| 摘 要： | 国内外贵金属与控矿构造研究表明,韧性剪切带,特别是发育在太古宙古老陆核花岗-绿岩地体中的韧性剪切带是最重要的控矿构造.文章列举夹皮沟韧性剪切带、小四平-南岔韧性剪切带、山门-叶赫韧性剪切带等实例对吉林省东部韧性剪切带的展布规律、基本特征及其控矿作用进行了详细论述,总结了韧性剪切带与金、银矿产的关系.

| Abstract: | Base on the study about precious metal mineralization and ore-controlling structures, it is realized that ductile shear zones, especially those developed in the Archean granite-greenstone belt, are the most important ore-controlling structures. The spatial distribution, basic features and ore-controlling significance of those shear zones in the eastern Jilin province have been discussed. Moreover, the relationships between precious metal mineralization and ductile deformation have been discussed. |
