From:Occupational and Environmental Medicine (Vol. 59, Issue 7) Peer-ReviewedBackground: The Soufriere Hills, a stratovolcano on Montserrat, started erupting in July 1995, producing volcanic ash, both from dome collapse pyroclastic flows and phreatic explosions. The eruptions/ash resuspension...

From:PLoS ONE (Vol. 7, Issue 11) Peer-ReviewedBackground Preservation of fossil vertebrates in volcanic rocks is extremely rare. An articulated skull (cranium and mandible) of a rhinoceros was found in a 9.2±0.1 Ma-old ignimbrite of Cappadocia, Central...

From:Canadian Journal of Earth Sciences (Vol. 57, Issue 12) Peer-ReviewedThe Xiaorequanzi Cu--Zn deposit is in the westernmost part of East Tianshan Terrane in northwestern China. The deposit is unique in the region being a volcanogenic massive sulphide (VMS) deposit located near a zone (or...
-
From:Canadian Journal of Earth Sciences (Vol. 55, Issue 5) Peer-ReviewedWe present thirty new laser ablation inductively coupled plasma mass spectrometry U-Pb zircon dates for intermediate to silicic plutons of the Northern Cascade Arc with emphasis on the Chilliwack batholith--Mount Baker...
-
From:Contributions to Mineralogy and Petrology (Vol. 164, Issue 3) Peer-ReviewedProtoliths of highly metamorphosed gneisses from the Erzgebirge are deduced from the morphology, age and chemistry of zircons as well as from whole rock geochemistry and are compared with lower-grade rocks of Lusatia....
-
From:Contributions to Mineralogy and Petrology (Vol. 165, Issue 6) Peer-ReviewedAdakites have been found in various tectonic settings, since the first report for the distinct lavas as a product of slab melting in Adak Island by Kay (J Volcanol Geotherm Res 4:117-132, 1978). In this study, we...

From:Nature (Vol. 496, Issue 7446) Peer-ReviewedEarth recycles--but it takes its time. Chemical remnants of the rigid surface plates that plunge deep into the planet's interior at subduction zones can eventually resurface on distant volcanic islands. But the process...
-
From:Contributions to Mineralogy and Petrology (Vol. 170, Issue 2) Peer-ReviewedMajor and trace element compositions with Sr-Nd isotopic ratios, as well as Ar-Ar radiometric ages of the Miocene volcanic rocks from the Neogene units around Simav region (western Anatolia), are used to discuss the...
-
From:Earth Surface Dynamics (Vol. 9, Issue 2) Peer-ReviewedSurficial mass wasting events are a hazard worldwide. Seismic and acoustic signals from these often remote processes, combined with other geophysical observations, can provide key information for monitoring and rapid...
-
From:Construction and Building Materials (Vol. 28, Issue 1) Peer-ReviewedABSTRACT In this study, production of mortars with disposable polyethylene bottles, but without cement, was investigated. The disposable polyethylene bottles were crushed and converted into fiber formation. Then...
