Carbonate turbidites deposited on the floor of the Palau Trench
Marine Geology, 1988Abstract Three major turbidite sequences of carbonate sediments are interbedded with a background of brown clay and monospecific diatom ooze in an 11 m long piston-core sequence recovered from the 8053 m deep flat floor of the Palau Trench. The carbonate turbidites are composed of graded sand and silt laminae derived from coral-reef lagoons, and of ...

Abstract In the central Apennines, during most of the Mesozoic, a carbonate platform shed detrital material that was discharged by turbidity currents into an adjacent basin. A sedimentological study of these detrital bodies has revealed that the depositional fan models, largely applied to siliciclastic turbidites, are not appropriate for carbonate ...

ABSTRACTIn the diagenetic history of calcareous sandstones, silicacementation and silicification may be followed by carbonatecementation and replacement and vice versa, and the change‐over from one to the other may occur more than once. This is well illustrated by calcareous and siliciclastic turbidites of the Gault Formation (Aptian to Albian) of the ...

Silurian trace fossils in carbonate turbidites from the Alexander arc of southeastern Alaska
Ichnos, 1991Early to Late Silurian (Llandovery‐Ludlow) body and trace fossils from the Heceta Formation of southeastern Alaska are preserved in the oldest widespread carbonates in the Alexander terrane. These fossils represent the earliest benthos to inhabit diverse shallow and deep subtidal environments in the region and are important indicators of early stages ...

Abstract A Paleocene carbonate sequence occurs in the southwestern part of the Sivas-Refahiye Basin, Sarkisla province (Sivas, Turkey), and is located in the northeast of Central Anatolia. Conclusions concerning the Late Mesozoic to Early Cenozoic sedimentary evolution have been derived mainly from the carbonate turbidites.

ABSTRACTIn Upper Jurassic carbonate turbidites of the Betic mountains (southern Spain), chert occurs in three morphologies: bedded chert, nodular chert and mottled chert. The last refers to a weak dispersed and selective silification which gives a speckled appearance to the rock.
