14301 (79) Regolith Breccia
We would like to thank the following for the use of this sample:
14301 is a fragmental breccia with about 20% clasts >1 mm, abundant glass, agglutinates and a fine matrix. Most class are lithic fragments, although four types of glass and a small proportion of chondrules are also reported. It is considered to be a regolith or soil breccia. However, in various properties (C content, 4He, Al etc.) it is transitional between the Fra Mauro breccia and typical Apollo 14 regolith breccia.
The sample weighed 1360.6 grams before analysis. It could not be dated accurately but is about 4 billion years old.
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.
