  • The Middle and Lower Jurassic with thick coal seam is widely distributed in Northwest China.The statistical and measured organic macerals of coal indicated that high content of hydrous desmocollinite is of gene-ral phenomenon with its average ratio to total organic maceral up to 18% in the region although content of exinite in coal usually is not high.Hydrous desmocollinite and exinite in coal are the principal material for hydrocarbon generation.Based on comparison coefficient of organic geochemical parameters of coal,hydrocarbon generating potential of coal in the area was evaluated.It was pointed out that hydrocabon generating potential of coal was excellent in many basins in the area,where was favourable for petroleum exploration.
