[sup 36]Cl and [sup 10]Be cosmogenic exposure age data for the Black Rock basaltic lava flow, Lunar Crater volcanic field, Nevada, imply an emplacement age of [approximately] 38 [+-] 10 ka. [sup 36]Cl data for the 600 ka flow north of the Lunar Crater maar are consistent with (1) an apparent erosion rate of [approximately] 3 m/m.y., (2) a model of desert pavement formation in which basalt clasts eroded from the flow remain on the surface of the eolian-derived sediments that mantle the flow, and (3) the early formation of the eolian-derived sediment mantle. 20 refs., 3 figs., 2 tabs.
