Sb-Li组合:罕见的矿化组合及锂的赋存状态
|
摘要
湖北柘坪锑矿勘查区发现有具一定规模的断裂破碎带型共伴生锂矿,锂主要以锂绿泥石的方式充填在断层破碎带的石英颗粒之间,属于低温热液充填成因。锂与锑的成矿作用均受到断裂破碎带的控制,二者之间在总体上是正相关关系,成矿物质可能均来自于南侧的幕阜山大岩基。这一发现,不但丰富了我国锂矿的类型,而且开拓了找矿思路,为我国新类型锂矿的勘查提供了新的切入点。今后既要注意在锑矿区综合评价锂及其他稀有金属成矿的可能性,也要注意在柘坪锑矿深部及邻区方山锑矿等地对断裂破碎带控制的热液型稀有金属矿化带进行普查勘探,同时还要注意矿化的垂向分带和侧向分带。不排除深部存在隐伏花岗伟晶岩型锂矿的可能性,也不排除柘坪的热液型锑矿与断峰山的伟晶岩型锑矿属于同一成矿系列的可能性。柘坪Sb-Li矿床本身位于幕阜山锂铍铌钽稀有金属矿集区的外围,与断峰山伟晶岩型铌钽锂矿床相隔仅12 km,区域充分的成矿物质来源为多种类型锂矿的形成创造了条件。
In the survey area of Zheping prospecting area, Hubei Province, lithium-associated antimony ores with a certain scale has been discovered in fracture zones. Lithium is mainly filled between quartz particles in fault fracture zone in the form of cookeite, which belongs to the origin of low temperature hydrothermal filling. The mineralization of lithium and antimony is controlled by the fracture zone, and there is a general positive correlation between the contents of Li and Sb, and the metallogenic materials may originated from the Mufushan granite on the south side. This discovery not only enriches the types of lithium deposits in China, but also open a new window for prospecting of Sb-Li deposits, and provides a new entry point for the exploration of new types of lithium deposits in China. In the future, we should not only pay attention to the comprehensive evaluation of the possibility of lithium and other rare metal mineralization in antimony mineralization area, but also pay attention to the general survey and exploration of hydrothermal rare metal mineralization zone controlled by fracture zone in the deep and adjacent area by the Fangshan antimony deposit or the Zheping antimony mine. At the same time, attention should be paid to the vertical and lateral zoning of mineralization. It is not ruled out that there is hidden granitic pegmatite lithium deposit in the deep part, nor does it rule out the possibility that the hydrothermal antimony deposit in Zheping and the pegmatite-type rare metal deposits in Duanfengshan belong to the same metallogenic series related to Yanshanian granite, for the Zheping Sb-Li deposit itself is located only 12 km from the Duanfengshan Li deposit, both of them located in the periphery of the Mufushan concentration area of rare metal deposits, with the Mufushan granite contribution ore-forming metals and creating conditions for the formation of various types of lithium deposits.
