Sample No. MAC88199

Location: MacAlpine Hills

Dimensions (cm): 2.5 x 2 x 1.5

Field Number: 5743

Weight (g): 28.9

Meteorite Type: L3 chondrite

Macroscopic Description: Cecilia Satterwhite

Ninety-five percent of this unequilibrated chondrite is covered with black, frothy and pitted fusion crust. This chondrite is composed of brownish black matrix with abundant chondrules/inclusions that have a range in color from white to yellow to orange and a range in size from 0.1 to 0.3 mm.

Thin Section (,2) Description: Brian Mason

Chondrules and chondrule fragments are abundant, ranging up to 1.2 mm across, with one exceptionally large one 4.2 mm across. They are set in a dark matrix which contains a little nickel-iron and troilite, sometimes concentrated on the rims of chondrules. Microprobe analyses show olivine and pyroxene of variable composition: olivine, Fa1-29 (CV FeO is 55); pyroxene, is Fs2-23. The variability of olivine and pyroxene compositions indicates type 3, and the small amount of nickel-iron L group; hence the meteorite is classified L3 (estimated L3.4).
