Enrichment Mechanism of the Organic‐Rich Shale in Ediacaran Doushantuo Formation in Western Sichuan Basin, South China

Geofluids, Volume 2025, Issue 1, 2025.
The Ediacaran Doushantuo Formation in South China has been increasingly recognized as a significant potential source rock for hydrocarbon reservoirs, particularly in relation to the overlying Dengying Formation. This study conducts a comprehensive geochemical analysis of the organic‐rich shale from the Ebian‐Xianfeng section within the Sichuan Basin ...

Height Propagation Law and Controlling Strategies of Acid Fractures in Carbonate Gas Reservoirs With Bottom Water Layer Under Different Stress Profiles

Geofluids, Volume 2025, Issue 1, 2025.
Acid fracturing is currently employed to develop the carbonate gas reservoir in the second section of the Dengying Formation at the Anyue Gas Field, Sichuan Basin. However, improper acid‐fracturing operational parameters pose a risk of fracture communication with the bottom water layer, leading to increased water production and a significant decline in

Laser ablation in situ U-Pb dating and its application to diagenesis-porosity evolution of carbonate reservoirs

Petroleum Exploration and Development, 2019
Through the development and calibration of a reference material which is 209.8 Ma old using a newly-developed Laser Ablation (LA) Multi-Collector Inductively Coupled Plasma Mass Spectrometry (MC-ICP-MS) technique, we successfully overcome the difficulty ...

Primary microfossiliferous chert in the Aptian Barra Velha Formation

Sedimentology, Volume 71, Issue 6, Page 1815-1842, October 2024.
ABSTRACT The Barra Velha Formation and other Aptian pre‐salt deposits record the history of the proto‐Atlantic basin and the rifting of Gondwana. Studies have sought to characterize the depositional environment of the basin with a focus on carbonate fabrics and magnesium silicate clays.

Sphalerite Records Cd Isotopic Signatures of the Parent Rocks in Hydrothermal Systems: A Case Study From the Nayongzhi Zn–Pb Deposit, Southwest China

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 5, May 2024.
Abstract Metal stable isotopes (e.g., Zn, Cd, and Cu) have been used to track metal sources in different types of hydrothermal systems. However, metal isotopic variations in sulphides could be triggered by various factors such as mineral precipitation and fluid mixing.

Morphological disparity and evolutionary patterns of Cambrian hyoliths

Papers in Palaeontology, Volume 10, Issue 2, March/April 2024.
Abstract Hyolitha represent one of the major constituents of the Cambrian Evolutionary Fauna, first appearing in the Terreneuvian and rapidly diversifying soon after. Recent work has both enriched the hyolith fossil record and expanded our understanding of their biology, but studies documenting the evolutionary trajectory of Cambrian hyoliths remain ...

Decline and fall of the Ediacarans: late‐Neoproterozoic extinctions and the rise of the modern biosphere

Biological Reviews, Volume 99, Issue 1, Page 110-130, February 2024.
ABSTRACT The end‐Neoproterozoic transition marked a gradual but permanent shift between distinct configurations of Earth's biosphere. This interval witnessed the demise of the enigmatic Ediacaran Biota, ushering in the structured trophic webs and disparate animal body plans of Phanerozoic ecosystems.

Retrogradation of carbonate platforms on a rifted margin: the late Ediacaran record of the northwestern Yangtze Craton (SW China)

Frontiers in Earth Science
The Late Ediacaran Dengying Formation, located in the Sichuan Basin of the northwestern Yangtze Craton, is of significant interest in oil and gas exploration due to its abundant pores and vugs within microbial mound-shoal complexes.
