Stable isotope Geochemistry

چکیده
This review is intended principally to be a reasonably comprehensive bibliography. It covers papers by workers in stable isotope geochemistry in the United States that have been published or presented at national meetings since the last quadrennial report. The titles of the papers in the bibliography are in most cases indicative of the general content, so only the highlights are described below. showed that with •13C • --7, the 'graphitic' carbon was enriched in 13C by 10-15%o relative to the rest of the carbon in the meteorite. The •13C values are highly variable, even within a single meteorite or in a single nodule within a meteorite.

Isotope Fractionation Processes of Selected Elements
The foundations of stable isotope geochemistry were laid in 1947 by Urey’s classic paper on the thermodynamic properties of isotopic substances and by Nier’s development of the ratio mass spectrometer. Before discussing details of the naturally occurring variations in stable isotope ratios, it is useful to describe some generalities that are pertinent to the field of non-radiogenic isotope geoc...

متن کاملA Review of Mg Isotope Analytical Methods by MC-ICP-MS
Application of multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS) has led to big breakthrough of analytical methods for metal stable isotopes, resulting in rapid progresses in non-traditional stable isotope geochemistry. As a new geological tracer, Mg isotopes have been widely applied in studies of almost all important disciplines of geochemistry. High precision Mg isotope...
