| 摘 要： | 研究区内太古宙变质岩、长城系、蓟县系白云岩及燕山期花岗岩体内有较多辉绿岩墙（脉）侵入，其强烈的蚀变和矿化与本区银、金多金属矿床关系密切，严格制约着银、银金、银铜矿体的展布。有的蚀变辉绿岩、辉绿蚀变岩与矿石共生或本身即为浸染状矿石。此外燕山晚期形成的辉绿岩墙（脉）对铅锌矿床起到了再次富集成矿作用。辉绿岩墙（脉）是本区银、金多金属矿床明显的直接的有效的找矿标志。

| Abstract: | There are massive diabase dyke （vein） in Archean metamorphic rocks, Changcheng system, dolomite of Jixian system, and granite body of Yanshanian period, and its strong alteration and mineralization had close relation with Ag - Au - polumetallic deposit, and control the distribution of Ag, Ag - Au, Ag - Cu. Some of altered diabase, diabasic altered rocks accrete with ore or as disseminated ore itself. The diabase dyke （vein） of Later Yanshanian spurred the re - concentration of Pb - Zn ore - formation. The diabase dyke （vein） is the obvious, direct and effective prospecting criteria for Ag - Au - polymetallic deposit. |
