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。
茶尖嶺礦區 M28異常分佈區銀多金屬礦的形成與燕山期中痠性淺成巖漿巖有空間、成因聯繫，屬于淺成熱液礦床中的矽卡巖型成因。銀多金屬的成礦是熱液活動、構造作用的產物，根據地層中元素的初始含量及礦源巖來闡明該異常分佈區銀多金屬礦源條件。初步分析認為，闆巖類及閃長玢巖為M28異常分佈區的礦源巖，該異常分佈區地層中銀多金屬元素的初始含量較高，該異常分佈區銀多金屬成礦的礦源條件比較好。

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.
