Bottom morphology in the Song Hau distributary channel, Mekong River Delta, Vietnam

Continental Shelf Research, 2017
Abstract Field studies in the Song Hau distributary of the Mekong Delta in Vietnam conducted at high (Sept.-Oct 2014) and low (March 2015) Mekong River discharge are utilized to examine channel bottom morphology and links with sediment transport in the system. Multibeam bathymetric mapping surveys over the entire channel complex in the lower 80 km of

Bed‐scale quantitative discrimination of hyperpycnites from intrabasinal turbidites—Results from a channelised slope system in the Upper Carboniferous Westward Ho! Formation, United Kingdom

Sedimentology, Volume 73, Issue 5, Page 1750-1798, August 2026.
ABSTRACT Features considered indicative of hyperpycnites and intrabasinal turbidites overlap. Outcrop study presented here suggests that the Westward Ho! Formation forms an 800 m high deepwater‐slope system dominated by hyperpycnites. Taking this unit, and other successions where hyperpycnites have been described, as having been deposited solely from ...

Spatial Variations in Methane Content and Their Main Controlling Factors of the Deep‐Buried Coalbed in the Nalinhe–Hengshan Area, Ordos Basin

Energy Science &Engineering, Volume 14, Issue 7, Page 3422-3433, July 2026.
Ash yield is the primary geological factor controlling the spatial variations in the total gas content of the deep‐buried coalbed methane in the Nalinhe‐Hengshan area, Ordos Basin. However, porosity dominates the differential enrichment of the free gas content of the deep‐buried coalbed methane in the Nalinhe‐Hengshan area, Ordos Basin.

Present Estimations of Subsidence Induced by Sediment Isostasy and Glacial Isostatic Adjustment in the Ayeyarwady Delta (Myanmar)

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Estimating relative sea level rise, which measures changes in sea level compared to the land where people live, is crucial for the Ayeyarwady Delta, home to 15 million residents on this low‐lying delta. Like many large deltas, the Ayeyarwady Delta should experience subsidence from its own weight, worsening the effects of sea level rise ...

Implications of Flume Simulation for the Architectural Analysis of Shallow-Water Deltas: A Case Study from the S Oilfield, Offshore China

Journal of Marine Science and Engineering
The shallow-water delta-front reservoir in Member II of the Oligocene Dongying Formation (Ed2), located in an oilfield within the Bohai Bay Basin, is a large-scale composite sedimentary system dominated by subaqueous distributary channels and mouth bars.

Correlating High‐Resolution Terrestrial Organic Carbon Isotope Records Across the Cretaceous‐Paleogene Boundary

Paleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.
Abstract The Cretaceous–Paleogene boundary (∼66 million years ago) represents the most recent mass extinction event when an estimated 75% of all species became extinct, including all non‐avian dinosaurs. Here we focus on the stable carbon isotope (δ13C) analysis of coal and coaly sediments across the terrestrial K/Pg boundary from 10 sites, between 42 ...

Sedimentary characteristics and facies model of gravity flow deposits of Late Triassic Yanchang Formation in southwestern Ordos Basin, NW China

Petroleum Exploration and Development, 2015
Based on cores and logging data, and gravity flow theory, the sedimentary characteristics and facies model of gravity flow deposits in the Longdong area in southwestern Ordos Basin were analyzed. Five types of gravity flow deposits are recognized: slides,

Geological processes shaping freshwater biodiversity: a synthesis of global evidence

Biological Reviews, Volume 101, Issue 3, Page 1568-1581, June 2026.
ABSTRACT Recent genomic data highlight the key roles of geological processes in shaping the diversification and biogeography of freshwater lineages. Specifically, physical processes such as tectonic uplift, erosion, glaciation, lake formation, and sea‐level fluctuation contribute extensively to the evolution of biotic diversity within and among ...
