Depositional, diagenetic and stratigraphic aspects of microfacies from Riachuelo Formation, Albian, Sergipe Basin, Brazil

MICROFACIES, DEPOSITIONAL ENVIRONMENT, AND DIAGENETIC PROCESSES OF THE MAUDDUD MEMBER, IN THE PERSIAN GULF

Mauddud member with the age of late Albian to Cenomanian is equivalent to the lower Sarvak formation in the southern Persian Gulf and adjacent area. In this work, microfacies, depositional environment, and diagenetic processes affected the Mauddud member in a field in the Persian Gulf are investigated. Based on the studies of available cores and thin sections of 3 wells, five types of microfaci...

Systematic of Albian - Cenomanian Gastropods and Bivalves from the Kazhdumi Formation, Zagros Basin

The Albian- Cenomanian (Kazhdumi Formation) sediments from northeast of Shiraz, Zagros Basin, represents a carbonate sedimentary succession and contain diverse gastropods and bivalves. Detailed studies on 80 samples of invertebrate macrofauna on two stratigraphic sections led to recognized 2 species and 5 genera of gastropods and 7 species and 13 genera of bivalves assemblages. The abscence of ...

87Sr/86Sr DEPOSITIONAL AND DIAGENETIC CHRONOLOGY FROM ALTERED SKELETAL MATERIAL

A new fossil caridean shrimp (Crustacea: Decapoda) from the Cretaceous (Albian) of the Romualdo Formation, Araripe Basin, northeastern Brazil.

A new fossil caridean shrimp, Kellnerius jamacaruensis n. gen. n. sp., of the early Cretaceous (Albian) from the Romualdo Formation, Araripe Basin, northeastern Brazil is described and illustrated. The new species is compared to known fossil palaemonids found in Brazil. Kellnerius jamacaruensis n. gen. n. sp. is easily differentiated from the other palaemonids by a rostrum with 5 spines, an enl...
