Lithology description: heterotopic limestone, micritic, with bituminous facies, argillaceous layers, dolomitic layers, and neraster marls.
Environment:	shallow subtidal indet.
Geology comments: carbonate platform with quiet sedimentation, eventually probably stagnant, shallower, and anoxic at depth. Cyclic carbonate sedimentation evident, as well as supratidal erosion. Sequence from intertidal transgressive, to subtidal, to intertidal regressive phases.
