Experimental study on reactions between alkaline basaltic melt and orthopyroxenes: constraints on the evolution of lithospheric mantle in the North China Craton
The experimental results of the reactions between an alkaline basaltic melt and mantle orthopyroxenes under high-temperature and high-pressure...

Widespread two-layered melt structure in the asthenosphere
Partial melts in the Earth’s convecting mantle influence its physical and chemical state, particularly the plasticity of the asthenosphere and the...

Titanium-rich basaltic melts on the Moon modulated by reactive flow processes
The origin of titanium-rich basaltic magmatism on the Moon remains enigmatic. Ilmenite-bearing cumulates in the lunar mantle are often credited as...

Feldspar Megacrysts as a Source of Information on Crustal Contamination of Basaltic Melt
Abstract—The paper discusses data on the elemental composition and 87 Sr/ 86 Sr, and δ 18 O isotopic ratios of feldspar megacrysts collected from lava...

A comparative study on pressure-induced structural transformations in a basaltic glass and melt from Ab initio molecular dynamics calculations
Glasses are often used as models for understanding the corresponding liquid melts because they are generally assumed to share similar short and...
-
Quenching of basaltic melts by volatile exsolution
Normally, volatiles in silicate melts are ephemeral components that escape as gases when the melt reaches fluid saturation. When fluid saturation...

Basaltic and Other Low-Viscosity Lavas
This chapter summarises the eruption processes, flow behaviour, and characteristics of low-viscosity basalt lavas. Basalts are primitive magmas...

Trace element partitioning in basaltic systems as a function of oxygen fugacity
Along with temperature, pressure and melt chemistry, magmatic oxygen fugacity ( f O 2 ) has an important influence on liquid and solid differentiation...

Experimental settling, floatation and compaction of plagioclase in basaltic melt and a revision of melt density
Centrifuge-assisted piston cylinder experiments were conducted on plagioclase in basaltic melt at 1140–1250 °C, 0.42–0.84 GPa and mostly 1000 g. One...

Magma recharge in persistently active basaltic–andesite systems and its geohazards implications: the case of Villarrica volcano, Chile
We report whole-rock chemistry, mineral chemistry, and volatile content from Villarrica volcano’s major recent paroxysms and background activity....

Mineral-melt vanadium oxybarometry for primitive arc magmas: effect of hydrous melt composition on fO2 estimates
If primitive arc magmas are primarily oxidized or if they acquire their oxidizing character during crustal evolution remains debated. Mineral-melt V...

The Physicochemical Conditions for the Formation of Recent Basalts of Lokon Volcano, Sulawesi Island in the Pacific Ocean: Melt Inclusion Data
We studied phenocrysts and melt inclusions in order to evaluate physical and chemical conditions of petrogenesis of the Sulawesi Island (southwestern...

Deciphering magmatic processes from plagioclase, clinopyroxene and amphibole chemistry and textures: A case study of a basaltic lava flow in the Basque-Cantabrian Basin (Northern Spain)
This paper addresses the study of a pillow lava interbedded with Late Albian-Early Cenomanian sediments that crops out in Armintza (Bizkaia, Northern...

Mineralogical and Geochemical Constraints on the Mantle Source Characteristics of Basaltic Lavas from the Central Mariana Trough
The composition of mantle-derived basalts reflects the nature of their mantle source regions, which constrain magma generation and composition. Here...

Modeling decompression paths in a basaltic andesite magma using the nucleation and growth of plagioclase microlites
Plagioclase microlites in a magma nucleate and grow in response to melt supersaturation (Δ ϕ plag ). The resultant frozen plagioclase crystal size...

Basaltic cognate enclaves from Dokdo Island as a window for intraplate mafic alkaline OIB magma dynamics in a back-arc basin
Volcanoes with ocean island basalt (OIB)-like characteristics occur in all settings. Their origin is particularly enigmatic when they occur in close...

Forsterite-Diopside-Anorthite: A Basaltic Analog
Our models for basalt have so far dealt only with plagioclase and pyroxene, the two dominant minerals in most basalts. We have ignored olivine and...

Origin of the Paleoproterozoic basaltic dikes from the central and eastern Dharwar Craton and sills and volcanics from the adjoining Cuddapah Basin, southern India
Reverse fractionation modeling considering energy-constrained assimilation-fractional crystallization is performed to estimate primary magma...

Petrogenesis of Miocene to Quaternary primitive basaltic magmas in the area of Lake Van (East Anatolia, Turkey): a case for relamination of mantle lithosphere after lithospheric delamination
We present the geochemical and Sr–Nd–Pb isotopic data and the petrological evolution of primitive basaltic lavas that erupted from the Miocene to...

Tephra dispersal and composition reveal the explosive onset of a large basaltic fissure eruption: Timanfaya, Lanzarote, 1730–1736 CE
Basaltic fissure eruptions are chiefly characterized by sizable emissions of lava flows and volcanic gases, posing significant hazards. However, such...
