trace and rare earth element geochemistry of croatian thermalwaters

concentrations of 42 trace elements, including rare earths, in croatian thermal waters wereinvestigated. originating from different parts of croatia, i.e. different types of aquifers, studied thermal watersprovide insight into the range of concentrations of broad spectrum of elements in croatian thermal waters.covering a wide range of temperature (30 - 92 °c), studied thermal waters are general...

Trace Element Geochemistry of Peridotites from the Izu - Bonin - Mariana Forearc , Leg 125

Trace element analyses (first-series transition elements, Ti, Rb, Sr, Zr, Y, Nb, and REE) were carried out on whole rocks and minerals from 10 peridotite samples from both Conical Seamount in the Mariana forearc and Torishima Forearc Seamount in the Izu-Bonin forearc using a combination of XRF, ID-MS, ICP-MS, and ion microprobe. The concentrations of incompatible trace elements are generally lo...

Trace Element Geochemistry of Biogenic Sediments from the Western Equatorial Pacific

Twenty-seven surface samples ofbiogenic sediment, including radiolarian, nannofossil, and foraminiferal oozes from the Western Equatorial Pacific have been analyzed for potassium, magnesium, iron, rubidium, strontium, barium, chromium, cobalt, nickel, copper, and zinc by rapid instrumental techniques. Interelement associations have been evaluated with the use of a computer-compiled matrix of co...
