摘要
苏州富含铌钽花岗岩 (A型 )由富黑云母花岗岩和富钠长石花岗岩组成。主要副矿物为铌钽铁矿、锆石、细晶石、磷钇矿、黄玉和黄铁矿。钽元素主要形成铌钽铁矿系列单矿物 ,少量分散于长石、石英、黑云母。
Niobium and tantalum rich granite, an A type granite occurred in Yanshan Period is composed of biotite rich granite and albito rich granite in Suzhou. The main accessory minerals in the granite are columbotantalite, zircon, microlite, xenotime, topaz and pyrite. Tantalum elements constitute mainly columbotantalite series individual minerals and a few tantalum elements are distributed in feldspar, quartz, biotite, pyrite and fluorite.
