TLDR
In this article, two fields are considered, that illustrate divergent and contrasting modes of dolomite stabilization despite initial similarities in facies and textures, showing that dolostones in the Dunvegan Field and the Mount Head Formation of the Shell Waterton Field have a very unique set of relatively non-reactive physico-chemical conditions during burial.About:

Incidence and Importance of Tectonics and Natural Fluid Migration on Reservoir Evolution in Foreland Fold-And-Thrust Belts
François Roure,Rudy Swennen,F. Schneider,J. L. Faure,H. Ferket,N. Guilhaumou,K. Osadetz,P. Robion,Veerle Vandeginste +8 more
TL;DR: In this paper, a structural-petrographic-magnetic-basin modeling case study in numerous foreland fold-and-thrust belts provided key information on the critical parameters and processes controlling reservoir evolution from the end of the passive margin phase to the post-orogenic collapse of the tectonic pile.

Multi-scale characterization of unconventional tight carbonate reservoir: Insights from October oil filed, Gulf of Suez rift basin, Egypt
TL;DR: In this article, the pore system is a combination of depositional and diagenetic processes and the dominant porosity types include fracture, interparticle, intra-particle and moldic porosity; NMR indicates mesopores to macropores, and geochemical analysis indicates a self-sourced unconventional reservoir based on its organic richness characteristics unconventional resource opportunity as tight carbonate reservoir, and it is a potential conventional resource.

Multiple dolomitization and later hydrothermal alteration on the Upper Cambrian-Lower Ordovician carbonates in the northern Tarim Basin, China
TL;DR: In this article, the origins of matrix and cement dolomites and other diagenetic minerals are interpreted on the basis of petrography, isotopic geochemistry (O, C and Sr), and fluid inclusion micro-thermometry.

A unique lacustrine mixed dolomitic-clastic sequence for tight oil reservoir within the middle Permian Lucaogou Formation of the Junggar Basin, NW China: Reservoir characteristics and origin
TL;DR: The Lucaogou Formation is a sequence of mixed carbonate (mainly dolomites) and terrigenous clastic sediments that were deposited in a highly saline environment as discussed by the authors.

Multistage hydrothermal dolomites in the Middle Devonian (Givetian) carbonates from the Guilin area, South China
TL;DR: In the Guilin area, South China, a number of dolomite cements were found to be precipitated from high temperature hydrothermal fluids, derived from underlying siliciclastic deposits, and were associated with more intense hydrothermastic events during Permian-Early Triassic time, when the host dolostones were deeply buried as mentioned in this paper.

Classification of dolomite rock textures
Duncan F. Sibley,Jay M. Gregg +1 more
TL;DR: In this article, the authors classified planar and nonplanar dolomite textures according to crystal size distribution and crystal boundary shape, which is largely descriptive but carries genetic implications because size distribution is controlled by both nucleation and growth kinetics.

Strontium Isotopes in Seawater through Time
TL;DR: In this paper, the decay energy of isotope 87 (87Srp) was investigated and the recommended decay constant for 87Rb is 1.42 x 10-11 yr-I (Steiger & Jager 1977), and its half-life T is therefore 48.8 Gyr.

The Origin of Massive Dolomite
TL;DR: Most dolomite forms as a calcium-rich and/or poorly ordered metastable phase when seawater is actively circulated through carbonate sediments as mentioned in this paper, and the extensive circulation which is necessary for massive dolombization can be caused by density or elevation head, or by convection induced by geothermal heat.

Dolomitization; a critical view of some current views
TL;DR: In this article, it is suggested that, in general, contemporaneous dolomite will form at low temperatures only by direct precipitation, a mechanism that requires special conditions of highly super-saturated waters of high Mg/Ca ratio and elevated CO 3 -HCO 3 concentrations.

Dolomitization: A Critical View of some Current Views: PERSPECTIVES
TL;DR: The main models in vogue today for dolomitization are the mixing zone and the sabkha models Despite the wide acceptance of these models, there has been little critical assessment of their validity as mentioned in this paper.
