Оценочная стоимость
$ 200 000 – 300 000
The cut face of this slice reveals a galaxy of inclusions and minerals in a fine grained matrix. The low average concentrations of FeO and Th indicate this sample originated in the feldspathic lunar highlands. Its primary minerals are olivine gabbro clasts consisting predominantly of coarse-grained calcic plagioclase, pigeonite, olivine with accessory merrillite, ilmenite, chromite, baddeleyite, rare zirconolite, a silica polymorph, K-feldspar, kamacite, and troilite. The result of the ongoing bombardment of the Moon’s surface by meteorite impacts prior to the collisionresponsible for launching this rock to Earth.
Christie's would like to thank Dr. Alan E. Rubin at the Department of Earth, Planetary, and Space Sciences, University of California, Los Angeles for his assistance in preparing this catalogue.
