WebMay 11, 2016 · The classes within the Folk classification system are grouped into four overarching limestone types (Fig. 1 ). Grain-supported limestones comprising allochems cemented by sparry calcite cement and with an absence of micrite are termed sparry allochemical rocks. Folk's carbonate rock classification details the relative proportions of allochems in the rock and the type of matrix. The classification scheme covers most common carbonate rocks, however the more inclusive although less precise alternative, Dunham classification, may be preferred in some instances.

Folk, an influential sedimentary petrologist and Professor Emeritus at the University of Texas See more • Dunham classification • Gazzi-Dickinson method • QFL Diagram, similar to the QFR diagram of the Folk classification system. See more Folk's philosophy is that the name of a rock must convey as much information as possible without being a complete description. For this, he proposed five important properties of sandstones to use as defining characteristics. These five properties are: … See more
WebThe modified Folk Classification is pretty good for describing just the texture of the carbonate, based on the % of allochems, micrite, or spar. But people generally use the Dunham Classification with the Embry-Klovan modifiers more, because the name implies something about the depositional fabric. WebFolk, recognizing the three main compositional categories of carbonate rocks: grain composition, matrix composition, and cement composition, suggested that a carbonate rock classification should encompass aspects of all of these characteristics when trying to establish a rock name.
