Distribution and genesis of the Maokou Formation dolomite in Fengdu-Shizhu area, eastern Sichuan Basin [PDF]

open access: goldEnergy Exploration & Exploitation
To investigate the development laws and genesis of the Maokou Formation dolomite in the Fengdu-Shizhu area, we analyzed core, thin section, logging, and geochemical data, and obtained the following understandings: 1.

Effect of Fe Content on Raman Spectral Characteristics of Dolomite

open access: yesYankuang ceshi, 2023
BACKGROUNDDolomite is a common carbonate mineral in sedimentary rocks, and dolomite rock serves as an important reservoir rock for oil and gas. However, the production of synthetic dolomite under normal temperature and pressure is not yet possible, the ...

Dolomitization evolution and its effects on hydrocarbon reservoir formation from penecontemporaneous to deep burial environment

open access: yesPetroleum Exploration and Development, 2022
Aiming at the scientific problem that only part of dolomite acts as dolomite reservoir, this paper takes the multiple dolomite-bearing formations in the Tarim and Ordos basins, NW China and Sichuan Basin, SW China as the study object, by means of mineral

Modern dolomite formation caused by seasonal cycling of oxygenic phototrophs and anoxygenic phototrophs in a hypersaline sabkha

open access: yesScientific Reports, 2021
The “Dolomite Problem” has been a controversy for over a century, owing to massive assemblages of low-temperature dolomite in ancient rocks with little dolomite forming today despite favorable geochemical conditions.

Clumped‐Isotope Geothermometry and Carbonate U–Pb Geochronology of the Alta Stock Metamorphic Aureole, Utah, USA: Insights on the Kinetics of Metamorphism in Carbonates

open access: yesGeochemistry, Geophysics, Geosystems, 2021
To assess thermal and kinetic influences on atomic mobility and mineral (neo)crystallization, clumped‐isotope abundances of calcite and dolomite were measured alongside dolomite cation ordering and U–Pb dates, across metamorphic grade within the c. 35–30

Formation mechanisms and development models of dolomite reservoirs in Ordovician Yingshan Formation in Shunnan area, Tarim Basin

open access: yesShiyou shiyan dizhi, 2020
The dolomite reservoirs of the Ordovician Yingshan Formation in Shunnan area of the Tarim Basin have a great oil and gas potential. However, the genesis of different types of dolomite reservoirs is still subject to debate.

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

open access: yes, 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 ...

Discriminating cool-water from warm-water carbonates and their diagenetic environments using element geochemistry: the Oligocene Tikorangi Formation (Taranaki Basin) and the dolomite effect [PDF]

open access: yes, 2004
Fields portrayed within bivariate element plots have been used to distinguish between carbonates formed in warm- (tropical) water and cool- (temperate) water depositional settings.
