THREE NATURAL ZIRCON STANDARDS FOR U‐TH‐PB, LU‐HF, TRACE ELEMENT AND REE ANALYSES 论文

摘要

We report here the results of a study to develop natural zircon geochemical standards for calibrating the U‐(Th)‐Pb geochronometer and Hf isotopic analyses. Additional data were also collected for the major, minor and trace element contents of the three selected sample sets. A total of five large zircon grains (masses between 0.5 and 238 g) were selected for this study, representing three different suites of zircons with ages of 1065 Ma, 2.5 Ma and 0.9 Ma. Geochemical laboratories can obtain these materials by contacting Geostandards Newsletter.
