| Abstract: | A single stone of 52.99 g was found 30 km west of the Old Myrtle Springs homestead on the Lake Torrens Plains, (30° 27′ 13.8″ S, 137° 59′ 24.6″ E). The chondrules in the meteorite are well defined and the dark matrix consists of fine olivine and pyroxene grains. Olivine (Fa 17.2 ± 0.6), orthopyroxene (Fs 15.7 ± 0.7Wo1.8+0.8), clinopyroxene (Wo 22 ±2.0Fs14 ± 1.0), troilite and chromite are present. Radial pyroxene chondrules, porphyritic pyroxene chondrules, granular olivine-pyroxene porphyritic and olivine-pyroxene chondrules are abundant in the meteorite. Cryptocrystalline pyroxene chondrules and pyroxene-olivine chondrules are rare. Based on texture and mineral chemistry, the Myrtle Springs meteorite is classified as an H4 chondrite of shock stage S1-2, weathering grade W4. |
