More Evidence for Multiple Meteorite Magmas. Antarctic meteorite Graves Nunatak 06128/9 has abundant sodium-rich (Ab 82-85 ) plagioclase. Its oxygen isotopic composition suggests it could be related to brachinites. More Evidence for Multiple Meteorite Magmas.

More Evidence for Multiple Meteorite Magmas Antarctic meteorite Graves Nunatak 06128/9 has abundant sodium-rich (Ab82-85) plagioclase. Its oxygen isotopic composition suggests it could be related to brachinites. http://www.psrd.hawaii.edu/Feb09/asteroidalMagmas.html
More Evidence for Multiple Meteorite Magmas Brachinites could be residues after partial melting produced GRA basaltic magmas. GRA samples have REE concentrations similar to those produced by partial melting experiments on an L6 chondrite. http://www.psrd.hawaii.edu/Feb09/asteroidalMagmas.html
