Description: 

14181 is a small chip of high-K, mare basalt. It has a sub-ophitic basaltic texture with prominent plagioclase laths partially intruding
clinopyroxene. Plagioclase varies in composition from An84-An94. Other phases include K-feldspar, ilmenite, chromite, troilite and metallic iron. 14169-14188 may be parts of 14303/4 as this kind of basalt is frequently found as clasts in Fra Mauro breccias.

The sample weighed 2.48 grams before analysis. It has not been dated.
