Minette and Mudstone


Definition

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   
Minette is a variety of Lamprophyre and is porphyritic alkaline igneous rock which is mainly dominated by biotite and potassic feldspar

Formation

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.   
Minette formation takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.

All about Mudstone and Minette Properties

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