Writeup from MN J18:
Y980703 R6 chondrite
Although the specimen is an unbrecciated chondritic meteorite, the modal abundance of chondrules is much lower than those of ordinary chondrites. The composition of olivine is clustered at Fa38-40. The coarse-grained matrix is recrystallized and abundant metamorphosed plagioclase occurs. Thus, it is an equilibrated Rumuruti chondrite, R6, and may be paired with Y980702 and Y980705, which show similar textures and have similar compositions. The shock stage of the specimen is very low because significant undulatory extinction is absent. | ||||||||
