Geological characteristics of cobalt deposit in east part of east kunlun and its ore potential 东昆仑东段钴矿地质特征及潜力浅析
Geology of tuolugou cobalt deposit in east - kunlun mountai ns , qinghai province , and the first discussion on its genesis 青海东昆仑驼路沟钴金矿床地质特征及成因初探
Results showed cobalt - tungsten deposit as copper barrier at temperature of 500 and below was superior to nickel , cobalt deposit 当温度低于500时,钴钨合金镀层的防铜渗性能优于后二者。
Meanwhile , properties of cobalt - tungsten , nickel , cobalt deposit as copper barrier at temperature between 400 and 800 were compared 同时比较了在400 800下,钴钨合金镀层与镍层、钴层的防铜渗能力。
Based on distribution of deposits and types and characteristics of mineralization , two mineralization zones could be divided . from west to east they are yongpingchangjie - shuixie - nanjianxinmin middle - high temperature copper - cobalt mineralization zone and zijinshan - maanshan - bijiashan middle - low temperature au - as - sb - hg mineralization zone . the types of deposits in the former are high - middle temperature and middle - low salinity hydrothermal copper - cobalt deposits , and high - middle temperature and mid 进一步揭示出本矿化区成矿元素与成矿温度在平面上的分带性,西南部以cu - co - au的中温-中高温成矿为主,东部及东北部以低温-低中温au - sb - as - hg成矿为主,平面上的这种分带,可能也指示垂直方向的分带。
Based on the studies of microthermometry , gas composition , liquid composition , rare earth elements , ore - forming elements and 13c , d , 18o of fluid inclusions from the mineralization district and the representative deposits , such as zacun gold deposit , shuixie copper - cobalt deposit , shiyancun stibium deposit and bijiashan stibium deposit , two metallogenic fluid systems have been distinguished , i . e . , zijinshan metallogenic fluid system and gonglang metallogenic fluid system in weishan - yongping mineralization district 矿化集中区及扎村金矿、水泄铜钴矿、石岩村锑矿、笔架山锑矿等典型矿床流体包裹体的显微测温、气相成分、液相成分、稀土元素、重金属元素及~ ( 13 ) c , d , ~ ( 18 ) o稳定同位素的研究表明,云南巍山-永平地区铜金多金属矿化集中区存在两个成矿流体系统:紫金山背斜成矿流体系统与公郎弧成矿流体系统。
