Meteoritics &Planetary Science, EarlyView.Abstract Meteorite collection inventories show that many related meteorite groups have very different numerical abundances (e.g., lunar versus Martian meteorites; Eagle Station pallasites versus main‐group pallasites; eucrites versus diogenites; ungrouped Antarctic irons versus ungrouped non‐Antarctic irons; carbonaceous chondrite‐related (CC) iron ...

Indonesian Journal on Geoscience, 2014 DOI: 10.17014/ijog.v6i4.129The effusive eruption of Kelud Volcano in 2007 was different from the previous ones, which in general were more explosive. Among others, density and viscosity are factors that determine the type of eruption.

A noise‐based framework for randomly generating soil particle with realistic geometry
Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 13, Page 1829-1846, 19 May 2025.Abstract Particle morphology influences the mechanical behavior of granular soils. Generating particles with realistic shapes for discrete element method simulations is gaining popularity. However, it is still challenging to efficiently generate very angular particles with less computational cost.

Geochemistry, Geophysics, Geosystems, 2020 Two end‐member conceptual models are used to describe deformation of the Earth's crust induced by magma intrusion. “Mode I” fracturing assumes tensile or opening‐mode, elastic deformation, while “Mode II” fracturing assumes plastic shear‐mode deformation

Rapid heterogeneous assembly of multiple magma reservoirs prior to Yellowstone supereruptions
Scientific Reports, 2015 Large-volume caldera-forming eruptions of silicic magmas are an important feature of continental volcanism. The timescales and mechanisms of assembly of the magma reservoirs that feed such eruptions as well as the durations and physical conditions of ...

Hydrous Asthenosphere Underneath the Northern Pannonian Basin
Terra Nova, Volume 37, Issue 3, Page 164-174, June 2025.ABSTRACT This study reveals the structural hydroxyl content in clinopyroxenes of three cumulate xenoliths from the Nógrád‐Gömör/Novohrad‐Gemer Volcanic Field (northern Pannonian Basin), with values ranging from 275 to 384 ppm. Based on these data, the water content of the equilibrium parental alkali basaltic melt was estimated to be between 1.5 and 2.1

The Chamrousse Ophiolite (Western Alps, France): Relict of a Devono‐Carboniferous Ocean
Terra Nova, EarlyView.ABSTRACT The Chamrousse ophiolite (Western Alps, France) is one of the best‐preserved Variscan relicts of Cambro‐Ordovician oceanisation within the northern Gondwana margin. This study presents new in situ U–Pb isotope analyses on zircon grains from that ophiolite, revealing that the oceanic stage in Chamrousse has occurred 150 Ma later than estimated.

The chlorine isotope fingerprint of the lunar magma ocean
Science Advances, 2015 The unusually heavy Cl of the Moon is related not to degassing of dry magmas but rather to the loss of Cl from the lunar magma ocean. The Moon contains chlorine that is isotopically unlike that of any other body yet studied in the Solar System, an ...

Terra Nova, EarlyView.ABSTRACT Laser ablation U–Pb single zircon geochronology was applied to four peraluminous granite and granodiorite samples from the Bassiès pluton in the Central Pyrenees (France) yielding a wide range of concordant ages from early Carboniferous (Tournaisian, 351 Ma) to early Permian (Artinskian, 285 Ma).

Terra Nova, EarlyView.ABSTRACT The Hokuroku district of NE Japan hosts the type locality for Kuroko volcanic‐hosted massive sulphide (VHMS) deposits, which are the product of seafloor hydrothermal venting in a continental rift during the opening of the Sea of Japan in the Miocene.
