Noun

aa (uncountable)

1. (volcanology) A form of lava flow associated with Hawaiian-type volcanoes, consisting of basaltic rock, usually dark-colored with a jagged and loose, clinkery surface. Compare pahoehoe. [From 19^th c.]
   • 1859, R. C. Haskell, American journal of science and arts, series XXVIII

     We...saw ‘pahoihoi’ or solid lava forming, and also ‘aa’ or clinkers.

   • 1944, Charles A. Cotton, Volcanoes as landscape forms:

     Cooling and solidification frequently takes a different course [...] in lava flows, producing the clinker-like ‘aa’ lava.

   • 1981, Hilo Lava Flood Control: Environmental Impact Statement, page 194:

     Both pahoehoe and aa lava flows are common on the upper slopes of Mauna Loa with a preponderance of aa flows found at the lower elevations.
