The “H5” classification indicates a high-iron ordinary chondrite from the H group, characterized by its relatively small chondrules and siderophile elements, with oxygen isotope ratios nearing Earth’s values. This type 5 meteorite has undergone significant metamorphism, leading to a uniform composition of minerals like olivine and pyroxene, growth of secondary minerals, and less distinct chondrule features.
