Dunham classification Wikipedia

Robert J. Dunham published his classification system for limestone in 1962. The original Dunham classification system was developed in order to provide convenient depositional-texture based class names that focus attention on the textural properties that are most significant for interpreting the depositional environment of the rocks. The three criteria used to define the original Dunham classes were:

Dunham classification Encyclopedia

Dunham classification A widely used limestone classification, proposed by Robert Dunham in 1962, which divides limestones on the basis of their texture and mud content. For limestones which retain their original, depositional texture, the main subdivisions are: lime mudstone (limestone with less than 10% grains in a mud-supported sediment); lime wackestone (limestone with more than 10% grains

Dunham classification WikiMili, The Free Encyclopedia

The Dunham classification system for carbonate sedimentary rocks was originally devised by Robert J. Dunham in 1962, [1] and subsequently modified by Embry and Klovan in 1971 [2] to include coarse-grained limestones and sediments that had been organically bound at the time of deposition.

Carbonate Classification SEPM Strata

May 10, 2013 Embry has modified Dunham's classification and Klovan (1971) to include coarse grained carbonates (above figure). In their revised scheme, a wackestone in which the grains are greater than 2mm in size is termed a floatstone and a coarse grainstone is called a rudstone.

Carbonate classification AAPG Wiki

Figure 1 Folk and Dunham classifications. The two commonest classification systems for carbonate rocks are those of Folk [1] and Dunham. [2] Folk's classification uses combination forms of words describing the grains and words describing the cements.

Carbonates & Other Rocks

Dunham Classification. The Dunham classification is based on the concept of grain support. The classification divides carbonate rocks into two broad groups, those whose original components were not bound together during deposition and those whose original components formed in place and consist of intergrowths of skeletal material.

Introduction to Carbonate Facies, Depositional

DUNHAM’S CARBONATE ROCK TEXTURE CLASSIFICATION. Dunham (1962) produced a classification of carbonate rocks that is based on depositional texture. He noted that there are several textural features that are especially useful in classifying carbonate rocks: (1) presence or absence of carbonate mud (particles less than 20 microns),

Carbonate Sedimentary Rock Classification

Oct 26, 2000 Two carbonate classification systems are in common use today, one by R.L. Folk and the second by R.J. Dunham . The Dunham system is based on depositional texture (that is, the amount of matrix surrounding the grains at the time of deposition). It uses such names as mudstone, wackestone, packstone, grainstone, and boundstone.

May 11, 2016 The Dunham classification system was proved to be the scheme of choice with 89% of the classifications using some form of the Dunham system. However, all of the 24 samples yielded a wide variability in assigned texture with between 22 and 131 different names being assigned to a single specimen. The most common causes of inconsistency are

Carbonate Classification GeoMika

Jul 27, 2013 Compare and contrast the carbonate classification schemes of Folk and Dunham. Carbonate rocks are composed of allochems and orthochems. Allochems are the outside components, effectively grains that are the equivalent of clasts in sandstones. Orthochems are the inside components, the microcrystalline binding materials of matrix or cement. Common carbonate classification

Aug 17, 2014 The Dunham classification is similar to that of clastic rocks, in that it clearly shows the role of energy in sediment accumulation. The main distinction between rock types is based upon the relative abundance of allochems (framework grains) and matrix. Cement is treated as open pore space. Dunham Classification 5.
