The rhenium-osmium (Re-Os) dating technique is uniquely able to date directly sulfide minerals and some natural metals because both elements have strongly. Reliable dating of sediments has several applications in petroleum systems. Rhenium (Re) and Osmium (Os) are both siderophilic (meaning. The information presented below briefly outlines how Chemostrat is utilising two of these techniques, i.e., the Rhenium - Osmium (Re - Os) isotopic dating. journal homepage www.elsevier.comlocateprecamres. Structural characteristics and ReOs dating of quartz-pyrite veins in the Lewisian Gneiss Complex, NW. Methods and results Re-Os dating of molybdenite is described in Stein et al. (2001). We present the results of high precision Re-Os age determinations for two. group of elements and the two isotopic systems (PtOs and ReOs) they contain provide a view of Earth. A recent extension of ReOs dating of mantle. The radioactive decay of 190Pt to 186Os has a half-life of 6.5(3)1011 years (which is longer than the age of the.

INTRODUCTION. Determining the composition and age of the lower crust is key to understanding the bulk com- position of continental crust and the mechanism. We describe the principle of the Re-Os dating technique and the thermal ionization phenomena which lead to high precision isotope analysis on NTIMS. Precise ReOs ages of organic-rich mudrocks and the Os isotope. timescales, and establish the importance of the Re-Os dating technique for. rhenium-osmium dating Method of determining the age of the important ore. The isotope rhenium-187 ( 187Re) decays to osmium-187 ( 187Os) having a.
