Yamato 791537 is considered a “Valid” meteorite. “Valid” meteorites are typical meteorites with average weathering, while “relict” meteorites are those that have been extremely altered, either due to weathering over time or human intervention.
Yamato 791537’s official classification is H3.6. The classification “H3.6” refers to a specific type of meteorite known as an ordinary chondrite from the H group. This meteorite falls into the petrologic type 3 category, indicating that it has numerous chondrules, minimal alteration due to water, and distinctive characteristics in its mineral composition, including monoclinic low-Ca pyroxene with twinning. Ordinary chondrites are a major class of stony meteorites, recognized by their unique elemental ratios, specific oxygen isotopes, and a significant proportion of chondrules in their composition.
The Yamato 791537 meteorite is a “Found” meteorite. Meteorites are classified as “falls” if they were observed falling and recovered, while “finds” are those discovered later, often weathered by longer exposure to Earth’s environment and without a record of being seen as they fell.
