Open publisher page 1 citations

Abstract

Sample 67215c is a ferroan anorthosite clast with an age of 4.4 Ga and a positive Nd. The sample has a well preserved microcumulate texture. Relatively rapid cooling rates coupled with preserved pigeonite are consistent with a shallow (<1 km) origin. Additional information is contained in the original extended abstract.
