Foundered strata is a term used by the British Geological Survey in its maps and geological memoirs, and indeed by other authors, to describe rock strata which has collapsed due for example to the dissolution of underlying strata. Foundered strata may retain its original bedding more or less intact or else it may assume a chaotic structure in the process of collapse or indeed some intermediate state of disruption.
