Petrology, geochemistry, and crystal size distribution of the basaltic andesite–dacite association at Mt. Sumbing, Central Java, Indonesia: Insights to magma reservoir dynamics and petrogenesis
Ten rock samples consisting of one pyroclastic density current (PDC1) deposit, seven lava flows (LF1–7), and two summit lava domes (LD1, 2) were...

Cooling history and emplacement dynamics within rubbly lava flows, southern Deccan Traps: insights from textural variations and crystal size distributions
We analyse two representative rubbly pāhoehoe lavas (F3 and F5) from drill cores at Tural-Rajwadi, southwest of Koyna, in the southern Deccan Traps....

Magma mingling during the 1959 eruption of Kīlauea Iki, Hawaiʻi
Magma mingling and mixing are common processes at basaltic volcanoes and play a fundamental role in magma petrogenesis and eruption dynamics....

Ecological distribution and population structure of Litsea glaucescens (Lauraceae) in the ravines of Sierra Fría and Sierra Laurel, Central Mexico
Litsea glaucescens Kunth (Mexican bay leaf, laurel) has a wide distribution in Mexico, growing at both riparian and rupicolous environments in the...

Distribution, intensity, and timing of palagonitization in glaciovolcanic deposits, Cracked Mountain volcano, Canada
The Cracked Mountain edifice is a basaltic subglacial volcano (i.e. tuya) situated in southwest British Columbia, Canada. The edifice is dominated by...

Total grain size distribution of components of fallout deposits and implications for magma fragmentation mechanisms: examples from Campi Flegrei caldera (Italy)
In this paper, we present results of the reconstruction of the total grain size distribution (TGSD) of the material erupted during explosive volcanic...

Vesicle shrinkage in hydrous phonolitic melt during cooling
The ascent of hydrous magma prior to volcanic eruptions is largely driven by the formation of H 2 O vesicles and their subsequent growth upon further...

Timescales and mechanisms of paroxysm initiation at Stromboli volcano, Aeolian Islands, Italy
New textural and petrological data are presented on products from five paroxysms at Stromboli (Aeolian Islands, Italy) including the two from 2019...

Sink or float: microtextural controls on the fate of pumice deposition during the 2012 submarine Havre eruption
Silicic submarine volcanic eruptions can produce large volumes of pumices that may rise buoyantly to the ocean surface and/or sink to the seafloor....

Shearing characteristics and shearing resistance mechanism of volcanic soil with high vesicularity
Basaltic scoria soil with high vesicles is widely distributed in eastern Jilin, China. The vesicle content varies considerably in different grain...

Petrophysical Texture Heterogeneity of Vesicles in Andesite Reservoir on Micro-Scales
It is of great significance to study the spatial distribution patterns and petrophysical complexity of volcanic vesicles which determine whether the...

Mafic explosive volcanism at Llaima Volcano: 3D x-ray microtomography reconstruction of pyroclasts to constrain shallow conduit processes
Mafic volcanic activity is dominated by effusive to mildly explosive eruptions. Plinian and ignimbrite-forming mafic eruptions, while rare, are also...

Sulfide minerals and chalcophile elements in The Pleiades Volcanic Field, Antarctica: implications for the distribution of chalcophile metals in continental intraplate alkaline magma systems
Fractionation of sulfides during ascent of mantle-derived magmas distributes sulfur and chalcophile elements into the Earth’s lithosphere. It has...

Fragmentation Processes in Magmas and Volcanic Rocks
In this chapter, we consider the many processes by which magma and volcanic rock can be fragmented. This comprehensive review describes the...

Morphology, Textures and Thicknesses of Rubbly Pahoehoe Lavas from the ∼117 Ma Sylhet Traps, India
The Sylhet Traps and the larger outcrops of the Rajmahal Traps in India constitute an important remnant of a large Continental Flood Basalt (CFB)...

Characterising the wind-advected medial fall deposit from fissure 8 fountaining during the 2018 lower East Rift Zone eruption, Kīlauea
The 2018 eruption on the lower East Rift Zone, Hawaii, involved the opening of 24 fissures before the eruption focussed on a single point source,...

Total grain size distribution of an intense Hawaiian fountaining event: case study of the 1959 Kīlauea Iki eruption
The 1959 eruption of Kīlauea Iki on the Island of Hawai’i is a principal example of powerful Hawaiian fountaining. Over 36 days (including repose...

Molecular identification, expression pattern, and in-vitro bioactivity analysis of insulin-like growth factor 2 in olive flounder Paralichthys olivaceus
Insulin-like growth factors (IGFs) are key regulators of development and growth. Here, we characterized the igf2 gene from olive flounder ( Paralichthy...

Estimates of the Fecundity of the Atlantic chub Mackerel Scomber colias (Gmelin, 1789) in the Northeast Atlantic and Mediterranean Moroccan Coasts
Fish fecundity is a key life history characteristic, and can be used in stock assessment and management. In this study, we estimated the batch...

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...
