Fact sheet
Description: 

Miller Range 05035 was found during the 2005-2006 ANSMET field season. The exterior has about 95% black, shiny fusion crust. The interior is pinkish-tan in colour with no rusting. The rock is moderately hard and has an unusual granular texture with a vague resemblance to granite. The texture is unbrecciated and is dominated by pyroxene grains (54–61%) along with large plagioclase feldspar crystals (25–36%) and accessory quartz, ilmenite, spinel, apatite and troilite.

The sample weighed 142 grams before analysis and two aliquots have been been dated at 3.91 and 3.85 billion years (Ar/Ar).
