 note = {P(論文), Hammadah al Hamra 126 (HAH 126) is a new ureilite recovered from the Sahara desert in 1995. This meteorite experienced fairly extensive weathering in the desert environment. Olivines in HAH 126 are more intensely reduced than those in other ureilites which have been studied to date. We have obtained a cooling rate of 0.1-0.7℃/hour for the reduction rims of olivines using diffusion calculations. This cooling rate is slightly slower than those for other ureilites. Rims of pigeonite grains in HAH 126 often show high-Ca contents. These Ca-rich materials resemble those which are present at olivine rims in Y-74123 ureilite. This fact suggests that Ca-rich melt was present at grain boundaries (H. OGATa et al.; Meteoritics, 25,195,1991).},
