Fifty years of research on the Joulters ooid sandbody—Impact on carbonate sedimentology and diagenesis and lessons learned from an invaluable analogue

The Depositional Record, EarlyView.
The Joulters ooid sandbody of northern Great Bahama Bank is a vast expanse of muddy ooid sands partly rimmed by clean ooid sands and formed into a relatively thick layer of significant extent. Knowledge of the development of depositional and diagenetic patterns in the Joulters example has forwarded our general understanding of carbonate sedimentology ...

A man with leonine facies [PDF]

BMJ Case Reports, 2012
A 42-year-old man presented with gradually progressive thickening of his scalp, face and extremities. He also complained of hyperhidrosis of palms and sole. On examination, he had coarse ‘leonine like’ facies, with thickened folded skin of face, eyelids and scalp with mechanical partial ptosis (figure 1).

Dynamic fluvial systems and gravel progradation in the Himalayan foreland [PDF]

, 2000
Although the large-scale stratigraphy of many terrestrial foreland basins is punctuated by major episodes of gravel progradation, the relationships of such facies to hinterland tectonism and climate change are often unclear. Structural reentrants provide

Petrophysical Characterization of Fractured Limestone from Beauce Aquifer Vadose Zone (O-ZNS Observatory, France) [PDF]

85th EAGE Annual Conference & Exhibition - Workshop Programme, Jun 2024, Oslo, Norway. pp.1-5
In recent years, water needs increased, driven by climate change and world population growth. In this context, we study groundwater flow in the vadose zone of Beauce aquifer (O-ZNS site, France). This lacustrine limestone vadose zone is characterized by multi-scale heterogeneities. They are defined by strongly various pore structures.

Water pathways and ancient lakes: Flowing towards new models to unravel the past

The Depositional Record, EarlyView.
Abstract Significant progress has been made in understanding lake basin evolution through climatic and tectonic changes using sedimentology, sequence stratigraphy, geochemistry, hydrology and watershed characteristics to interpret three main lake basin types: overfilled, balanced‐fill and underfilled, including fluvio‐lacustrine systems.

An investigation of subfacies and representative microfacies of the Cretaceous Chishan Group in the Wubao fault zone of Gaoyou sag, Subei basin, China [PDF]

Journal of Petroleum Science and Technology, 2015
This study aims to identify favorable oil–gas reservoir facies in the Chishan group of the Wubao fault zone (Gaoyou sag, Subei basin, China) using the methods of outcrops and cores observation, granularity analysis, scanning electron microscope, log data,

Contributions of arid climate and hydrothermal fluid flow on sedimentation in saline‐alkaline lakes: Insight from the Ibar intramontane basin (Southern Serbia)

The Depositional Record, EarlyView.
The article demonstrates that brine was central for the supply of Ca and B to the studied saline lake. The ion transport occurred probably by thermal springs, while contributions from surface waters cannot be excluded. However, the saturation and syndepositional precipitation of Ca borates were initiated by an arid climate through evaporation, while ...

Biomineralization of primary carbonate cements: a new biosignature in the fossil record from the Anisian of Southern Italy

Lethaia, EarlyView., 2021
Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

Interpreting complex fluvial channel and barform architecture: Carboniferous Central Pennine Province, northern England. [PDF]

, 2018
The Bashkirian Lower Brimham Grit of North Yorkshire, England, is a fluvio-deltaic sandstone succession that crops out as a series of tors and pinnacles, the three-dimensional arrangement of which allows high-resolution architectural analysis of ...
