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

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.

Massive dolomitization driven by MgSO-rich seawater and its effects on thermochemical sulfate reduction, Upper Permian Changxing Formation, northeastern Sichuan, China

open access: yesEnergy Exploration & Exploitation, 2022
Massive dolostones replacing build-ups and containing H2S of thermochemical sulfate reduction (TSR) origin occur in the Upper Permian reef and bank deposits, northeastern Sichuan, China, despite the absence of gypsum or anhydrite deposits, which are ...

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 ...
