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
Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture

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.
Latite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Mudstone and Latite Properties
Know all about Mudstone and Latite properties here. All properties of rocks are important as they define the type of rock and its application. Mudstone belongs to Sedimentary Rocks while Latite belongs to Igneous Rocks.Texture of Mudstone is Clastic whereas that of Latite is Aphanitic to Porphyritic. Mudstone appears Rough and Dull and Latite appears Rough. The luster of Mudstone is dull while that of Latite is subvitreous to dull. Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas Latite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Mudstone are creating artwork, pottery and that of Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo).
