From shape to source: sedimentary charcoal morphology as a proxy for tropical burned biomass composition

Journal of Quaternary Science, EarlyView.
ABSTRACT Sedimentary charcoal elongation is increasingly being used in paleoecology to distinguish herbaceous from woody fuel in past fires. However, the relationship between charcoal morphotypes and plant types has never been formally tested in tropical environments, despite its potential to improve understanding of fire regimes and deforestation, and

Modeling of hydrocarbon generation by Domanic source rock of the Timan‑Pechora basin using different kinetics of kerogen decomposition

Georesursy, 2017
Domanic Upper Devonian deposits of the Timan-Pechora petroleum province are the subject of growing scientific and practical interest from the time of its discovery (late 19th century).

Northern Hemisphere Glaciation during the Globally Warm Early Late Pliocene [PDF]

, 2013
The early Late Pliocene (3.6 to ~3.0 million years ago) is the last extended interval in Earth's history when atmospheric CO2 concentrations were comparable to today's and global climate was warmer.

From Ice to Isolation: A geochemical reconstruction of the palaeoenvironmental evolution of Gairloch, NW Scotland (UK), since the Last Glacial Maximum

Journal of Quaternary Science, EarlyView.
ABSTRACT Complex relative sea‐level (RSL) changes are associated with the deglaciation of the British and Irish Ice Sheet (BIIS). Sediment archives from Loch Bad na h‐Achlaise, an isolation basin in NW Scotland, UK, span Late Glacial to Holocene time and record sea‐level change and ice proximity via a geochemical and biostratigraphic multiproxy ...

Mineralogical modelling and petrophysical parameters in Permian gas shales from the Roseneath and Murteree formations, Cooper Basin, Australia

Petroleum Exploration and Development, 2016
To estimate the resources of Permian Roseneath and Murteree gas shales in the Cooper Basin, Australia, geochemical analysis, log interpretation and core analysis techniques were combined to conduct mineralogical modelling and define petrophysical ...

Influence of chemical reaction kinetics on electrokinetic remediation modelling results [PDF]

, 2017
A numerical model describing transport of multiple species and chemical reactions during electrokinetic treatment is presented. The transport mechanisms included in the model were electromigration and electroosmosis.

Reconstructing post‐crisis recovery in the hinterlands of Constantinople: A high‐resolution first‐millennium CE pollen record from Lake Yeniçağa (NW Türkiye)

Journal of Quaternary Science, EarlyView.
ABSTRACT Facing a novel plague pandemic, military invasions, and political–economic transformations, societies of the eastern Roman (Byzantine) empire had to adapt to a variety of pressures and new ways of exploiting their natural environments during the mid‐1st millennium CE.

Methanogenesis in oxygenated soils is a substantial fraction of wetland methane emissions

Nature Communications, 2017
Methane production is traditionally not found in oxygenated soils, a paradigm incorporated in global greenhouse gas modelling efforts. Here the authors show geochemical and biological evidence of active methanogenesis in bulk-oxic wetland soils ...

Ex-situ mineral carbonation: resources, process and environmental assessment (Carmex project) [PDF]

, 2013
This article presents the main results of the Carmex project (2009-2012), whose purpose was to review the feasibility of ex-situ mineral carbonation in terms of resource availability, performance of the aqueous mineral carbonation process and life cycle ...
