英文摘要	Ca-, Al-rich inclusions (CAIs) are the earliest assemblages of the solar nebula, and they contain information of early solar nebula. They are the probe of studying the origin and evolvement of early solar nebula. The formations of CAIs include gas-solid condensation, crystallization from melting or partial melting and high-temperature residues. Some CAIs are often surrounded by thin mono- or bi-mineral rims known as Wark-Lovering (W-L) rims. CAIs and their W-L rims offer a record of conditions during the earliest stages of Solar System formation in the inner regions of the solar accretion disk. However, the W-L rim forming processes themselves main poorly understood. In this paper, we report the petrography, mineral chemistry and oxygen isotopes characteristics of three CAIs (C#1 : plagioclase-olivine inclusion; GRV 022459-2RI5: type A inclusion; GRV 021579-3RI5: spinel-rich spherule inclusion) and their W-L rim. C#1 inclusion was crystallized from melts. The oxygen isotopes of W-L rim are similar with the interior minerals, and its argue for a same 16 0-rich reservoir of W-L rim and interior minerals of C#1 inclusion. The petrography and mineral chemistry argues that GRV 022459-2RI5 was likely assemblages of solar nebular condensates, and the W-L rim of the CAI was the latest assemblages of nebular condensates. GRV 021579-3RI5 was crystallized from melts, and the W-L rim of the spinel-rich spherule was the latest assemblages from the melts.
