Definition
Mudstone is a fine-grained, dark gray sedimentary rock, which is formed from silt and clay and is similar to shale but has less laminations
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite

Archaeological Significance
Formation
Mudstone forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are buried and compacted by overlying sediment hence forming mudstone.
Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.

All about Mudstone and Oolite Properties
Know all about Mudstone and Oolite properties here. All properties of rocks are important as they define the type of rock and its application. Mudstone and Oolite belong to Sedimentary Rocks.Texture of Mudstone is Clastic whereas that of Oolite is Clastic or Non-Clastic. Mudstone appears Rough and Dull and Oolite appears Rounded and Rough. The luster of Mudstone is dull while that of Oolite is pearly to shiny. Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors. The commercial uses of Mudstone are creating artwork, pottery and that of Oolite are creating artwork, jewelry, used in aquariums.
