The effect of meteoric water on the very fine crystalline dolomite reservoir in the shallow burial zone: A case study of the Ma55 submember of Majiagou Formation in Ordos Basin

Frontiers in Energy Research, 2023
The meteoric water has obviously changed the physical properties of dolostone reservoirs in the vertical vadose zone and the horizontal phreatic zone, but its influence on the dolostone reservoirs in the shallow burial zone beneath the phreatic surface ...

Similarities and differences in the dolomitization history of two coeval Middle Triassic carbonate platforms, Balaton Highland, Hungary [PDF]

, 2014
Dolomitization of platform carbonates is commonly the result of multiphase processes. Documentation of the complex dolomitization history is difficult if completely dolomitized sections are studied.

Controls on Cyclic Formation of Quaternary Early Diagenetic Dolomite [PDF]

, 2018
The origin of sedimentary dolomite and the factors that control its formation within the geological record remain speculative. In most models, dolomite formation is linked to evaporative conditions, high water temperature, increasing Mg/Ca ratio ...

Characteristics and genesis of dolomite in the lower Cambrian Xiaoerbulake Formation of the western Tarim Basin, China

Frontiers in Earth Science, 2023
The Lower Cambrian Xiaoerbulake Formation consist of thick dolostones which are high-quality hydrocarbon reservoir in the western Tarim Basin, but the origin of dolomite is still controversial, which lead to poor understanding to the origin of reservoir ...

Early dolomitization of platform carbonates and the preservation of magnetic polarity [PDF]

, 1993
Results from a combination of techniques are presented to evaluate the nature of magnetization in shallow-water platform carbonates which have undergone recrystallization during early calcification and dolomitization. Magnetic grain separates, coercivity
