礼岷金矿带东部脉岩与浸染型金矿的关系

Relationship between vein rock and disseminated gold deposits in the east of Liming's auriferous belt

在礼岷金矿带上与浸染型金矿有关的脉岩 ,空间上与矿化密切伴生 ,时间上晚于矿化 ,成因上脉岩和矿化均与中川岩体有关 ,为同一岩浆—构造事件不同阶段演化伴生的产物。从岩石学、岩石化学、微量元素、同位素等方面讨论了脉岩的地质特征及其与金矿化的关系 。

The vein rock related with auriferous ore in Liming's auriferous belt became the production of the different evolution stages of the same magma structure event, closely associated with mineralization in space ,little late for mineralization in time and related with rock body of Zhongchuan .Author discussed geological characters of vein rock and co-relation with auriferous mineralization, and indirectly concluded the relationship of auriferous ore and rock body.
