| 中文摘要: |
| 萨尔布拉克金矿断裂带主断面连通性不强,多为尖灭侧现,以脆性破碎为主,兼具韧性走滑性质;高渗透性和高扩容性的断层破碎带是导矿、配矿、容矿的控矿构造;矿体沿主断裂带在走向、倾向和垂向上均具有似等距性分布规律。矿区内的矿体产状直接受断裂的控制,总体上与主断面的产状一致,断裂内的特定部位有利于矿质富集;与矿化关系密切的毒砂-黄铁矿化、硅化、碳酸盐化是直接的找矿标志,所形成的蚀变岩多为近矿围岩或本身就是矿体。 |
| 英文摘要: |
| The main fault plane of the fractural zone in Sarbulak gold deposit is not so continuously that it pinches out and reappears laterally and is characterized mainly by brittle then ductile and strike-slip deformation.It is a highly permeable and dilatant structure thus a ore-fluid leading and accumulation and ore-host fracture zone.Ore bodies are equally spaced in strike,dip and vertically and their occurrence is generally coincided with that of the fractural zone and is directly controlled by the fracture.Ore materials are concentrated in the proper position.Arsenopyrite,pyrite,silicification and carbonation are closely related to ore thus the ore-searching marks.The arsenopyrite-pyrite rock,silicified and carbonized rock are generally the ore-host rock or they are themself ores. |
