This paper discusses the enviromental characteristics of carbonaceous mudstone and mudstone (coal‐measure mudstone in short) of the Early and Middle Jurassic in the Turpan‐Hami basin, which were formed in swamps. Through the organic facies study of the coal‐measure mudstone in this area, the authors clarify that the flowing‐water swamp is the most advanced organic facies belt. Furthermore, according to the practical materials of coal‐measure mudstone in the area and with the evaluation criteria of lacustrine mudstone in the past, the authors have established the integrated symbol systems from the abundance of organic matter and the type of organic matter, which can be used in the source rock evaluation of the coal‐measure mudstone.
