Macroscopic Description - Kathleen McBride
The exteriors of these meteorites are rough, blackish in color with a few oxidation halos. There are some smooth areas that are lighter or more grayish in color than the rougher areas. Very small patches of rough, black fusion crust are present. The interiors are dark gray matrix with vesicles.
Thin Section (,2) Description - Tim McCoy and Linda Welzenbach
The sections are so similar that a single description suffices. They consist of a matrix of individual mineral fragments up to 100 microns in a melt-textured matrix with rounded to ellipsoidal metal-sulfide blebs. LAR 06298 also exhibits larger (up to several mm) unmelted chondritic fragments with rare relict barred olivine chondrules. Olivine is Fa29, pyroxene is Fs23. The meteorites are LL chondrite impact melt breccias.
