Petrography and mineral chemistry of two plagioclase-olivine inclusions (POIs) and two typical Ca-, Al-rich inclusions (one melilite-spinel-rich inclusion and one spinel-pyroxene-rich inclusion) from Ningqiang and the Grove Mountains (GRV) carbonaceous chondrites, respectively, were studied.POIs have the characters of mineral modal compositions of olivine-rich and melilite-absence, and they probably represent intermediate assemblages between typical refractory inclusions and chondrules. The petrography and mineral chemistry characters indicate that melilite-spinel-rich inclusion and spinel-pyroxene-rich inclusion are likely assemblages of solar nebular condensates, and POIs are crystallized from melts.oft-com:office:office" />
