摘要
本文从矿床特征入手,在对控矿构造进行具体分析的同时,论证了构造与成矿的时空关系,认为控矿断裂是由内接触带隆起部位的节理发展而成的;矿液致裂使含矿断裂规模进一步加大,矿液自接触带向下倒灌,因而矿化具逆向分带现象,矿体呈大脉状产出,矿床不具“五层楼”特征。
Through systematic studies on the ch aracteristics of the ore deposits an d ore-controlling structures,the time-space relationship betwee n structures and ore formation,the a uthors think that the Q-joints of the uplifted areas in the endocontacts w ere further evolved into ore-contro lling structures,and ore-fluid flo wed down from the contact strips,conseq uently the mode of ore bodies occurre nce was large-vein type and the mineralization revealed the phenom enon of reverse zoning but do not takk on the characteristics of'Five-storey'.
