Deep Learning Investigation of Mercury’s Explosive Volcanism

Remote Sensing, 2023
The remnants of explosive volcanism on Mercury have been observed in the form of vents and pyroclastic deposits, termed faculae, using data from the Mercury Atmospheric and Surface Composition Spectrometer (MASCS) onboard the Mercury surface, space ...

THE ITALIAN QUATERNARY VOLCANISM

Alpine and Mediterranean Quaternary, 2023
Volcanic products undoubtedly represent an im-portant part of the Quaternary deposits in Italy. For this reason, we have decided to take the opportunity offered by the INQUA conference to be held in Rome in 2023 to present a review of the state of the art and knowledge of the Italian Quaternary volcanism.

Evolution of the volcanic mechanism in the central part of the Urumieh-Dokhtar magmatic arc

Journal of Economic Geology, 2021
Introduction Cenozoic volcanic activities in the Urumieh-Dokhtar Magmatic Arc (UDMA) have occurred in three main pulses of Eocene, upper Oligocene-Pliocene, and Pio-Quaternary (Dilek et al., 2010, Sayari, 2015).

Volcanism of the South Aegean Volcanic Arc [PDF]

Elements, 2019
Volcanism along the South Aegean volcanic arc began about 4.7 Ma and has lasted until the present day, with eruptions at Methana, Milos, Santorini, Kolumbo and Nisyros volcanoes in historical times. These volcanoes can be grouped into five volcanic fields: three western fields of small, mostly monogenetic edifices, and two central/eastern fields with ...

Modeling Wavelength Dependent Mid‐Infrared (5.5–25 μm) Optical Constants of Silicate Glasses: A Genetic Algorithm Approach

Earth and Space Science, 2023
Wavelength‐dependent mid‐infrared (400–1,800 cm−1; 5.56–25 μm) optical constants (real and imaginary indices of refraction; n and k) are determined using reflectance spectra at a spectral sampling of 4 cm−1 for several silicate glasses of varying SiO2 wt%

Intensive Wildfire Associated With Volcanism Promoted the Vegetation Changeover in Southwest China During the Permian−Triassic Transition

Frontiers in Earth Science, 2021
Palaeo-wildfire, which had an important impact on the end Permian terrestrial ecosystems, became more intense in the latest Permian globally, evidenced by extensive occurrence of fossil charcoals.

Komatiitic explosive volcanism and its tectonic setting in Finland, the Fennoscandian (Baltic) Shield [PDF]

Bulletin of the Geological Society of Finland, 1990
The variously explosive komatiitic volcanism in Finland was virtually confined to the Archaean continental segment, where it occurred in the Lapland and Kuhmo‒ Suomussalmi greenstone belts between 3.0 Ga and 2.5 Ga, in the continental borderland at 1.97 ...
