| Abstract: | All the early, late Jurassic end early Tertiary terrestrial coal-bearing formations in Northeast China consist two coal-bearing zones separated by thick mu-dstone beds in the middle of the formations.These coal-bearing formations represent two different paleogeographic types, one is intermountainous(cr piedmont) type of esrly and late Jurassic and mother is alluvial(or flood)plain type of Tertiaary.Althouh the coal basins are different in geological age and setting, they resemble in sedimentary sequencys,rock association end the assembage of coal ceams. The resemblance in their sedimentary facies may be summarized as the following sedimentary sequence pattern:1st stage, piedmont-fluvial facies2nt stage. paludal(peat swamp)-lacustrine facies3rd stage, lacustrine facies4th stage. lacustrine-paludal(peat swamp)facies5th stage; paludal-fluvial faciesThe 2nd and the 4th stages provided favourable paleogeographic environments and structural conditions for coal accumulation. |
