A Crustal Rock Clast in Magnesian Anorthositic Breccia, Dhofar 489 and Its Excavation from a Large Basin
From the older Ar-Ar age (4.27 Gyr) and the presence of a spinel troctolite clast in Dhofar 489, we propose that a large basin formation other than Imbrium may have mixed deep crustal rocks and "pure" anorthosites to produce a magnesian breccia.
