Geologic investigations of outer planets satellites [PDF]

open access: yes
Four tests are examined: (1) investigation of volcanism on Io; Interim results of thermal and structural modeling of volcanism on Io are presented, (2) a study of the ancient heavily cratered regions on Ganymede, (3) a geologic comparison of the ...

Heat flow from the Earth interior as indicator of deep processes

open access: yesGeoresursy, 2018
The energy aspects of the problem of intraterrestrial heat transfer in various forms are discussed. Endogenous causes of conductive heat flow dispersion − radiogenic heat generation, tectonic movements and magmatism (volcanism), including its latent and ...

Stress Controls of Monogenetic Volcanism: A Review

open access: yesFrontiers in Earth Science, 2016
The factors controlling the preparation of volcanic eruptions in monogenetic fields are still poorly understood. The fact that in monogenetic volcanism each eruption has a different vent suggests that volcanic susceptibility has a high degree of ...

East African topography and volcanism explained by a single, migrating plume [PDF]

open access: yes, 2020
Anomalous topographic swells and Cenozoic volcanism in east Africa have been associated with mantle plumes. Several models involving one or more fixed plumes beneath the northeastward migrating African plate have been suggested to explain the space-time ...

FORMATION CONDITIONS OF AGATES [PDF]

open access: yesМинералогия, 2017
Agates are formed at various temperatures, which covers a wide range from those of basaltic and andesitic melts (above 1100 °С) to several tens of centigrade, but at rather low pressures. Their formation in liquid mafic magmas is indicated by correlation

Past-Forwarding Ancient Calamities. Pathways for Making Archaeology Relevant in Disaster Risk Reduction Research

open access: yesHumanities, 2017
Despite the alleged mastery of humans over nature, contemporary societies are acutely vulnerable to natural hazards. In interaction with vulnerable communities, these transform into catastrophes.

Weak Tectono-Magmatic Relationships along an Obliquely Convergent Plate Boundary: Sumatra, Indonesia

open access: yesFrontiers in Earth Science, 2018
The tectono-magmatic relationships along obliquely convergent plate boundaries, where strain partitioning promotes strike-slip structures along the volcanic arc, are poorly known. Here it is unclear if and, in case, how the strike-slip structures control
