Siliceous scoria droplets, measuring from 1 to 10 mm, from one late Pleistocene and four early Holocene
archaeological sites in northern Syria are compared to similar droplets previously suggested to be the
result of a cosmic impact at the onset of the Younger Dryas global cooling event. The !ndings demonstrate
that the presence of siliceous scoria droplets are independent of age and thus are not speci!c to the
beginning of the Younger Dryas. Occurrences have not been reported from natural deposits, but are
instead associated with buildings destroyed by !re and thus appear to be restricted to archaeological
sites. We therefore conclude that melting of building earth in ancient settlements can occur during !res
reaching modest temperatures. There is no evidence to suggest that siliceous scoria droplets result from
very high temperature melting of soil and are the result of a cosmic event.
