Embry has modified Dunham's classification and Klova

Two of the most widely used classifications are those of Folk (1959,1962) and Dunham (1962). Both classifications subdivide limestone s primarily on the basis of matrix content. Most limestone s are classified by Folk allochemical Rock s if they contain over l0% allochems (transported carbonate grains). Based on the percentage of interstitial ... Both are carbonate sedimentary rocks. Limestone is calcium carbonate. Dolomite is Calcium and Magnesium carbonate. To distinguish limestone from dolomite dilute hydrochloric acid is used. Limestone effervesces in the acid and only powdered dolomite effervesces in the acid. Below picture shows the transition of a limestone to dolomite. Crossplots of V p /V s ratio vs. compressional travel time, Δt c, facilitate identification of lithology trends with respect to porosity and lithology (Fig. 4). Recent studies of complex carbonate reservoirs indicate that the V p /V s ratio is a function of porosity and in some cases, can differentiate higher-permeability facies.Dolostone - In the Rock Classification Scheme, sedimentary rocks which are composed dominantly of dolomite or ankerite are given this group name. The textural classification of dolostones follows that for limestone. The classification of dolostones composed dominantly of one constituent similarly follows that for limestone.The limestone and dolomite that is commercially produced ranges in age from 323 - 393 million years old, to 497 - 541 million years old.
