Latite and Mudstone
Definition
Definition
Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture
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 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.
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.

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