摘要
扬子地块西北缘、西南缘卡林型金矿床的构造控矿特征主要表现为:被动大陆边缘裂谷(裂陷)带是含金建造形成的区域构造背景;逆冲推覆构造是成矿元素和成矿流体活化、迁移、富集成矿的重要热动力;低级别、低序次的断裂和密集裂隙带是成矿流体的通道和矿体的定位空间。
The ore controlling structure of the sediments hosted disseminated gold deposit in north west and south west margins of the Yangtze plate is mainly summarized as:the rift basin developed along the passive continental margin of the Yangtze plate being the regional tectonic setting of gold bearing formation;thrust nappe fault providing thermodynamic power for mobilization and transportation of ore forming elements and fluid;the lower order fractures playing roles of the passway of fluid and the positional space of ores.
