14082 (48) Light matrix breccia
 >View Microscope
Fact sheet
Description: 

14082 is a blocky to slightly slabby, angular rock with a very rough surface. The sample is a very friable, fine-grained clastic rock with a few percent of subrounded dark clasts in a very light grey matrix. The matrix is porous and characterized by a seriate texture, with material ranging from the limit of resolution up to about 300 microns. The mineral clasts are plagioclase, pyroxene, olivine, ilmenite and colourless glass. Plagioclase (An70-96) is most abundant and only rarely shows undulatory extinction. Olivine and pyroxene are sub-rounded and less than 300 microns. The lithic clast population is dominated by poikilitic-textured impactites which contain plagioclase laths enclosed in pyroxene oikocrysts together with clasts of angular plagioclase. Several clasts of high-Al basalt and vitric-matrix breccia have also been reported.

14082 is paired with 14083.

The sample weighed 62.63 grams before analysis. It has not been dated.
