LL3.00 Meteorite Classification

Class Description

The classification “LL3.00” refers to a specific type of ordinary chondrite from the LL group. These meteorites are characterized by their low iron and metal content, fairly large chondrules, and oxygen isotope compositions that differ from other ordinary chondrites. They are also classified as petrologic type 3, indicating an abundance of chondrules, low levels of alteration, and unique mineral features like monoclinic low-Ca pyroxene grains with twinning. The “LL3.00” classification specifically represents the least metamorphosed type 3 chondrites within this group.
