THE OCEURENCE PATTERNS OF PETROGRAPHIC FACIES AND PALAEOGEO GRAPHY AND OF LATE TRA ASSIC SEAMS IN YUNNAN PROVINCE

  • By compilingthe paleogeo raphic maps of petrographic facies of several late Triassic periods in YunnanProvince. the paper analysed and approachedthe occurence patterns of the late Triassin seams,making suggestions for classification andcoal-bearing potential of the Late Trissic coal-forming periods in the province.
