对金厂峪金矿床深部矿化规律的初步认识

PRELIMINARY STUDY ON METALLOGENIC REGULARITIES IN THE DEPTH OF THE JINCHANGYU GOLD DEPOSIT

根据金厂峪金矿深部（０ｍ～－１０００ｍ标高之间）获得的最新钻孔岩芯资料，结合野外地质观察、室内工作，探讨了该矿床深部的矿化规律以及矿体的产状特征，对探矿工程的布设提出了建议。解释了深部矿化富集与分散的原因，进一步确认了对该区中生代褶皱构造控矿的认识。指出今后深部找矿中应注意发现新的矿化类型，研究中生代褶皱构造与太古代韧性剪切带的关系、蚀变与矿化的关系。

According to the latest bore cores from 0m～-1000m elevation,combined with field work,thin section analysis and chemical analysis,its deep mineralizing regularities and attitudes of ore bodies in the Jinchangyu mine are preliminarily studied,and the suggestion on engineering layout is put forward.The comprehensive study on ore-controlling structures sheds light on the causes of deep enrichment and dispersion of ore-forming elements,and deepen acknowledge of the ore-controlling Mesozoic folds.The further attention should be paid to the discovery of new types of gold deposit,research on relationships between Mesozoic fold and Archean ductile shearzone,and between the alteration types and gold mineralization.
