The Euganean Hills of North East Italy have long been recognised as an area characterized by a higher than average natural radiation background. This is due to two main reasons: a) primary lithogenic radiation due to rhyolitic and trachytic outcrops, which are “acidic alkaline” magmatic rocks potentially enriched in uranium and thorium; b) secondary sources related to a geothermal field – widel...

Rock glaciers are common geomorphic features in alpine landscapes and comprise a potentially significant but poorly quantified water resource. This project focused on three complementary questions germane to rock glacier hydrology: 1) Does the composition of meltwater vary from year year? 2) How dependent is lithology? And 3) does presence catchment change stream chemistry? To address these que...

Abstract Mason Spur is a deeply eroded Middle Miocene to Pleistocene (c. 13 0.37 Ma) volcanic complex in southern Victoria Land, within the West Antarctic Rift System (WARS). The oldest rocks include large volume of trachyte ignimbrites that provided abundant detritus recovered McMurdo Sound drill cores. together with early-formed intrusions were strongly deformed during substantial caldera col...

Eocene intermediate to felsic subvolcanic rocks of the Torud-Ahmad Abad magmatic belt (TAMB), in northern part Central Iran zone, are exposed between Torud and Ahmad regions South-Southeast Shahrood. These igneous include hypabyssal dacite, trachyte, andesite, trachy-andesite, basaltic andesite; they mainly composed phenocrysts microcrystalline groundmass pyroxene, amphibole, plagioclase, with ...

Abstract Mineral chemistry, zircon U-Pb geochronology, and elemental Sr-Nd-Pb-Hf-O isotopic data for the Early Cretaceous volcanic rocks from Dabie East Qinling orogens of China constrain reworking history Yangtze crustal materials in North lithosphere. These provide new insights into recycling deepsubducted mantle transformation process continental subduction to collision. Our show that are ch...
