14049 (39) Regolith breccia
 >View Microscope
Fact sheet
Description: 

14049  is a very fine-grained clastic rock having less than 1 % of sub-rounded light-coloured clasts in a medium-grey matrix. It has a high carbon content and surely was derived from local soil as an “instant rock”. It has been described as a regolith breccia. 14049 has a high percentage of brown glass and agglutinates. Small fragments of plagioclase-rich granulite are also common.

The sample weighed 200.1 grams before analysis. It has not been dated.

The mounting resin of this thin section has deteriorated over time and now contains clusters of feathery crystallites within and around the margins of the thin section.
