通过对乌兰乌珠尔-祁漫塔格地区华力西-印支期岩浆作用与成矿关系的分析和对比.进一步说明祁漫塔格东段早、中泥盆世侵入岩成矿作用不明显;早二叠世侵入岩形成的矿产不多,成矿作用一般;晚三叠世侵入岩在一定的围岩条件下常形成矽卡岩化,成矿作用较为明显.为该区主要成矿期;早侏罗世侵入岩的外接触带常形成矽卡岩化,成矿作用较好,也是测区内主要的成矿期之一。矿床类型以矽卡岩型为主。
通過對烏蘭烏珠爾-祁漫塔格地區華力西-印支期巖漿作用與成礦關繫的分析和對比.進一步說明祁漫塔格東段早、中泥盆世侵入巖成礦作用不明顯;早二疊世侵入巖形成的礦產不多,成礦作用一般;晚三疊世侵入巖在一定的圍巖條件下常形成矽卡巖化,成礦作用較為明顯.為該區主要成礦期;早侏囉世侵入巖的外接觸帶常形成矽卡巖化,成礦作用較好,也是測區內主要的成礦期之一。礦床類型以矽卡巖型為主。

Analyzing the relationship between the magmatism and metallogenesis of Varisean-Indosinian stage in Wulanwuzhuer -Qimantage area shows that the metallogenesis of the intrusive rocks of early-medium Devonian epoch in eastern segment of Qimantage is not distinct;the metallogenesis of the intrusive rocks of early Permian epoch is normal;the intrusive rocks of late Trissie epoch is usually companied with skarnization under a certain wall rock condion. The metallogenesis is obvious and it is the main metallogenie epoch ; the cxsocontact zone of the intrusive rocks of early Jurassic epoch is usually companied with skarnization. The metallogenesis is better and it is also the main metallogenic epoch. The skarn type is the main deposit type.
