Genesis and dolomitization of “Khali” powder crystal dolomite in Triassic Jialingjiang Formation, Moxi gas field, central Sichuan Basin, SW China

open access: yesPetroleum Exploration and Development, 2014
Taking the B bed of the second submember of the second member of Triassic Jialingjiang Formation in Moxi gas field as an example, the basic characteristics and controlling factors of the “Khali” powder dolomite reservoir is analyzed systematically, and ...

Petrography and isotope-geochemistry of the Bayandor Formation dolomites at the type section, south-west of the Zanjan [PDF]

open access: yesJournal of Stratigraphy and Sedimentology Researches, 2019
The Late Precambrian Bayandor Formation has a thickness of 402 m and consists of shale and sandstone with dolomite interlayers (with a thickness of about 2 to 8 m) in the type section of the south-west of Zanjan. Based on fieldwork studies lithofacies of

Comparison of the Late Triassic carbonate platform evolution and Lofer cyclicity in the Transdanubian Range, Hungary and Pelagonian Zone, Greece [PDF]

open access: yes, 2009
For comparative studies of Upper Triassic cyclic platform carbonates, the Transdanubian Range (Hungary) and the Pelagonian Zone (Greece) were chosen. Paleogeographically they represent two distant segments of the passive margin of the Neotethys Ocean ...

Discussion of multiple formation mechanisms of saddle dolomites—Comparison of geochemical data of Proterozoic–Paleozoic dolomites

open access: yesEnergy Exploration & Exploitation, 2018
As important gas-bearing strata, Proterozoic–Paleozoic marine carbonate successions in the Sichuan Basin have experienced a long diagenetic history and multiphase hydrothermal activities.

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.

Effects of Deep Fluids on Middle Permian Dolomite of the Western Sichuan Basin

open access: yesFrontiers in Earth Science, 2022
Deep fluid activity is closely related to carbonate reservoir transformation as well as oil and gas accumulation. The large-scale deep fluid activity caused by Emeishan large igneous province (ELIP) brought a lot of deep material and energy to Sichuan ...
