| 摘 要： | 花岗伟晶岩型铀矿是目前发现的一种新类型铀矿。这种矿床的晶质铀矿是从花岗岩浆分异出来的富铀岩浆中结晶而成的。下元古界秦岭群是成矿有利环境,韧性剪切带是控岩控矿的主要构造。这种类型铀矿在商丹三角地区的远景是可观的。

| Abstract: | The granite-pegmatite-type uranium deposit is a new type of uranium deposit which has been recently discovered. Uraninite in this type of deposit is crystallized by U-rich magma which is differentiated from granitic magma. The Qinling Group of Lower Proterozoic is an advantageous environment for metallogenesis and the ductile shear zone is a major structure to control rocks and ores. It is held that the prospect of the type of uranium deposit in Shangxian-Danfeng triangle area is considerable. |
