The massive sulphide, lead-zinc, iron, copper deposits of the former and the porphyry copper-molybdenum deposits of the latter are the main ore types in the region.3. The conclusions drawn through the research on the Re-Os isotopic geochronology of the Chilu Mo deposit are as follows:(1) the model age of the Chilu Mo ore deposit is 105.6Ma, closely to the 87Sr/86S isochrone age of the porphyric granite, adamellite. So they are closely correlated in the genesis, and both are the production of magmatic evolution of the late Yanshan.

Cu、Mo、Pb、Zn、Au为区内优势矿种。3、对赤路钼矿床的Re—Os同位素年代学研究得出如下结论：(1)赤路钼矿的矿化模式年龄为105.6Ma，与似斑状花岗岩、二长花岗岩等的87Sr/86Sr等时线年龄115±4Ma较接近，表明二者在成因上密切相关，同属燕山晚期岩浆演化的产物；(2)赤路钼矿床具有辉钼矿中Re、Os含量偏低，低87Sr/86Sr初始值和硫同位素组成接近陨石硫等特点，表明其为成矿物质来源于地壳深部，且为斑岩型钼矿床。

All these indicate that the gold and cobalt ores were formed later than the iron ores. Chemical analyses of the ores and wall rocks suggest that the south and north iron ore zones were formed by the same ore_forming process. The differences of Au, Cu and Ni contents between these two iron ore zones might have resulted from the late intrusion of monzonite.

元素地球化学分析结果表明，矿区内南、北矿带总体上是同一期成矿作用的产物，它们的少数成矿元素含量和矿石磁性之间的差别，可能与南矿带曾遭受后期二长岩侵入活动的影响，造成了部分成矿元素的活化迁移有关。
