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.

Untangling sedimentation processes in a deep fjord lake in Labrador: A high‐resolution archive of past environment dynamics at Grand Lake

The Depositional Record, EarlyView.
Sedimentological and geochemical characteristics are used to reconstruct sedimentation dynamics and erosional processes. Several rapidly deposited layers are characterised over changing depositional environments during the Late Holocene, from a phase when the lake was connected to the sea to a more stable state conducive to varve formation.

Petrology, Palynology, and Geochemistry of Gray Hawk Coal (Early Pennsylvanian, Langsettian) in Eastern Kentucky, USA

, 2015
This study presents recently collected data examining the organic petrology, palynology, mineralogy and geochemistry of the Gray Hawk coal bed. From the Early Pennsylvanian, Langsettian substage, Gray Hawk coal has been mined near the western edge of the

Anomalously cool clumped isotope temperatures in tropical lagoon carbonates

The Depositional Record, EarlyView.
Carbonate clumped isotopes were used to reconstruct paleoclimate from lagoon sediments in the central tropical Pacific. Results were anomalously cool compared to modern measurements and other paleoclimate records. This study highlights the important of understanding carbonate facies and depositional environments in interpreting clumped isotope results.

Magma storage conditions beneath Krakatau, Indonesia: insight from geochemistry and rock magnetism studies

Frontiers in Earth Science, 2023
Understanding the evolution of magma storage conditions on volcanoes which have had more than one caldera-forming eruption (CFE) is important to know about past and present conditions, as a key to forecast future potential hazards.

Stratigraphy of diagenesis: Limestone–dolomite cycles in a mid‐ramp setting, Miocene Arcadia Formation, South Florida, USA

The Depositional Record, EarlyView.
The data and interpretations of this study are used to test the proposal by Goldhammer et al. that a ‘stratigraphy of early diagenesis’ is operational in carbonate depositional systems. What this means is that distinct mineralogical and geochemical changes to rock and sediment occur associated with external controls, such as the rise and fall of sea ...

Diagenetic processes controlled by volcanic detritus of the Lower‐Middle Permian Shanxi and Shihezi sandstone formations, North Ordos Basin, China

The Depositional Record, EarlyView.
Comparisons of Lower‐Middle Permian Shanxi and Lower Shihezi formations from the North Ordos Basin reveal that different types and percentages of volcanic detritus induced by active magmatic cycles can significantly change diagenetic evolution and favourable reservoirs.

A continuous 500‐year sediment record of inundation by local and distant tsunamis in South‐Central Chile (40.1°S)

The Depositional Record, EarlyView.
Tsunami events over the past 500 years inundated Laguna Gemela West (Chile), leading to distinct sandy deposits in the lake record. This provides a complete perspective on tsunami inundation, including giant tsunamis, small local tsunamis and tsunamis that originated >100 km away from the site.
