| 摘 要： | 矿区褶皱和断裂相互重叠交错,为含矿热气液的运移提供了导矿及储矿构造。微量元素测定,确定上三叠系地层为锑的矿源层,矿体严格受层位控制,三合洞组灰岩破碎带为含矿层位,是找矿主要标志。依据矿床产出特点及物理化学条件,确认该矿床属中低温热液富集层控矿床。

| Abstract: | The fold and fault in the orefield are superimposed and interlaced one another,which provide the migration,transmission and storage structures for the ore-bearing hydrothermal fluid.According to the analysis of trace elements,the ore source bed is Upper Triassic.And the orebody is controlled strictly by the horizon.The fractured zone in Sanhedong Formation limestone is the ore-bearing horizon,which is the main ore-prospecting index.We can determine that this ore deposit belongs to the medium-low T hydrothermal enrichment stratabound ore deposit according to the occurrence characteristics and physical-chemical conditions of it. |
