Dashui gold deposit is one of the renowned superlarge gold deposits, numerious research has been done on its geochemical characteristics.The study focuses on correlation between all the data from all geological bodies using various geochemical means. Comparison of the largest orebody to other orebodies shows that they all show great differences in six geological factors such as country rock in the topwall and footwall, grade, dipping, length and depth, suggesting that main orebodies formed in a special environment. Orecontrolling variables such as length, thickness,depth and dipping are interrelated with dips ranging from 20 to 320. There is no distinct correlation among dipping angle, grade and other variables, suggesting that the deposit is not undirectly controlled by epizonal orecontrolling factors but related to local ringlike or taperlike structures resulted from magmtic intrusion and hydrothermal activities. Compared to previous results, country rocks around largetonnage orebodies are characterized by structural breccia or altered breccia, which indicates filling genesis. Mediumscale orebodies resulted from hydrothermal metasomatism. Smallsized orebodies are probably related to sedimentation. Spatically, various mineralizations are subject to the law of isospatial metallogenesis. The relation of tonnage to grade in the deposit is subject to exponential function, rather than power function.
