14076 (5) Fragmental breccia
We would like to thank the following for the use of this sample:
14076 was one of 7 small rocks collected from the bottom of a 30 cm deep trench. It has two distinct lithologies with sharp contact; one is brownish like most other Apollo 14 soil breccias, and one is greyish and very aluminous. The aluminous lithology is thought to be an exotic highland regolith and is quite unusual when compared with other Apollo 14 breccias. The aluminous part of 14076 is found to have large glass spheres and tiny glass spheroids of GASP (gas-associated spheroidal precipitates). A new lunar mineral, yoshiokaite, is also reported in this lithology.
The sample weighed 2 grams before analysis. It has not been dated.
Our thin section has been gold coated for SEM investigation. Most has been cleaned off, but fragments remain in fractures.
