| 英文摘要 | Granite and continental tectonic and their relationship with mineralization is two of the most widely discussed fields among earth sciences, for hundreds of years, it has made great achievements and great progress of petrology and mineral deposits. However, there are still problems in basic theory of granite. Two misunderstandings in granite researches: (1) granite without its own independent theory, granite is mainly follow the theory of basalt, such as fractional crystallization, the magma mixing, magma source, tectonic environment, etc. (2) the theories of granite is mainly the application of plate tectonic theory, and plate tectonic theory is not suitable for the study of continental granites. Plate tectonic theory is a good theory, but the plate tectonic theory can only solve the problems of the ocean and the edge (Andes), can't solve the problems of the continent itself. Granite is mainly located in the continent, very few in the ocean. Fractional crystallization of granite is a major issue of the academic debate, this article points out that the granite fractional crystallization is impossible, is analyzed from the field, the microscopic relations, theoretically, the methodology and the logic of syllogism. Magma mixing is another issue, and the author believed that the mixture of granite mainly occurs in the bottom of the earth's lower crust, rather than in the process of granite emplacement and rising. Magmatic emplacement, leaving the source area and the temperature drop, is not conducive to the magma mixing. Granite is mainly physical mixing (basalt is a chemical mingling). At present, geochemical research is the most valued in the granite field. Granite geochemical research should focus on solving two problems: (1) solving questions raised by production; (2) deal with the problem raised by geochemistry their own development. Granite geochemical research is lost with leaving this two. About granite and continental tectonic problems, the author thinks that, granite should be divided into the ocean and the continental series. Located in the edge little affected by the subduction of the ocean and the sea is the ocean series; Located in the continental interior series belong to the continental series. The granite tectonic environment discrimination diagrams only apply to the ocean series. Geodynamic meaning of continental series is not a tectonic environment or the environment, but the temperature and pressure conditions at the bottom of the earth's crust. We have put forward the classification by the Sr-Yb, suited to explain geodynamics of continental series. The relationship between granite and the mineralization is a major issue of the academic debates, which focuses on two issues: (1) the magma is how formed? The magma derived from where? (2) the fluid is how formed? How fluid to rise? In order to discuss the above issues, this paper mainly discussed the magmatic thermal field theory. Using this theory to explain the mineralization related to granite, including a variety of related to the magmatic metamorphic sedimentary hydrothermal mineralization and magmatic thermal field's influence on coal and oil and gas, etc. On this basis, put forward the concept of "metallogenic combination" related to granite. The most important meaning of magmatic thermal field is probably explain why a large magmatic activity related to large-scale metallogeny, points out that 1 + 1 > 2 effect caused by the magma activity. |
