The Cehegín Formation (Ladinian) is defined as a formal lithostratigraphic unit to characterize the Muschelkalk facies deposited on intermediate-external area of the southern Iberian continental margin. This formation consists of dark limestones and marly limestones. Two main members can be distinguished in this formation. In the lower member, two o three massive carbonate thick beds appear with bedded marly limestone intercalations. The upper member consists of a more marly succession of carbonate beds with burrows and intercalations of bioclastic limestone. Pot and gutter casts are frequent in the lower member, and tempestites occur mainly in the upper member. The sediments of this formations are interpreted as epicontinental marine deposits. The holostratotype, parastratotypes and hypostratotype which characterize this formation in the Betic Cordillera are described.
