...Degao Zhai; Anthony E. Williams-Jones; Jiajun Liu; Stylianos F. Tombros; Nigel J. Cook Abstract The Sandaowanzi gold deposit in the Great Hinggan Range metallogenic belt, northeast China, is unusual because the mineralization takes the form of Au- and Ag-bearing tellurides. This mineralization...

... of the role and importance of magmatic fluids in the formation of bonanza ores remains limited. To address these concerns, we conducted Cu isotope analyses of chalcopyrite, which coexists with Au-Ag-tellurides in the Te-rich Sandaowanzi deposit located in northeastern China, as well as ore-bearing quartz...

Homogenization temperatures and salinities of fluid inclusions from the Sandaowanzi, Yongxin, Dong’an, and Tuanjiegou deposits in the North Heilongjiang Belt, NE China. Representative samples overlay with R/RA from the same sample. Symbol shape with color line is for data points from each deposit. Color filling is the stage. Shape size is R/RA value. Gray field and colored lines encompass data from different deposits and are determined by 2D density contours. Secondary fluid inclusions (FIs) are formed when fluids are trapped after the crystal growth is complete. (Color online.)

Lead isotope evolution model for lead sources in epithermal Au-Ag deposits (North Heilongjiang Belt, NE China). Colors of characters, numbers, and lines: Sandaowanzi = red; Yongxin = yellow; Dong’an = green; and Tuanjiegou = blue. The model age of both lead sources is based on the maximum and minimum ages for each deposit. Values of μ1max and μ1min are calculated values from lead evolution models. μ1 corresponds to the 238U/204Pb ratio of mantle (7.192; Tatsumoto et al. 1973) and lead source; t1max and t1min correspond to the age of crust formation for lead sources 1 and 2 in each deposit, respectively.
