TLDR
In this article, the authors explore the relative importance of secondary porosity due to thermochemical sulphate reduction (TSR) during deep burial diagenesis and find that new secondary pores result from the dissolution of anhydrite and possibly from dissolution of the matrix dolomite.About:

Petroleum reservoir quality prediction: overview and contrasting approaches from sandstone and carbonate communities
Richard H. Worden,P. J. Armitage,Alan R. Butcher,J. M. Churchill,A. E. Csoma,Cathy Hollis,R. H. Lander,Jenny E. Omma +7 more
TL;DR: In this article, the authors introduce basic concepts, analytical and modelling techniques and some of the key controversies to be discussed in 20 research papers that were initially presented at a Geological Society conference in 2014 titled ‘Reservoir Quality of Clastic and Carbonate Rocks: Analysis, Modelling and Prediction’.

Huan Cui,Kouki Kitajima,Michael J. Spicuzza,John H. Fournelle,Adam Denny,Akizumi Ishida,Akizumi Ishida,Feifei Zhang,John W. Valley +8 more
TL;DR: In this article, the authors used secondary ion mass spectrometers (SIMS) to estimate the genesis of sedimentary pyrite using combined petrography and micrometer-scale δ34S measurements by SIMS.

Dolomitization history and porosity evolution of a giant, deeply buried Ediacaran gas field (Sichuan Basin, China)
Yongjie Hu,Chunfang Cai,Chelsea L. Pederson,Dawei Liu,Lei Jiang,Xunyun He,Shuyuan Shi,Adrian Immenhauser +7 more
TL;DR: In this article, a detailed analysis of the porosity evolution of the Dengying Formation is presented, and the significance of deep burial dissolution is critically discussed and constrained by: (i) corrosion of late diagenetic minerals, (ii) pores crosscutting (or forming around) stylolites and (iii) the occurrence of solid bitumen in the center of secondary pores.

Multistage dolomitization and formation of ultra-deep Lower Cambrian Longwangmiao Formation reservoir in central Sichuan Basin, China
TL;DR: In this paper, the origin of various types of dolomite for these carbonate reservoirs has not been well understood, and petrological studies, geochemical analyses including C, O and Sr isotopes, in-situ trace elements and rare earth elements, and fluid inclusions analyses are performed in order to uncover the Dolomitization mechanisms.
Journal ArticleDOI
Intra-horizon differentiation of the bacterial community and its co-occurrence network in a typical Plinthic horizon
TL;DR: It is shown that micro-zones even within a same plinthic horizon can provide different habitats and thus select for specific bacterial communities, which could improve the understanding of the differentiation of bacterial communities among microenvironments caused by both historical and contemporary processes.

Systematics of fluid inclusions in diagenetic minerals
TL;DR: The use of fluid inclusions as a means of understanding the physical and chemical history of fluids in sedimentary basins, but it also has revealed important limitations which have required that a new approach must be employed to effectively use fluid-inclusions.

Bacterial and thermochemical sulfate reduction in diagenetic settings — old and new insights
TL;DR: In this article, the authors show that sulfate reduction in diagenetic environments occurs in two mutually exclusive thermal regimes, i.e., low-temperature and hightemperature, respectively.
