Tectonic-Lithofacies Paleogeography and Sizeable Reservoir Potential in the Early Cambrian Postrift Depressed Carbonate Ramp, Tarim Basin, NW China

open access: yesLithosphere, 2021
The carbonate ramps developed at the postrift depositional stage have become a major field of ultradeep hydrocarbon exploration. Taking the Lower Cambrian Xiaoerblak Formation in the Tarim Basin as an example, the paleotectonic framework and lithofacies ...

Synchroneity of major late Neogene sea level fluctuations and paleoceanographically controlled changes as recorded by two carbonate platforms [PDF]

open access: yes, 2000
Shallow-water carbonate systems are reliable recorders of sea level fluctuations and changes in ambient seawater conditions. Drilling results from Ocean Drilling Program (ODP) Legs 133 and 166 indicate that the timing of late Neogene sedimentary breaks ...

Facies variability of pennsylvanian oil-saturated carbonate rocks (constraints from Bashkirian reservoirs of the south-east Tatarstan)

open access: yesGeoresursy, 2020
One of the strategic ways of the old oil-producing regions is to further prospecting for potentially promising areas for hydrocarbon. One of these exploration areas is the Volga-Ural region.

Usage of microbial mats in depostional environment interpretation and sea level changes: A study of carbonate deposits of members 1 to 2 of the Mila Group (Deh-Sufiyan Formation) in Central Alborz [PDF]

open access: yesJournal of Stratigraphy and Sedimentology Researches, 2015
Carbonate deposits of members 1 to 2 of the Mila Group (Middle Cambrian) in Central Alborz that call Deh-Sufiyan Formation in this research, were studied in Shahmirzad, Tueh-Darvar, Mila-Kuh and Deh-Molla sections. These sediments were deposited in four

Experimental investigation of calcium carbonate mineralogy in past and future oceans [PDF]

open access: yes, 2011
Inorganic marine calcium carbonate formation and mineralogy varies significantly concurrent with the solution composition. During the Phanerozoic, due to oscillations in the seawater composition, this resulted in the formation of either dominantly ...

Contrasting carbonate depositional systems for Pliocene cool-water limestones cropping out in central Hawke's Bay, New Zealand [PDF]

open access: yes, 2004
Pliocene limestone formations in central Hawke's Bay (eastern North Island, New Zealand) accumulated on and near the margins of a narrow forearc basin seaway within the convergent Australia/Pacific plate boundary zone.

Modelling production ramp-up of engineering products [PDF]

open access: yes, 2010
Companies that introduce new products quickly have been shown to be better performers. The effectiveness of the new product introduction process is critical to their performance. Production ramp-up is a necessary phase of new product introduction, and

From shallow-water carbonate ramp to hemipelagic deep-marine carbonate deposition: Part 3. Lithostratigraphy and Formations of the Middle to Late Anisian Bulog sedimentary successions (Bulog Group) in the Dinarides (Bosnia and Herzegovina, Serbia, Montenegro) [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva, 2023
In the Middle Anisian the opening of the Neo‐Tethys started and this is characterized by a significant change in deposition in the whole Western Tethys Realm.

FACIES PARTITIONING AND SEQUENCE STRATIGRAPHY OF A MIXED SILICICLASTIC-CARBONATE RAMP STACK IN THE GELASIAN OF SICILY (S ITALY): A POTENTIAL MODEL FOR ICEHOUSE, DISTALLY-STEEPENED HETEROZOAN RAMPS

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2012
The Gelasian succession of the Capodarso area (Enna-Caltanissetta basin, Sicily, Italy) consists of an offlapping stack of cycles composed of siliciclastic units passing to carbonate heterozoan, clino-stratified wedges, developed from a growing positive ...

Carbonate sediment dynamics in the Abu Dhabi lagoon - implications for low-angle inner-to-middle ramp models

open access: yes, 2023
Carbonate ramps are prominent features of continental margins and intrashelf basins throughout much of Earth's history. Among the limited number of recent analogues of ancient carbonate ramps, the Persian/Arabian Gulf stands out due to its ...
