Geology, geochronology, fluid inclusion and H–O isotope geochemistry of the Luoboling Porphyry Cu–Mo deposit, Zijinshan Orefield, Fujian Province, China

Application of improved bi-dimensional empirical mode decomposition (BEMD) based on Perona–Malik to identify copper anomaly association in the southwestern Fujian (China)

“…Previous studies indicate that Ag, As, Au, Cd, Mo, Pb, Sb, Zn, and Sn have strong spatial correlations with Cu polymetallic mineralization in the study area (So et al, 1998;Ruan et al, 2006;Jiang et al, 2013;Zhong et al, 2014). These 10 geochemical variables were integrated using PCA to reduce the number of variables and obtain relatively few uncorrelated variables for accounting for the most information of data.…”

“…1); the eastern area of the fault zone contains a few scattered mineral deposits (Wu, 2002;Ruan et al, 2006;Zhao et al, 2013;Jiang et al, 2013;Zhong et al, 2014). Porphyry-type and volcanicsubvolcanic hydrothermal-type Cu polymetallic deposits are the most two important types in the study area (Shi et al, 1991).…”

“…The Zijinshan volcanic-subvolcanic type Cu-Au deposits, located at the intersection of the NW oriented Shanghang-Yunxiao fault zone and the NE oriented Xuanhe anticlinorium in the NE margin of the Shanghang Meso-Cenozoic volcanic basin, is the largest one in southwestern Fujian and related to the late Yanshanian acidic subvolcanic and volcanic formations (Ruan et al, 2006;Zhao et al, 2013;Jiang et al, 2013;Zhong et al, 2014). The major Cu ore body is located outside of the volcanic edifice, which penetrates the early Yanshanian granite along the NW trending and is controlled by NW oriented cryptoexplosive breccia and dacite porphyry belts.…”

Geochemistry and fluid characteristics of the Dalli porphyry Cu–Au deposit, Central Iran

“…Given that the IIIAB, IIIA, and IIIB inclusions have approximately the same homogenization temperature range (Fig. 9a), but homogenize in different ways seems trapping of NaCl-saturated immiscible fluids and boiling event was likely to have occurred (Siahcheshm et al, 2014;Zhong et al, 2014). Moreover, the association of saline inclusions with liquid-rich and vapor-rich fluid inclusions may indicate that some of these inclusions are formed in an immiscible system and/or boiling.…”

Genesis of the Zhijiadi Ag-Pb-Zn Deposit, Central North China Craton: Constraints from Fluid Inclusions and Stable Isotope Data

“…The estimation of trapping pressure and mineralization depth are of great significance for targeting of deep-seated blind orebodies and distinguishing deposit type [57]. The existence of abundant C-type and W-type FIs in the Zhijiadi deposit makes it possible to obtain the trapping pressure and mineralization depth [58,59].…”
