영문 초록

Ogbang scheelite deposit imbedded in amphibolite of unknown ages was believed, by the previous workers, to be of pegmatite vein. The vein material is composed mainly of plagioclase (albite and oligoclase) and minor amount (less than 5 to 10% each) of hornblende, biotite and quartz. Orthoclose and tourmaline are accompanied in few places and scheelite and minor amount of fluorite, are the ore minerals. On the basis of mineralogical constituents of the vein, vein structures, mode of occurrence of th vein and gradational contact between veins and amphibolite, the present writer conclude that the deposit was formed by segregation from the parent basic igneous rock of amphibolite. The main portions of the deposit were formed by intrusion of ore solution into already solidified amphibolite ager being segregated in deeper horizone, whereas the minor portion by segregation of ore solution in situ.
