Isotope Geochemistry. In isotope geochemistry, our primary interest is not in dating, but using the time-dependent nature of isotope ratios to make inferences about the nature of reservoirs in the Earth and their evolution..

COMMON plumeswere initially thought to consist of primitive mantle (e.g., Schilling, 1973). As we found, mixing be-tween primitive and depleted mantle can explain the Sr and Nd isotopic compositions 286S Montani and Y MishimaIn this study we collected Nuta in situ by gentle means Nuta trap The purpose of thisinvestigation was to follow the Nuta decomposition and to evaluate the contribution of Nu in Cyprus Precipitation.
