Abstract :

The Chamanbid Formation is a sedimentary unit of kopet Dagh basin related to the middle Jurassic and late Jurassic period. From the petrology view point, this Formation mainly consists of slim to medium micritic limestone layer with mid – layers made of lime shale and light leucocratic gray marls. The base of Chamanbid Formation in Gujki section has been covered with young Fluvial and can not be identified, but at the top it ends to the limestone of Mozduran Formation with a similar and gradual move. The thickness of Chamanbid Formation in Gujki section was determined 201 ms and according to the lithologic characteristics, it can be divided to 4 main lithostratigraphi units. This unit which includes shale and limestone alternation, slim to thick layer fossiliferous limestones, shale, sandstone and alternation of shale and onchoied fossiliferous limestones, has been located in a deep to shallow marine environment.
