Abstract:

The gold mineralization characteristics of granitoid-related is an important type of gold mineralization in Nishan ore segment.Through the study of plagioclase granite porphyry veins and its ore body,probing into the basic features of such gold ore,we conclude that the mineralization type is controlled by Yanshanian grantie.The distribution of rock body in the region is closely related to the structure.Under the control of sunder,the veins with generally small scope and size,have near east-west strike,mostly veined output,and a small amount of rock strains.Rock types in the region is acidic rocks,plagioclase granite porphyry.This article focuses on the mineralization and alteration of the plagioclase granite porphyry and gold content,and come to the conclusion that mineralization of 508 vein in Nishan ore segment contains the process of mineral substance migration and enrichment.

Key words: Mineralization characteristics, Metallogenic regularity, 508 vein mineralization, Nishan ore segment, Gansu Province
