摘要：
Microprobe analyses of fifty chondrules in the Sharps (H-3) chondrite showed three to contain essentially homogeneous, calcium-poor olivines. All three show textural evidence of recrystallization, which is subtle in two and pronounced in one. It is concluded that these chondrules were recrystallized before they entered Sharps. Although Sharps is an H-group chondrite, the recrystallized chondrules have olivine and pyroxene compositions appropriate to recrystallized LL-group chondrites. They thus suggest that low-iron material, with a complex previous history, was present at the place of formation of the H-group chondrites. © 1968.
