Grove Mountains 99019’s official classification is L3. Meteorites classified as “L3” are ordinary chondrites from the L group that exhibit characteristics of petrologic type 3 chondrites. These meteorites are known for having abundant chondrules, low levels of aqueous alteration, and mineral compositions that are not fully equilibrated. Some of the low-Ca pyroxene grains may have monoclinic structures and display polysynthetic twinning, and they may belong to different subtypes within the type 3 category based on their degree of metamorphism.
The Grove Mountains 99019 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.
