| 摘 要： | 若尔盖巴西金矿床产于中上三叠统碎屑岩与印支－燕山期闪长岩入体的接触过渡带中，金矿化围冉为交代硅化石英岩，在矿石中发现铜矿矿。该矿物为缺氧、硫并在较高熔融温度的强还原环境中的产物，根据本区含矿岩石中发现火山凝灰质碎屑岩及邻区三叠纪时期存在区域裂陷与岩浆活动的特点，认为巴西金矿的成矿来源与海底火山喷发作用有关。

| Abstract: | The Baxi gold deposit in Roergai occurred in the contact transition belt between the upper clastic rocks of the Triassic Series and diorite intrusive of the Indo Yenshanian stage. The country rocks of gold mineralization have replaced silicified quartzites in which the copper zinc ores are discovered. The ores are poor in oxygen or sulfur and are the products of strong reduction at higher melting temperature. According to the volcanic clastic rocks discovered in the ore bearing rocks in this area and the regional fault depressions and the features of magmatic activities in the Triassic period in the adjacent area, the author holds that the origin of ore forming materials is related to sea floor volcanic eruption. |
