摘　　要：该项研究依托柴家沟钼矿勘查项目,主要目的是研究总结矿床成因及找矿标志,为矿床找矿远景做出评价。在充分搜集了冀北地区钼矿及斑岩型矿床的有关地质资料基础上,综合研究区域地质背景、成矿地质条件和控矿因素,紧密结合矿区地质填图、钻孔控制、化验测试等资料,分析论述了构造活动和岩浆活动与矿化关系,得出柴家沟钼矿属斑岩型钼矿床。依据已知矿体规模、形态特征,通过分析物化探异常,由已知推断未知,对柴家沟钼矿床找矿远景进行了整体评价,为冀北一带寻找同类矿产提供参考。The research is based on the investigation project of the Chaijiagou Mo mine.The main purpose is to study and summarize the genesis and prospecting marks of the ore deposit,and to evaluate the prospecting potential of the deposit.In the full collection of the geological data of molybdenum and porphyry deposits in the north of Hebei Province,comprehensive research on the regional geological background,metallogenic geological conditions and ore controlling factors,combined with geological mapping,drilling,mining area control laboratory test data,the authors have discussed the relationship between tectonic and magmatic activity and mineralization.It is concluded that Chaijiagou molybdenum is a porphyry molybdenum deposit.On the basis of the morphological characteristics of known ore bodies,and the analysis of geophysical and geochemical anomalies,inferred from the known to unknown,ore prospecting perspective is evaluated for Chaijiagou molybdenum deposit.It could also be referred to the exploration for the same type mineral resources in the north of Hebei Province.
