Ore deposit, have been studied detailly; the orebody pattern (sedimental bedded ores combined with stringer ores of hydrothermal origin) is also outlined; four metallogenic epoches are devided; the zoning of mineralization (including zones of ores, elements, mineral assemblages and temperature of mineralization) have been depicted; the main types of wall-rock alteration are characterized as propylitization of basic rocks and pyritization-sericitization-silicification of acidic pyroclastic rocks; the origin of ores and seven kinds of main minerals have been studied; and the metamorphism and deformation of orebodies is thought mainly due to the shearing and the intrusion of subvolcanic rocks

研究了七个矿化带特别是I号矿床的矿床地质特征，描绘了矿体的双层结构(沉积矿石与热液充填交代的细网脉状矿石)，划分了四个成矿期次，区分了矿化分带(包括矿石组构的成因分带、元素分带、矿物组合分带、温度分带)，指出了围岩蚀变的主要特征是细碧岩青盘岩化而石英角斑质凝灰岩黄铁绢英岩化；对矿石及七种主要矿石矿物的成因作了研究；探讨了矿体的变质、变形，指出韧性剪切及次火山岩侵入的热力作用和应力作用是导致矿体变质变形的主要原因

Yanbian region lies in the eastern segment of north margin of North China slab, situating on the intersect point of North China, Sibiric and the pacific slab.
