The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Global Rates of Volcanism and Volcanic Episodes
, 2015 In this chapter we explore global volcanism production rates and ask whether global volcanism is constant or episodic in nature. Three categories of terrestrial volcanism are considered: (l) ocean ridge volcanism, (2) arc volcanism above subduction zones,

Tertiary-Quaternary intra-plate magmatism in Europe and its relationship to mantle dynamics [PDF]
, 2006 Anorogenic intra-plate magmatism was widespread in Europe from early Tertiary to Recent times, extending west to east from Spain to Bulgaria, and south to north from Sicily to northern Germany. Magmatism is spatially and temporally associated with Alpine-

Tectonic significance of changes in post-subduction Pliocene-Quaternary magmatism in the south east part of the Carpathian-Pannonian Region [PDF]
, 2010 The south-eastern part of the Carpathian–Pannonian region records the cessation of convergence between the European platform/Moesia and the Tisza–Dacia microplate.

Observing eruptions of gas-rich compressible magmas from space
Nature Communications, 2016 Satellite observations are an important tool in volcano monitoring, but observations such as ground deformation and gas emissions are treated independently. Here, the authors present a model coupling them through their link to magma volatile contents and

Supracrustal rocks in the Kuovila area, Southern Finland: Structural evolution, geochemical characteristics and the age of volcanism [PDF]
Bulletin of the Geological Society of Finland, 2005 The supracrustal rocks of the Kuovila area in the Palaeoproterozoic Svecofennian Uusimaa Belt, southern Finland, consist mainly of volcaniclastic rocks associated with banded iron formations (BIFs) and marbles.

40Ar/39Ar dating of Quaternary lavas in northwest Iran: constraints on the landscape evolution and incision rates of the Turkish-Iranian plateau [PDF]
, 2011 We report five new <sup>40</sup>Ar/<sup>39</sup>Ar ages for basaltic lavas in the Maku region of northwest Iran, between ca. 1.87 and 0.40 Ma, which help constrain the tectonic and landscape evolution of this part of the Turkish ...

A subduction and mantle plume origin for Samoan volcanism
Scientific Reports, 2018 The origin of Samoan volcanism in the southwest Pacific remains enigmatic. Whether mantle melting is solely caused by a mantle plume is questionable because some volcanism, here referred to as non-hotspot volcanism, defies the plume model and its linear ...

Specific changes of the Kolka Glacier (the North Caucasus) from 2002 to 2016
Лëд и снег, 2017 The process of filling the bed with ice with steep lateral tributaries, which lost support, began almost immediately after the catastrophe on the Kolka Glacier in 2002. Currently, three streams of ice have closed in the rear zone of the circus, forming a

Revealing 60 years of Earthquake Swarms in the Southern Red Sea, Afar and the Gulf of Aden
Frontiers in Earth Science, 2021 Earthquake swarms occur sporadically at divergent plate boundaries but their recurrence over multiple decades and relation to magmatic spreading activity remain poorly understood. Here we study more than 100 earthquake swarms over a 60-year period in the
