Anhui Tongling, Tian Diagenesis And Mineralization Mechanism And Concealed Orebodies Predictive Analysis

Conducted by Diwa theory and analysized by geological synthetic method, the paper give a whole research to the metallogenetic geotectonic background and its evolution, regional ore-controlling factors, mineralization regularities in Tongling Area and to the geological mineral-formation conditions, the ore deposit genesis, the rock-forming and ore-forming mechanism in FengHuangShan mine field of Tonfling Area. Baesd on these, the paper has researched the location pediction for concealed orebodies of FengHuangShan copper ore deposit, concluded the regularities of prediction and pointed out geological synthetic exploring model combining the geophysical and structral geochemical characteristics.Through the research, the paper gains some new knowledge on: CD Conducted by Diwa theory, the paper has divided the geotectonic evolution into four stages including Pre-geosynclinal stage, Geosynclinal stage, Platform stage and Diwa stage, and has concluded the history of the geotectonic evolution of Tongling Area. (2) The paper has systemly analysized the ore-controlling factors and the mineralization regulaities of region and geological mineral-formation conditions of mine field and concluded geological exploring criteria combination. (3)Through the research of the rock-forming mechanism to the compound rockbody of FengHuangShan, the paper has pointed out that granodiorite and quartzmonzonite, which consist main parts of the compound rockbody, are the results of different activities. The quartzmonzonite is the result of the latter stage, the granodiorite is the result of the earlier stage. The obvious saltative relationship shows between the granodiorite and quartzmonzonite. (4)For the first time to determine the quartzmonzonite as the mineral-bearing porphyric rockbody. Based on this, combing the fluid characteristics, discussed the dynamic mechanism of mineral formation and pointed out a new view that FengHuangShan copper ore deposit belongs to the compound genesis of skarn-porphyry. (5)On the basis of the synthetic analysis of geological, geophysical and strucural geochemical information, the paper has researched the location prediction for concealed orebodies of FengHuangShan copper ore deposit, concluded the regularities of prediction and pointed out geological synthetic exploring model.
