Krasheninnikov Caldera (Eastern Kamchatka): age and magnitude of eruption
New data on the composition of the pyroclastic deposits of the Krasheninnikov caldera allowed us to correlate it to the previously studied tephra horizon Geys30, which until recently was erroneously attributed to an eruption within the Geysernaya caldera.

Guide to the geology of Bradgate Park and Swithland Wood, Charnwood Forest [PDF]
Charnwood Forest is one of the few parts of England where there are exposures of ‘basement’ rocks dating back to Precambrian time. Its locally rugged topography is caused by these highly resistant rocks protruding as craggy knolls through a surrounding ...

Debris Flow and Pyroclastic Flow at Unzen Volcano
Unzen Volcano began to erupt in November 1990 after 198 years of dormancy and has remained active. Continuous growth of a lava dome and falls of lava rocks have resulted in frequent pyroclastic flows. Since a great volume of volcanic material has been deposited and scattered by the pyroclastic flows, debris flows have frequently occurred along the ...

Once despised now desired: innovative land use and management of multilayered Pumice Soils in the Taupo and Galatea areas, central North Island, New Zealand [PDF]
The tour brings together innovative land use change and management associated with dairy farming, and land-based effluent disposal, on weakly weathered and multi-layered, glass-rich, Pumice Soils (Vitrands) in the Taupo and Galatea areas.

Volcanological constraints of Archaean tectonics [PDF]
Volcanological and trace element geochemical data can be integrated to place some constraints upon the size, character and evolutionary history of Archean volcanic plumbing, and hence indirectly, Archean tectonics.

A study of stability analysis of pyroclastic covers based on electrical resistivity measurements
Usually, the degree of stability of a slope is quantified by the Factor of Safety whose values depend on physical and mechanical soil properties analyzed on samples of much reduced sizes or referring to very small soil volumes around porous probes.

Calcite-saturated natrocarbonatites: composition, crystal morphology, and weathering
Interpretation of calcite-dominated fossil carbonatite volcanoes is complicated by the instability of many igneous carbonatite materials on Earth’s surface.

Igneous processes within late Precambrian volcanic centres near Whitwick, northwestern Charnwood Forest [PDF]
Precambrian rocks in northwestern Chamwood Forest differ markedly from their lateral equivalents to the east and south. They are subdivided into the Whitwick Volcanic Complex, of massive to intensely brecciated high-silica andesites and porphyritic ...

Proceedings of a workshop on Lunar Volcanic Glasses: Scientific and Resource Potential [PDF]
This workshop on lunar mare volcanism was the first since 1975 to deal with the major scientific advances that have occurred in this general subject, and the first ever to deal specifically with volcanic glasses.
