Fact sheet
Description: 

14250 is part of the Comprehensive Sample collected by Apollo 14. Samples 14169-14188 and 14250-14299 were acquired as a statistically significant set of small rock samples to petrographically characterize the distribution of rock types in the lunar regolith. The sample location was selected 100 to 125 metres west of the lunar module. A two to three metre diameter circle was marked and all of the walnut sized rocks on the surface within the circle were collected with tongs. Sample 14250 is a medium grey, blocky, sub-angular, moderately friable, seriate fragmental rock. Rotation 1 shows a composite clast and rotation 2 shows a greenish glass-rich area.

The sample weighed 1730 grams before analysis.
