It was excavated by the Provincial Cultural Relics and Archaeology Institute of Heilongjiang in 1996. And 26 tombs were excavated. Hosts of artifacts unearthed including 51 piece of pottery vessels, and the number of iron, bronze tools etc. The tomb’s structure is stonehouse. it is buied’ by coffin chamber tomb door, tormb passage. The Plane of coffin chamber is by rectangle, the secondary burial is most common, moreover many of them were disturbed. Preliminarily study the age of the tombsis around the middle of Bohai period.展开更多
为揭示熊耳山东草沟金矿床成矿流体性质和流体演化过程,以与金矿关系密切的石英为研究对象,开展了系统的野外调查以及流体包裹体岩相学和显微测温研究。结果表明,东草沟金矿体分布主要受构造控制,成矿期次可分为3个阶段:早期石英+绢云母...为揭示熊耳山东草沟金矿床成矿流体性质和流体演化过程,以与金矿关系密切的石英为研究对象,开展了系统的野外调查以及流体包裹体岩相学和显微测温研究。结果表明,东草沟金矿体分布主要受构造控制,成矿期次可分为3个阶段:早期石英+绢云母+黄铁矿阶段、中期石英+多金属硫化物阶段、晚期石英+碳酸盐岩。主要存在5种类型的流体包裹体:D型,含子矿物包裹体;C型,含CO 2水溶液包裹体;LV型,气液两相包裹体;L型,单水溶液包裹体;V型,单水蒸气相包裹体。根据升温过程中子矿物与气泡消失的先后情况,D型包裹体可进一步分为Da型(子矿物先消失)和Db型(气泡先消失)。Da型包裹体子矿物融化温度为211~240℃,均一温度为216~391℃,盐度值32.4%~34.1%;Db型气液相均一温度为172~267℃,盐度值为30.6%~35.8%。C型包裹体笼合物融化温度为-1.9~8.7℃,盐度为2.6%~17.3%,均一温度为276~310℃。LV型包裹体在第1阶段、2a阶段、2b阶段、3阶段LV型均质温度分别为138~310℃、148~403℃、130~255℃、113~199℃;盐度为1.2~11.5 w t%,2.1~21.7 wt%,1.6~15.3 w t%,10.6~15.3 w t%,0.2~13.2 w t%。分析认为,矿区存在不同性质的成矿流体,且初始流体为岩浆热液系统,后期流体不断演化,流体不混溶是金沉淀的主要诱因,而流体混合则导致了银铅锌等的沉淀。展开更多
