近年来,在华北地台北缘外带的加里东褶皱带上,沿西拉木伦河南岸呈现一条延长200km的以钼为主的多金属成矿带,有望成为我国继小秦岭、燕辽之后的重要钼多金属成矿带。对成矿带内三个典型矿床的初步研究表明,成矿主要与燕山期岩浆活动有关。鉴于该成矿带研究基础薄弱,提出了进一步深入研究工作的建议。

Along the southern bank of Xilamulun River, which located in the Caledonian fold belt of the outer rim of the northern margin of the North China Craton, a 200kin long molybdenum polymetallic metallogenic belt has been found in recent years. The new metallogenic belt should be an important molybdenum polymetallic metallogenic belt after Xiao Qinling and Yanshan-Liaoning molybdenum metallogenic belt in China. Preliminary study on three representative ore deposits of the belt shows that ore-forming main relates to magmatic activities in Yanshanian period. Several advices about further research work have proposed since weak basic study on the belt.
