Impact of wind direction variability on hazard assessment in Martinique (Lesser Antilles): The example of the 13.5 ka cal BP Bellefontaine Plinian eruption of Mount Pelée volcano
Audrey Michaud-Dubuy,Guillaume Carazzo,Stephen Tait,Guillaume Le Hir,Frédéric Fluteau,Edouard Kaminski +5 more
TL;DR: In this paper, the authors present a detailed reconstruction and reinterpretation of a poorly-understood eruption of Mount Pelee volcano (Martinique), and use it to demonstrate that exclusive use of the average trade wind profile can lead to a misrepresentation of the volcanic risk.

The complex response of continental silicate rock weathering to the colonization of the continents by vascular plants in the Devonian
Pierre Maffre,Yves Goddéris,Alexandre Pohl,Yannick Donnadieu,Sebastien Carpentier,Guillaume Le Hir +5 more
TL;DR: In this paper , a spatially-resolved erosion model is coupled to the GEOCLIM model to simulate the response of the global carbon and alkalinity cycles, and of climate, to the colonization phase of the Devonian.

TL;DR: In this article, environmental and biological consequences from the Chicxulub impact and emplacement of the Deccan continental flood basalts were explored using a climate-carbon-biodiversity coupled model called the ECO-GEOCLIM model.

Harsh or balmy weathering conditions onto the first continent surface
TL;DR: In this article, the question of weathering intensity on the first continent surface, so-called "Columbia", was addressed using the combination of a thermochemical and climatic model, based on the dissolution of a mix of silicates representative of the fresh rocks and the precipitation of secondary phases.

TL;DR: The International Commission on Stratigraphy is proposing to add an extra eon, the Hadean, covering the first 600 million years of the history of our planet as mentioned in this paper. But this eon is described as having an informal status since no pre-Archean rock has been observed today.
