| 摘 要： | 茶尖岭矿区M28异常分布区银多金属矿的形成与燕山期中酸性浅成岩浆岩有空间、成因联系,属于浅成热液矿床中的矽卡岩型成因。银多金属的成矿是热液活动、构造作用的产物,根据地层中元素的初始含量及矿源岩来阐明该异常分布区银多金属矿源条件。初步分析认为,板岩类及闪长玢岩为M28异常分布区的矿源岩,该异常分布区地层中银多金属元素的初始含量较高,该异常分布区银多金属成矿的矿源条件比较好。

| Abstract: | There are space, genetic relationship between the formation of silver polymetallic ore in Chajianling mine M28 abnormal distribution area and Yanshanian intermediate acid hypabyssal magmatite, belongs to the skarn genesis of epithermal deposit. Mineralization of silver polymetallic is a result of tectonic hydrothermal activity and tectonism. According to the initial content and mineral sources of elements in strata, the authors clarify silver polymetallic provenance conditions of the abnormal distribution area. We consider that the mineral sources of M28 abnormal distribution area are slate and dioritic porphyrite, the initial content of the silver polymetallic in strata of abnormal distribution area is higher, which provenance conditions are better. |
