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
Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas

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.
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

All about Mudstone and Laterite Properties
Know all about Mudstone and Laterite properties here. All properties of rocks are important as they define the type of rock and its application. Mudstone and Laterite belong to Sedimentary Rocks.Texture of Mudstone is Clastic whereas that of Laterite is Earthy, Massive, Porphyritic. Mudstone appears Rough and Dull and Laterite appears Rough and Banded. The luster of Mudstone and Laterite is dull. Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas Laterite is available in brown, buff, red colors. The commercial uses of Mudstone are creating artwork, pottery and that of Laterite are an oil and gas reservoir, source of bauxite, used in aquariums.
