Fact sheet
Description: 

14319 is a blocky, angular rock with a highly irregular surface. The rock is a coherent breccia that is broken apart along fractures. Clasts make up to 30 percent of the rock and dark clasts are by far the dominant type. Some of these have white clasts within them.

14319 weighed 211.6 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 around the margins of the thin section.
