Description: 

14055 is a friable blocky, sub-angular to sub-rounded rock lightly covered with glass-lined zap pits. It is a fine-grained clastic rock with 5 to 15% of sub-rounded light-coloured clasts in a medium-grey matrix. Lithic fragments include both granulite and basaltic compositions. A high percentage of agglutinates is also reported.

The sample weighed 111 grams before analysis. It has not been dated.

Rotation 1 shows a spherical glass globule, whereas rotation 2 shows a relatively large (and unusual) ropy glass fragment.
