Radiogenic Isotope Geochemistry
2016Isotopes provide important information on many geological processes, with key relevance to the mining and petroleum industries, yet the techniques to obtain, process and interpret the data can be complex to master. This accessible book provides broad coverage of radiogenic isotopes in geochronology and geochemistry, explaining the basic principles and ...

Production and Distribution of Radiogenic Isotopes
2012At present, more than 20 long-lived radioisotopes of heavy elements are known to exist in the Earth’s crust. These are evidence of the gigantic processes which resulted in the formation of chemical elements in our galaxy. The main characteristics of these elements are shown in Table 16.1.

The third edition of Radiogenic Isotope Geology examines revolutionary changes in geochemical thinking that have occurred over the past fifteen years. Extinct-nuclide studies on meteorites have called into question fundamental geochemical models of the Earth, while new dating methods have challenged conventional views of Earth history. At the same time,

Radiogenic and Stable Isotopes, Fluid Inclusions
2019Samarium and Nd isotope data are used to provide information on the source of melts, as well as to determine the age of the rocks. Several samples yield extreme high 147Sm/144Nd ratios of >0.3, indicating extreme fractionation of the REE. This is also reflected in their calculated present day eNd values of eNdt = 0 at >40.0.

Fluids and Radiogenic Isotopes
During water-rock interaction, several processes occur: coupled dissolution-reprecipitation, open-system reaction with formation of a compositionally different mineral, and Fick's Law diffusion in an inert matrix. All of these processes modify the stable and radiogenic isotopic compositions of the minerals.openaire +1 more source
