摘要
In order to constrain petrogenesis and corresponding mineralization significance,a detailed study on geochronology,mineral chemistry,major and trace elemental and Sr-Nd-Hf isotope geochemistry was performed for the quartz diorite-porphyrite and granodiorite porphyry in the Shanshangwan area of the Jiurui ore district,Jiangxi Province. The authors suggest that the contact zone between carbonate rocks of Ordovician and intrusive rocks, and the interface between carbonate strata of Ordovician and siltstone of Silurian would host high potential to form ore deposits of economic significance.
