Abstract
The term "griottes" has been used loosely to describe carbonate rocks from the uppermost Devonian of the Pyrenees of southern France. Three types are distinguished among the Famennian griottes of the central Pyrenees, the Corbieres range, and the Montagne Noire--intraformational conglomerates, rocks with alternating limestone and shale layers showing evidence of submarine slumping during deposition, and more or less massive limestones. All gradations exist between these three main types. The griottes are variable in space as well as time. They are interpreted as representing deposition in a marine environment in which there was a tendency toward emergence, accompanied by minor slumping and local development of rocky reefs. In any case, they are not deep-sea deposits, as previously held.
