14063 is a friable breccia having about 40% of sub-angular to sub-rounded clasts in a very light-grey matrix. Dark clasts are subordinate to light clasts, and there is some glass. It is a polymict breccia composed of a mixture of lithic and mineral clasts in a fine-grained matrix with seriate grain size distribution. Plagioclase is the dominant mineral, with subordinate pyroxene, olivine, ilmenite, spinel and metallic iron grains.
The sample weighed 135.45 grams before analysis and is 3.81-3.94±0.02 billion years old (Ar/Ar).
Rotation 1 shows a fractured black glass breccia clast containing a pink spinel crystal, whereas rotation 2 shows a polymict black glass clast.
The mounting resin of this thin section has deteriorated over time and now contains clusters of feathery crystallites around the margins of the thin section.

The Apollo 14 landing site was in a region formed by impact-basin debris.
Most of the 42 kilograms of rocks and soil collected on Apollo 14 are breccias (rocks that are composed of fragments of other, older rocks). In some cases, the rock fragments that form a breccia are themselves breccias. Such rocks obviously have experienced complex histories with multiple generations of impact events. Some breccias were heated enough that some of the material in the rock was melted.
Apollo 14 was launched on 31 January 1971.
