Stable isotope ratios of nickel, copper, and zinc are powerful tools for elucidating the biogeochemical cycling of trace metals in the ocean. However, analytical difficulties have impeded isotopic studies of these metals. We present a simple and r...
<p>We present the tellurium (Te) isotope compositions of the acid leachates and residues from three carbonaceous chondrites, namely, Allende, Murchison, and Tagish Lake. Most of the Te isotope compositions in the acid leachates and residues were i...

Precise Sr isotopic compositions in samples from sequential acid leaching experiments have been determined for three carbonaceous chondrites, Allende, Murchison, and Tagish Lake, together with those in the bulk aliquots of these meteorites. The ch...

We present a new method for precise isotope analysis of Te by thermal ionization mass spectrometry in negative ion mode (N-TIMS) along with an improved technique for chemical separation of Te from geochemical samples. In the chemical separation, T...
