摘要
苏州善安浜钽铌矿床产于苏州花岗岩向北延伸呈局部隆起的钠长石花岗岩中,上钽下铌特征十分明显,由上而下分为3个矿体。其中Ⅰ矿体是主矿体,为钽矿体,伴生铌;Ⅱ矿体为铌矿体,伴生钽;Ⅲ矿体为铌矿体。主要有用矿物为铌钽铁矿,呈粒间嵌存于钠长石花岗岩基质中,占总量的95.04%。铌钽铁矿的嵌存关系与云母、长石最为密切,占93.99%,极少数与锆石连生。
Shananbang tantalum-columbium deposit lies in the west of Suzhou City. Tantalum-columbium deposit was occurred in albite granite of the north extending portion of Suzhou granite with distinct features of tantalum above and columbium below and three ore bodies. In which, No. 1 is the main orebody, tantalum, associated with columbium; No. 2 is columbium, associated with tantalum; No. 3 is columbium orebody. The main useful minerals are columbium-tantalum-iron ores inlaid within albite granite matrix in granular, accounting for 95.04% of total amount.
