Abstract
Two new ordinary chondrites were found about 40 km west of Albuquerque, New Mexico. Correo is an H4 chondrite with distinct chondrules and major olivine (Fo81.4), orthopyroxene (En82.3) and plagioclase (An12). Suwanee Spring is an L5 chondrite with few distinct chondrules and a highly recrystallized matrix. Major minerals are olivine (Fo75.4), orthopyroxene (En77.7) and plagioclase (An9). The metallic Ni‐Fe phases of both meteorites are typical of slowly‐cooled ordinary chondrites.
