Research was conducted in order to assess potential exposure to asbestos while harvesting firewood from amphibole-contaminated trees near Libby, MT, USA. Three firewood-harvesting simulations took place in the summer and fall of 2006 in the Kootenai Forest inside the US Environmental Protection Agency (EPA) restricted zone surrounding the former W.R. Grace vermiculite mine. Another simulation w...

New occurrences of xenolithic alkaline rocks from three East African volcanoes are described. Micro-ijolites and alkali pyroxenites occur in the carbonate-rich tufts and lavas of Mount Elgon; kaersutite-rich pyroxenites and a suite of fenitized basement rocks in the caldera flows of Mount Meru, and apparently unique melanocratic hortonolite nepheline syenites in the central foyaite plug of Moun...

The Mashhad ultramafic complex with a Permo-Triassic stratigraphic age is exposed at the NE of Binaloud Mountain and the SW to NW of Mashhad city. This area is mainly composed of mafic and ultramafic rocks, metamorphosed carbonate and pelitic rocks and granitoids in a NW- SE trend. Serpentinized amphibole-peridotites are the main types of ultramafic rocks in this area. Minerals in these rocks i...

In Finland, unlike other countries, anthophyllite asbestos has been widely used due to its domestic production in 1918-1975. In this particular context, the aim of the present study was to analyse the relationship between asbestos bodies (ABs) in bronchoalveolar lavage (BAL) fluid and the concentration of ABs and the different amphibole asbestos fibres in lung tissue. Sixty five BAL lung tissue...

Samples of a garnet granulitc from the mafic border units of the Lake Chatuge, Georgia alpine peridotite body were found to contain lamellar intergrowths of a pargastic amphibole in augite having the typical appearance of an exsolution feature. Single crystal X-ray diffraction, optical, electron microprobe and conventional and analytical electron microscopic studies have provided data limiting ...

Coexisting hornblende and cummingtonite in an amphibolite near Peliwali have been analysed. The rock formed by Fe-Mg addition and Ca removal from pre-existing amphibole quartzites within the altered wall rocks surrounding sulphide lodes. The amphibole compositions are controlled by the bulk composition of the rock. The Mg/(Mg+Fe 2+) ratio of the hornblende (o.66) is only slightly higher than th...

This paper describes a case control study investigating separately the lung cancer risk of exposure to chrysotile and to amphiboles. Logistic regression models were used to estimate separate exposure-response curves for the two fibre types, controlling for smoking. In the period longer than 15 years before lung cancer diagnosis, smokers above the 90th percentile of cumulative exposure to either...

Compared to the Earth, its Moon is strongly depleted in volatiles, and its interior is generally treated as anhydrous. The internal volatile content of the Moon remains a critical control on its petrogenesis, and can be re-assessed in light of current interest in the Moon. One tool in this assessment is chemical (and isotopic) analysis of minerals that could contain volatile elements. One volat...

Abstract We present microbeam major- and trace-element data from 14 monzodiorites collected the Malaspina Pluton (Fiordland, New Zealand) with goal of evaluating processes involved in production andesites lower arc crust. focus on relict igneous assemblages consisting plagioclase amphibole lesser amounts clinopyroxene, orthopyroxene, biotite quartz. These are heterogeneously preserved crust wit...
