Distinct subsolidus cooling histories of Apollo 14 basalts.Study of the distribution of magnesium and ferrous iron over the M1 and M2 positions in pyroxenes from the basaltic rocks 14053 and 14310, aimed at an analysis of the subsolidus cooling history. The results obtained suggest that the subsolidus cooling of the basalt 14310 occurred at a depth of several meters in a coherent body of appreciable size. As for the 14053, the hot debris of which it was a part were deposited after the projection from the Imbrium basin; some smaller fragments, including 14503, cooled very rapidly in the cold Fra Mauro regolith by conduction.
