Geobiology of bituminous carbonates from the Ediacaran Shibantan Member (Dengying Formation, South China) [PDF]

, 2022
The Shibantan Member is one of only two known carbonate settings characterised by a 'typical' Ediacaran fossil association including Ediacara-type fossils. Aim of this project was a comprehensive geobiological characterisation of the Shibantan Member, addressing both sedimentological and biogeochemical issues in order to gain a better understanding of ...

Re-Os dating and oil-source correlation of the pyrobitumen in the Member 4, Dengying Formation of the Kangjiadong paleo-reservoir, northern margin of the Sichuan Basin

, 2022
There are pervasive pore-filling bitumen found in the dolomite reservoir of the Member 4 , Sinian Dengying Formation. However, the high maturity of the source rocks and bitumen and the complex geological tectonic activities make it difficult to restore ...

CHARACTERISTICS AND ORIGIN OF THE DOLOSTONES OF THE EDIACARAN DENGYING FORMATION IN THE EASTERN SICHUAN BASIN, SOUTH CHINA

Carpathian Journal of Earth and Environmental Sciences, 2022
The Ediacaran Dengying Formation dolostones were the crucial carrier of the co-evolution between the biota and environment before the Cambrian Explosion and the solid mineral and petroleum resources. Based on the petrological and mineralogical analyses, the Dengying Formation at the Liaojiacao Section consists of micritic, fine-crystalline and medium ...

Study on the Fracture Formation Mechanisms in Reservoir Rocks of the Second Member of the Dengying Formation in the Sichuan Basin

Journal of Physics: Conference Series
Abstract The second member of the Dengying formation (DYF M2) in the Sichuan Basin holds substantial potential for exploration and development, with fractures serving as a pivotal factor for the efficient extraction of natural gas resources within this formation.

Uranium Isotope Evidence for Persistent Global Ocean Anoxia Across the Ediacaran–Cambrian Transition in Siberia

Geobiology, Volume 24, Issue 5, September/October 2026.
ABSTRACT The enigmatic Ediacara biota represents Earth's earliest example of macroscopic, complex life, yet the driving forces promoting their mid‐Ediacaran evolution and subsequent extinction across the Ediacaran–Cambrian boundary remain speculative. If these were true animals requiring oxygen for aerobic respiration, their rise has often been linked ...

Evolution of diagenetic fluids in the deeply buried, upper Ediacaran Dengying Formation, Central Sichuan Basin, China

, 2022
Deeply buried Precambrian carbonate reservoirs host economic petroleum reserves. The upper Ediacaran Dengying Formation (maximum burial depth >8 km) is predominantly composed of dolostone with porosity ranging from 2 to 4%, and minor limestone with a ...

Microbially Mediated Intracellular Barite Mineralization: Evidence From an Early Ediacaran Microfossil in the Doushantuo Formation of South China

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Barite serves as a key proxy for reconstructing paleo‐oceanic productivity and chemistry in modern and ancient marine sediments. Although contemporary barite precipitation involves biological mediation, the mechanisms responsible for ancient barite formation remain unclear.

Estimation of the Transverse Wave Velocity in Siliceous Carbonate Reservoirs of the Dengying Formation in the Gaoshiti–Moxi Area, Sichuan Basin, China

, 2023
Siliceous minerals of the Dengying Formation in the Gaoshiti–Moxi area in the central Sichuan Basin exhibit four types of quartz crystals (cryptocrystalline quartz, chalcedony, microcrystalline quartz, and megacrystalline quartz) and three ...
