Characteristics of Fine Grain Granitic Rock and Its Metallogenic Significance for Zhujiding Copper Deposit in
Zhujiding copper deposit is a typical copper deposit of the "Three Parallel Rivers" polymetallic metallogenic belt. The ore body is formed within the fine grain granitic rock. So far, three large-scale copper-bearing fine-grained granitic rocks have been delineated. The highest copper grade reaches around 11.42%. The results show that the fine grain granitic rock belongs to LREE enrichment and negative Eu anomalies with relative enrichment of Rb, Th and U and distinct negative anomalies of Ba, Nb, Sr, P and Ti.
