The geology and petrology of the Apollo 11 landing site

Geochemical and petrologic data indicate that the 73 Apollo 11 basalts thus far identified can be divided into five petrologic groups (A, B1, B2, B3, D) which must represent at least five separate igneous cooling units. These five igneous bodies range in age from 3.90 b.y. to 3.60 b.y. Photogeologic studies indicate that three mare units are present, and that the lunar module set down on the oldest of the three. The exposure age data suggest that the high-K flow is the surficial rock type at the landing area, and is, therefore, probably the oldest of the three mare units. By examining the size frequency distribution and the inferred cooling rates of the individual samples, it is possible to calculate the formation thicknesses within the 30-m-deep West Crater. This suggests that A = 9 m, B1 = 2 m (and may be an ejecta blanket), B2 is equal to or greater than 8 m, and B3 = 6 m.
