The Silurian mesophotic coral ecosystems: 430 million years of photosymbiosis

Coral reefs, 2018
The Silurian Period witnessed one of the most profound intervals of reef development in the history of the Earth, formed in large part by tabulate and rugose corals and stromatoporoid assemblages.

Reservoir characterization and exploration potential of shale reservoir near denudation area: A case study of Ordovician–Silurian marine shale, China

Open Geosciences
The distribution of denudation areas has brought huge risks to the exploration and development of deep buried shale gas resources. The reservoir characterization and exploration potential near denudation areas is of great significance to the evaluation ...

Some new palynomorphs from the Silurian of the Quetame Massif, Cordillera Oriental, Colombia, South America

Boletín Geológico, 1994
During a palynological investigation of Paleozoic series in the Colombian Cordillera Oriental Silurian-indicating fossils were found in Colombia. In this paper we describe four palynomorphs which were significant for the Silurian of the Quetame Massif.

Cruziana traces from the Late Silurian (Pridoli) carbonate shelf of Saaremaa, Estonia [PDF]

Estonian Journal of Earth Sciences, 2014
Late Pridoli Cruziana traces have recently been found in carbonate shelf sediments of the Ohesaare Formation on Saaremaa Island, Estonia. Cruziana isp. is interpreted here as a locomotory trace (repichnia) of an arthropod, possibly a trilobite.

A Cenozoic-style scenario for the end-Ordovician glaciation [PDF]

, 2014
The end-Ordovician was an enigmatic interval in the Phanerozoic, known for massive glaciation potentially at elevated CO2 levels, biogeochemical cycle disruptions recorded as large isotope anomalies and a devastating extinction event.

Cryptic Paleomagnetic Complexity in the Ediacaran Egersund Dikes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract The Ediacaran Period (∼635–539 Ma) represents a critical interval in Earth's evolution, yet its paleomagnetic record remains complex and contentious. One of the few Ediacaran paleomagnetic results from Baltica considered robust is a pole from the ca.

Quantitative characterization of micropore structure for organic-rich Lower Silurian shale in the Upper Yangtze Platform, South China: Implications for shale gas adsorption capacity

, 2017
The pores in shales are mainly of nanometer-scale, and their pore size distribution is very important for shale gas storage and adsorption capacity, especially micropores having widths less than 2 nm, which contribute to the main occurrence space for gas

Optimization of Parsimonious and Synchronized Discharge and Dissolved Organic Carbon Models Across Catchment Scales

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract The production, transport, loss, and export of dissolved organic carbon (DOC) are closely connected with hydrometeorological drivers. While terrestrial production depends on biogeochemical variables like soil moisture, air temperature, and the contact area between water and organic matter sources, export is determined by water availability and
