文章研究了安徽绩溪逍遥钨、银、铅、锌、铜多金属矿床成岩成矿地质背景和控矿因素。靠背尖岩体和逍遥岩体与成矿关系密切，它们均为逍遥复背斜控制的小型花岗闪长岩体，且地球化学参数基本相似，同位素测年结果表明两者均为晚侏罗世岩浆侵位的产物，可能表明逍遥岩体与靠背尖岩体在深部同为一个大型岩基。岩体为壳幔混源的I型花岗岩，形成于挤压的构造环境，为中国东部燕山期成岩成矿大爆发的一部分，受统一的地球动力学背景控制。该区具备良好的成矿地质条件，成矿远景乐观。

The rock-forming and ore-forming background and the ore-controlling factors of the Xiaoyao W-Ag-Pb-Zn-Cu polymetallic deposit in Jixi County ,Anhui Province are studied .Kaobeijian and Xi-aoyao plutons have close relation with the mineralization .They are all the small granodiorite con-trolled by Xiaoyao anticlinarium ,and they have similar petrochemical parameters .The isotopic dating results indicate that the two rocks were all the emplacement of magma in late Jurassic ,which probably indicates that Xiaoyao and Kaobeijian plutons are the same big batholith in depth of the earth .The two plutons were the I-type granite from the mixture of crust and mantle ,and formed in the back-ground of compression .They were a part of diagenetic and metallogenetic explosion in the eastern part of China in the Yanshanian period ,and controlled by unified geodynamic background .There are good metallogenetic conditions and optimistic mineralization prospect in this area .
