This study calculated the texture coefficient (TC) values of 20 different rock textures with magmatic, metamorphic, and sedimentary origins, which underwent image segmentation using a novel approach. ABSTRACT The texture coefficient (TC) is a critical parameter used to analyze the microstructural characteristics of rocks and predict their mechanical ...

Large igneous provinces and mass extinctions: an update [PDF]
The temporal link between mass extinctions and large igneous provinces is well known. Here, we examine this link by focusing on the potential climatic effects of large igneous province eruptions during several extinction crises that show the best ...

Challenges in dating blanket peat and implications for understanding its initiation in Ireland
ABSTRACT Blanket peat is widespread in maritime extra‐tropical environments. Prehistoric land‐use activity was traditionally invoked as the stimulus of blanket peat initiation in the British Isles, but recently, climate has been viewed as the driver of peat formation.

Lunar basalt chronology, mantle differentiation and implications for determining the age of the Moon [PDF]
Despite more than 40 years of studying Apollo samples, the age and early evolution of the Moon remain contentious. Following the formation of the Moon in the aftermath of a giant impact, the resulting Lunar Magma Ocean (LMO) is predicted to have ...

Recent advancements in spectral and spatial resolutions for Raman spectroscopy allow the analysis of fluid and melt inclusions. To explore the applicability of 3D Raman mapping, we conducted 3D Raman mapping on inclusions hosted by orthopyroxene in modally metasomatized mantle xenoliths from the Styrian Basin (W‐Carpathian Pannonian Region).

Abstract Islands in the tropical Pacific supply elevated nutrients to nearshore waters that enhance phytoplankton biomass and create hotspots of productivity in otherwise nutrient‐poor oceans. Despite the importance of these hotspots in supporting nearshore food webs, the spatial and temporal variability of phytoplankton enhancement and changes in the ...
