Re–Os isotopic constraints on magma mixing in the Peridotite Zone of the Stillwater Complex, Montana, USA

A study was undertaken to better constrain variation in Os initial isotopic ratios within and between chromite layers of the Peridotite Zone of the Stillwater Complex in Montana and in its source magmas, using Re-Os isotopic analysis of separated chromites from chromite layers and from silicate cumu...
