Close-up of a sawn slice, probably about 1 cm in longest dimension. Note the vesicular fusion crust along the upper left edge. The meteorite is a regolith breccia. Note that the clasts (1) come in all sizes and a variety of gray shades, (2) they are not rounded like beach pebbles, and (3) there is no layering.

Calcalong Creek

Wiluna District, Western Australia, Australia
Found: after 1960
Mass: 19 g

Lunar meteorite


A stone of 19 g was found by an Aborigine meteorite hunter in the Millbillillie strewnfield. It has a complete fusion crust, the interior shows a microbreccia with white angular clasts in a dark matrix (impact melt breccia, calculated from the bulk analysis: 50% anorthosite, 20% KREEP, 15% Luna- 16 type low-Ti mare basalt and 15% Sc-Cr-V components). Information and analysis, Fe/Mn = 73-78, KREEP pattern of REE, Dolores H. Hill, Lunar Planetary Laboratory, University of Arizona, Tucson AZ 85726, USA. See also, D. H. Hill, W. V. Boynton and R. A. Haag, Nature, 1991, in press. The main mass is with Robert Haag, P. O. Box 27527, Tucson, AZ 85726, USA.
