Spit-platform temperate carbonates: the origin of landward-downlapping beds along a basin margin
Lower Pliocene temperate carbonates exhibit landward-downlapping beds at the southern margin of the Carboneras Basin in south-eastern Spain. This rarely documented stratal geometry resulted from the accumulation of bedded bioclastic carbonate sand and gravel by longshore currents along a spit platform located a few hundred metres from the palaeoshoreline. The top of the spit platform was covere...
متن کاملTectonosedimentary evolution of the basins in Central Alborz, Iran
Evidence of at least ten different tectonic- controlled sedimentary basins can be recognized in the central part of the Alborz Mountains in the Middle part of the Alpine-Himalayan belt. They formed from Neoprotrozoic to recent time as the results of the relative plate motion in southwest of Asia in Tethyan realm. The basins include: (1) Prototethys Late Neo-Proterozoic to Early Ordovician epi-c...
متن کاملMacrofaunal Response to the End-triassic Mass Extinction in the West-tethyan Kössen Basin, Austria
Bivalves are the most common macrofauna present in marine sequences spanning the end-Triassic mass extinction and document the initial ecological response to the crisis. In the west-Tethyan Kössen Basin, marine bivalves occur within distinctive low diversity episodic shell beds at the time of initial crisis and d13C minimum, and continue for 1 m (,,20 kyr) upward into the peak extinction phase ...
متن کاملPaleoenvironment, Biostratigraphy and Sequence stratigraphic studies of the Permian-Triassic boundrary of the offshore Persian Gulf, Iran: using an integrated approach.
Four supergiant and numerous giant gasfields have been discovered in the Southwest Iran which produce from Permian-Triassic carbonates belong to the upper member of Dalan Formation and Kangan Formation. In this research a detailed biostratigraphic, microfacies and sequence stratigraphic study of the late Middle Permian to Triassic successions was undertaken from 850 thin sections prepared from ...
