Jan 13, 2011 · Pigeonite is a mineral that can be found in basaltic eucrites and undergoes exsolution of augite upon cooling below the solidus. AI generated definition based on: …

Jan 15, 2025 · Based on textural feature and compositional calculation of pyroxene, we suggest that the coarse-grained orthopyroxene was inverted from primary pigeonite and NWA 8326 …

Aug 1, 2012 · The presence of zoned pyroxenes with cores of pigeonite supports the inference that komatiites in the Pioneer Complex solidified from anhydrous partial melts. During …

Apr 15, 2004 · A series of experiments on a synthetic, pigeonite-saturated, basaltic shergottite were carried out to constrain the variation of D(Eu/Gd)pigeonite/mel…

Jun 15, 2020 · Experimental determinations of trace element partitioning between plagioclase, pigeonite, olivine, and lunar basaltic melts and an fO2 dependent model for plagioclase-melt …
