本区位于华北地台北缘,加里东褶皱带内。椅山一带的上奥陶-下志留统分布面积约40km~2↖,被华力西晚期,印支-燕山期花岗岩所包围,南侧被小面积中生界掩盖(图1)。一九八四—一九八五年间在金矿专题研究中,我们注意到椅山一带石缝组上段普遍出现的金,多金属矿产。其围岩含相应元素的丰度较高,并且普遍出现相应矿产的矿物组合。通过对矿
The area is located in the northern margin of North China platform, Caledonian fold belt. The Upper Ordovician-Lower Silurian distribution area in the vicinity of Chaiyama is about 40 km ~ 2 ↖, surrounded by Granite in Indo-Chinese-Yanshanian period in the late Waxy West and covered by a small area of Mesozoic (Figure 1). During the study of gold from 1984 to 1985, we noticed the common occurrence of gold and polymetallic minerals in the upper section of the Stone Seams in Chayama area. Its surrounding rock contains the corresponding elements of higher abundance, and generally appear mineral assemblage of the corresponding mineral. Pass the mine
