浅谈毛家店金矿找矿新发现及意义
Discussion on the New Discovery and Significance of Maojiadian Gold Ore Prospecting

毛家店金矿是一处严格受区域断裂构造控制、且与燕山期黑云母花岗岩和八道河群变质杂岩有密切成因联系的含金混合岩化–高中温岩浆热液型金矿。近几年，在矿山深部勘探过程中，发现深部仍具有较好资源前景，同时发现有工业价值的钼矿体。本文通过对毛家店金矿的地质特征、典型矿脉的产出形态的研究，结合近年的勘探成果，总结该矿山的成矿类型，归纳成矿模式，为老旧矿山深部找矿及相似地质条件下共、伴生矿种的发现提供借鉴及思路。
Maojiadian Gold Mine is a gold-bearing mixed lithification-high-temperature and medium tem-perature magmatic hydrothermal gold mine that is strictly controlled by regional fault structures and has a close genesis relationship with biotite granite in the Yanshan period and metamorphic heterogeneous rocks of the Badaohe Group. In recent years, in the process of deep exploration of mines, it was found that the deep part still has good resource prospects, and at the same time, mo-lybdenum ore bodies of industrial value have been discovered. Through the study of the geological characteristics of Maojiadian gold ore and the output pattern of typical ore veins, combined with the exploration results in recent years, this paper summarizes the mineralization types and sum-marizes the metallogenic models so as to provide reference and ideas for the deep prospecting of old mines and the discovery of common and associated ore species under similar geological conditions.
