The sedimentological significance of a clastic wedge in the western basin margin of the Triassic Tethys (Iberian Range, Spain)

[EN] The Middle Triassic in the NW of the Iberian Basin consists of both carbonate and terrigenous sediments. A new sedimentary model is proposed for the clastic wedge of the Cuesta del Castillo Saudstones and Siltstones (CCSS) Formation (García-Gil, 1990), and its relationship with the Upper Musche...

Sumario:[EN] The Middle Triassic in the NW of the Iberian Basin consists of both carbonate and terrigenous sediments. A new sedimentary model is proposed for the clastic wedge of the Cuesta del Castillo Saudstones and Siltstones (CCSS) Formation (García-Gil, 1990), and its relationship with the Upper Muschelkalk carbonate Formations. The model will take account of the following characteristics: 1. Low depositional gradient being integrated in a homoclinal carbonate ramp. 2. Combined tectonic, climatic aud eustatic controis. 3. Presence of continental and shallow marine facies associations. 4. Homogeneity of textural facies. The sedimentation of the CCSS Formation took place during a relative sea level rise (high stand system tract).
