摘要
本文认为金顶矿床上含矿带属于景星组(K_1j_1),下含矿带属于云龙组(E_1y)。云龙组上段(E_1y_b)的沉积相属于坡积相和冲积扇,并且论证了金顶矿区的硬石膏层应属于三合洞组(T_3s)。
It is considered that the upper ore-bearing zone in Jinding deposit belongs to Jingxin formation (K1j1); the lower one belongs to Yunlong formation (E1y). the upper member of sedimentary facies of Yunlong formation is presented as sli-derock and alluvial fan. It is demonstrated that the anhydrock layer in Jinding holding belongs to Sanhedong formation ( T3s ) .
