Scientific paper

A suite of basaltic rocks sampled over a vast exposure and stratigraphic thickness in the Deccan traps has been investigated for Os isotopic systematics. The results plot on a very well defined Re-Os isochron corresponding to an age of /65.6+/-0.3 Ma (/2σ uncertainty). This age is in excellent agreement with previous K-Ar and Ar-Ar data. Os data also imply a short duration of volcanism, which should have important implications on mantle geodynamics. The 187Os/188Os initial ratio is typically chondritic: /0.12843+/-0.00047 (/2σ) and indicates that metasomatism and crustal contamination played only a very minor role in the Re-Os budget during formation of the Deccan traps.
