A Wackestone in thin section (width of image is 10 mm) Under the Dunham classification (Dunham, 1962 [1]) system of limestones, a wackestone is defined as a mud-supported carbonate rock that contains greater than 10% grains.

Wackestone: Mud-supported carbonate rock containing more than 10 percent grains (Dunham, 1962). Generally indicates calm water and restriction of grain-producing organisms (low-energy depositional setting).

Thin section photomicrograph of a fragmented bioclast wackestone in plane polarised light. On the basis of these criteria, the following four classes were defined: a mud-supported carbonate rock containing <10% grains. a mud-supported carbonate lithology containing >10% grains. a grain-supported fabric containing 1% or more mud-grade fraction.

If the sediment is mud supported but contains more than 10 percent grains, then it is known as a wackestone, and if it contains less than 10 percent grains and is mud supported, it is known as a mudstone.

Dec 19, 2023 · Wackestone: a mud-supported rock with > 10% grains, and original components are not organically bounded together during deposition (Figure 14). Packstone: a grain-supported rock with lime mud presented, and original components are not organically bounded together during deposition (Figure 15).

Feb 25, 2025 · Wacke, or graywacke, is the name applied to generally dark-coloured, very strongly bonded sandstones that consist of a heterogeneous mixture of rock fragments, feldspar, and quartz of sand size, together with appreciable amounts of mud matrix. Almost all wackes originated in the sea, and many were deposited in deep water by turbidity currents.

A matrix-supported biochemical/chemical rock containing less than 75% mud-grade (< 32μm) material (usually carbonate) Please feel free to link to this page.

Wackestone is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles settle down and are then compacted due to high …

Under the Dunham classification (Dunham, 1962) system of limestones, a wackestone is defined as a mud-supported carbonate rock that contains greater than 10% grains. Most recently, this definition has been clarified as a carbonate-dominated rock …

Wackestone is a matrix-supported carbonate rock that contains over 10% allochems in a carbonate mud matrix. This is part of the Dunham classification of carbonate rocks.
