| Abstract: | By comprehensive geophysical interpretation in Song -liao basin, twenty six faults (sixteen lithosphere faults, five crust faults and fifteen basement faults) can be determined , also, five types of lithology in the basin have been deduced, they are: (1)the precambrian metamorphic rocks; (2)the mylonite; (3)the lower palaeozonic metamorphic rocks; (4)the permian shallow metamorphic rocks;(5)the granite . The above research results provide the important information about the evolution and oil-gas-bearing properties of the basin. |
