Folk's Classification

Folks classification of limestones based on the matrix/cement and the main lithological components. For example, a limestone with a micrite matrix containing mainly ooids would be Oomicrite. If the cement were sparite instead, then it would be an Oosparite. Folk used four main clast types: ooids, bioclast, peeloid and intraclast.
