ABSTRACT : The transportation mechanism and the dcterminaton of the sedimentation environments of the stand-size elastics earn he carried, out `through examination of their certain gedimentological characteristics such as. sedimentary structures, fossil contents and sfgnilar properties. However, these procedures im sequences thai do not outcrop, or do mot have tlie above properties, can. only be possible by ecrtain textural meliw&, In the present paper, ax© introduced four` sedinoentological-textaral methods that can be applied especially to thin sections, and the transportation mechanism and the determination of the -sedimentary environments for the elastic material forming the séquence- are presented.
