These meteorites are characterized by a high abundance of chondrules, small round mineral grains, and they have experienced different levels of metamorphism. Type 4 meteorites have undergone metamorphism that homogenized certain mineral compositions, while type 5 meteorites have undergone more extensive changes, including the conversion of specific minerals and blurring of chondrule outlines.
The Northwest Africa 4098 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.
