The Geza arc is an important part of the Yidun Island arc in Sanjiang tectonic-magmatic rock belt. It is located at the southern tip of the Yidun island arc belt. It is an important copper-lead-zinc polymetallic metallogenic belt and Indosinian porphyry copper belt in the western region of China. Pulang porphyry copper deposit is a typical representative of the Indosinian porphyry copper deposits. Based on the previous studies, the big data analysis technique was used to make a contrastive study of the ore-forming related granite in Pulang porphyry copper deposit and the global adakite. As a result, 506 element combinations and 127765 overlap ratios were obtained. The result shows that the geochemical data of the Pulang porphyry are basically overlapped with the global adakite, and have similar characteristics with the global adakite. However, the Cu, Mo, Pb and Zn metallogenic elements are significantly higher than those of the global adakite, and although the ratios of REE and Ga to the major element are in the range of the global adakite, they show the phenomenon of an end member in the global adakite. In addition, the adakite associated with porphyry copper deposits are distributed partially in the global adakite, and some or most of the data are out of the distribution range of the global adakite, and with characteristics of low Sr/Cu, Ta/Cu, Al/Mo, Mn/Zn, Mn/Cu, Mn/Mo and Hf, K, Ti, P, Co, Th, Ca/Cu. The farther the data points deviate from the global adakite range, the stronger the alteration and mineralization are, and the closer the relationship with copper and molybdenum mineralization is. The geochemical data mining results can be used as a prospecting indicator, which can provide a new scientific basis for the geological prospecting of the deep and periphery of the Pulang copper deposit.
