TLDR
Small-scale volcanic systems are commonly monogenetic in the sense that they are represented at the Earth's surface by fields of small volcanoes, each the product of a temporally restricted eruption of a compositionally distinct batch of magma, and this is in contrast to relatively large edifices built by multiple eruptions over longer periods of time involving magmas with diverse origins.Abstract:
Abstract Small-scale volcanic systems are the most widespread type of volcanism on Earth and occur in all of the main tectonic settings. Most commonly, these systems erupt basaltic magmas within a wide compositional range from strongly silica undersaturated to saturated and oversaturated; less commonly, the spectrum includes more siliceous compositions. Small-scale volcanic systems are commonly monogenetic in the sense that they are represented at the Earth's surface by fields of small volcanoes, each the product of a temporally restricted eruption of a compositionally distinct batch of magma, and this is in contrast to polygenetic systems characterized by relatively large edifices built by multiple eruptions over longer periods of time involving magmas with diverse origins. Eruption styles of small-scale volcanoes range from pyroclastic to effusive, and are strongly controlled by the relative influence of the characteristics of the magmatic system and the surface environment.read more

The intraplate Changbaishan volcanic field (China/North Korea): A review on eruptive history, magma genesis, geodynamic significance, recent dynamics and potential hazards
Maoliang Zhang,Zhengfu Guo,Jiaqi Liu,Guoming Liu,Lihong Zhang,Ming Lei,Wenbin Zhao,Lin Ma,Vincenzo Sepe,Guido Ventura +9 more
TL;DR: In this article, the authors present a geodynamic model of the Changbaishan volcanic field (CHVF) in the interior of the eastern Eurasian continent, which can be used to constrain the magma origin and geodynamic mechanism governing continental intraplate volcanism.

Review of Explosive Hydrovolcanism
Károly Németh,Szabolcs Kósik +1 more
TL;DR: A revised and reviewed classification of phreatomagmatism is proposed in this article, based on the geology in which the magma-water interaction takes place and the explosivity plus mode of energy transfer required to generate kinetic energy to produce pyroclasts.

TL;DR: In this paper, a new evaluation is made of parental magma compositions that would crystallize olivines with the maximum forsterite contents observed in lava flows, consistent with the plume model.

Volcanological perspectives on Long Valley, Mammoth Mountain, and Mono Craters: several contiguous but discrete systems
TL;DR: In this paper, the authors examined the volcanic history of the Long Valley region within a framework of six successive (spatially discrete) foci of silicic magmatism, each driven by locally concentrated basaltic intrusion of the deep crust in response to extensional unloading and decompression melting of the upper mantle.

Alkalic magmas generated by partial melting of garnet pyroxenite
TL;DR: In this paper, high-pressure partial-melting experiments on a garnet pyroxenite (MIX1G) at 2.0 and 2.5 GPa produce strongly ne-normative and silica-poor partial melts.
