Ordinary chondrite, unequilibrated (H3.4; S3; W2)
Found,1988; 26.39 g

The Allan Hills 88036 meteorite (or, ALH 88036 meteorite) is a very small but unequilibrated (primitive) meteorite found in Antarctica. In thin sections its most obvious constituents are the distinct chondrules of olivine and orthopyroxene (up to 800 µm in section). Barred, radial, and porphyritic types predominate, esp. barred olivine (BO). Unequilibrated olivine and orthopyroxene grains and feldspathic material are also found in the surrounding matrix. Fe-Ni metal and troilite are likewise found in the matrix and also at chondrule rims. Average olivine composition (Fa17.2) is characteristic of the H (high iron) ordinary chondrite group. Weathering grade (W2) is based upon the presence of moderate rustiness.

A relatively short cosmic ray exposure age of ~2 Ma is reported in Mokos et al.,2000.
