development of different kinds of mylonite. The Taoxi ductile shear belt was formed in the Jinning-Caledonian period, the Dahekeng-Fengren ductile shear belt in the Caledonian-Indosinian period and the Dongshan ductile shear belt in the Yanshanian period. The authors herein make a discussion of gold enrichment in the three ductile shear belts, which can provide the basic information for further exploration of the ductile-shear-type gold ores in the area. |
