Abstract The Rauer Group in East Antarctica is a typical high- to ultrahigh-temperature (HT–UHT) granulite-facies terrane. As UHT metamorphism has been recognized only Mg–Al-rich pelitic granulites from the Mather Paragneiss, regional extent of remains uncertain, which hindered our understanding genesis and tectonic setting Group. In this study, representative samples mafic granulite were selec...
Arc magmas originate in subduction zones as partial melts of the mantle, induced by aqueous fluids/melts liberated by the subducted slab. Subsequently, they rise through and evolve within the overriding plate crust. Aside from broadly similar features that distinguish them from magmas of other geodynamic settings (e.g., mid-ocean ridges, intraplate), arc magmas display variably high Sr/Y values...
There is a chrysotile mine in the central mountains of Cyprus but no other appreciable source of industrial asbestos. Hence the island was thought to offer ideal conditions to seek pure chrysotile induced mesothelioma. The first reported case was a village woman whose lung tissue contained amphibole asbestos fibres, which were later identified as tremolite. This began a search for the origin of...
Amphibolites in the studied area have upper Triassic age and seen with various rocks such as micaschiste, marble and metadolomite. These rocks with dark and green color contain minerals as hornblende, plagioclase, actinolite, tremolite and epidote that dark and light minerals were separated and seen as dark and light bands. Based on whole rock geochemical analysis, these rocks belong to sub-alk...
OBJECTIVES To describe asbestos-related mortality among manufacturing workers who expanded and processed Libby vermiculite that contained amphibole fiber. METHODS Standardized mortality ratio was calculated for 465 white male workers 31 years after last Libby vermiculite exposure. RESULTS Two workers died from mesothelioma, resulting in a significantly increased standardized mortality ratio...
