Biolaminated Siliciclastic Deposits

Abstract

“Biolaminated deposits” (Gerdes and Krumbein 1987) originate from microbial growth and activity interacting with environmental, physical and chemical processes like sedimentary deposition and mineral precipitation. The resulting “primary” sedimentary structure was named “growth bedding” by Pettijohn and Potter (1964), with clear reference to in situ formed limestones and with “stromatolitic bedding” as the most prominent example (see also Pettijohn 1975).
