Abstract
The rhenium (Re) and osmium (Os) isotope systems have long been recognized as effective tools to directly date mineralization and trace the source of metals. In general, 0.4 g of pyrite was dissolved by 11 mL of inverse aqua regia in a 30-mL Carius tube. Larger volumes of acids and a larger Carius tube were required if the sample weight was over 0.4 g. Herein we present an improved dissolution process of the Carius tube digestion method by...
