| 英文摘要 | Concealed rock mass is important for a hydrothermal deposit prospecting. There are a lot of methods to look for concealed rock; the best of them is geophysical prospecting method (magnetic method, electric method, gravity, earthquake, etc.). Magma thermal field method is dedicated to find concealed rock. Magma thermal field method is a kind of geophysical methods, which to perceive the difference of temperature field, its biggest advantage is no multiple solution. It based on the magma thermal field theory; its means is a variety of methods to restore the ancient temperature field. This paper introduces the five of these methods, contact metamorphic zone method, coal quality and coal rank method, illite crystallinity method, conodont alteration index method and vitrinite reflectance method. Contact metamorphic zone is the concrete and direct expression of magma thermal field; the traditional contact metamorphic zone was limited (generally less than 1 km). However, if considering the very low grade metamorphism, it will greatly extend the scope of the contact metamorphic zone (up to 6 8km). Coal quality and coal rank method is applied very adept in coalfield geology department. Illite crystallinity, conodont alteration index and vitrinite reflectance method is very important in the study of very low grade metamorphism. In the above methods, the author recommends the vitrinite reflectance method, which is simple, accurate, applicable, economic and fast. Compared with geophysical exploration methods, this method has many advantages, but also has its limitations. If it can be transplanted from coal and oil geology department into petrology and mineral deposits department, and couple it with magnetic method, electric method and gravity method, which can improve the effect of searching for concealed rock, advancing the prospecting practice of the deep concealed deposits. |
