The Salittu Formation in southwestern Finland, part I: Structure, age and stratigraphy [PDF]

Bulletin of the Geological Society of Finland, 2016
Because of the relatively low metamorphic grade, low strain and well-preserved early structures in volcanic and volcaniclastic rocks, the Orijärvi triangle (in the center of the larger Orijärvi area) is one of the few locations in the Svecofennian orogen

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 ...

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).

Thallium isotopes reveal protracted anoxia during the Toarcian (Early Jurassic) associated with volcanism, carbon burial, and mass extinction

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance Declining oxygen contents in today’s oceans highlight the need to better understand ancient, natural marine deoxygenation and associated extinctions.

Magmatism and volcanism on Io

, 2021
Global volcanism has implications for planetary evolution far beyond the surface features that we observe. Magmatic and volcanic processes control the structural, thermal and compositional evolutions of the bodies where they operates.

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.
