AIMS To report the temporal pattern and change in trend of mesothelioma incidence in the United States since 1973. METHODS The Surveillance, Epidemiology, and End Results (SEER) programme of the National Cancer Institute has since 1973 provided annual age adjusted incidence for mesothelioma in representative cancer registries dispersed throughout the USA. SEER data are analysed to describe th...

This study reports the first detailed geochemical characterization of Kolumbo submarine volcano in order to investigate the role of source heterogeneity in controlling geochemical variability within the Santorini volcanic field in the central Aegean arc. Kolumbo, situated 15 km to the northeast of Santorini, last erupted in 1650 AD and is thus closely associated with the Santorini volcanic syst...

Experimental animal studies comparing asbestos and non-asbestos varieties of tremolite indicate tremolite asbestos is markedly more carcinogenic. By direct analogy, the differences in carcinogenicity between tremolite asbestos and non-asbestos prismatic tremolite should be the same for the other types of amphibole that also crystallize in the asbestos and non-asbestos habits. The earliest of th...

marbles containing high-pressure mineral assemblage was found from the sanandaj-sirjan metamorphic belt in the nahavand area in western iran.  the high-pressure marbles occur as small bodies or lenses within pelitic schist layers and show compositional banding of carbonate- and silicate- rich bands.  textural analysis revealed two metamorphic stages.  the early stage is testified by relicts of ...

The structure refinement of a hastingsite (CI 0.91 p.f.u.) from West Ongul Island, Liitzow-Holm Bay, East Antarctica, has been carried out in order to characterise the effect of CIon the crystal structure. The composition of the CI-rich hastingsite is KO.69Nao.26Ca1.99Mg1.09Fe2+ 2.71Fe3+O.92MnO.\l4 Tio.lOAI2.31Sis.R30220Ho.99Clo.91Fo.10with unit cell parameters a 9.962(3), b 18.283(7), c 5.372(...

Introduction: This study presents first experimental results on the effect of fluorine on near-liquidus phase equilibria of an Adirondack-class Martian basalt. The basis of this study is our previous work on anhydrous [1] and chlorine bearing [2] systems which has already shown that: 1) the Adirondack-class basalts are evolved liquid compositions [1] and 2) that chlorine has a large effect on l...
