The Upper Cretaceous (?Santonian) Aitym Formation in the central Kyzylkum Desert, Uzbekistan, produced remains of a cimolodontan multituberculate (Uzbekbaatar wardi), a spalacotheriid symmetrodont (cf. Shalbaatar sp.), a deltatheroidan (cf. Deltatherus sp.), possibly the asioryctithere aff. Daulestes sp., possibly two zalambdalestids (Kulbeckia sp. cf. K. kulbecke and aff. Kulbeckia sp.), two s...

A species of the beryciform fish genus Hoplopteryx, collected from rocks of Turonian Age in the Pool Creek Member of the Carlile Shale Formation, is described from the fossil record of South Dakota for the first time. The specimens are part of the Bishop Collection, now housed in the repository at the South Dakota School of Mines and Technology (SDSM). Despite their geographic distance from the...

New Ar-Ar muscovite and Rb-Sr biotite age data in combination with structural analyses from the Apuseni Mountains provide new constraints on the timing and kinematics of deformation during the Cretaceous. Time-temperature paths from the structurally highest basement nappe of the Apuseni Mountains in combination with sedimentary data indicate exhumation and a position close to the surface after ...

Quantification of Milankovitch orbital cyclicity within ancient strata has become a principal tool for refinement of the geologic time scale. However, accurate characterization of the orbital signal in deep time paleoclimate records is commonly challenged by inadequate radiometric time constraints for calibration of the spatial rhythms to temporal periods. This problem can potentially introduce...

The Mishrif reservoir (Cenomanian - Turonian) in the Z, H, B and N oilfields southern Iraq was investigated to clarify how nickel, vanadium, asphaltene, NSO sulfur content affect crude oil quality. GC-Mass ICP-MS analyses were used provide fruitful hydrocarbon results. Classification of based on API gravity broadly indicates oil's density general properties. Typically, lighter oils are easier r...

The present work focuses on the upper Cretaceous (Cenomanian-early Campanian) carbonate successions in selected wells from northwestern Iraq. These are represented by Gir Bir Turonian), Wajna (late Santonian) and Mushorah (early Formations. succession has affected early burial near-surface, unconformity-related deep diagenesis cementation, neomorphism, dolomitization, dedolomitization, silicifi...

The Mishrif Formation is an important succession that was deposited during the Cenomanian–Early Turonian. More than 79 thin sections of core in addition to well log data for from 2 boreholes within E oilfield (E-1, and E- 2) were used determine different associations facies interpret depositional environment Formation. Six major microfacies diagnosed Formation, Mudstone, Wackestone, Packstone, ...
