1.1 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

Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction

5 Formation

5.1 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.

Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

All about Mudstone and Boninite Properties

Know all about Mudstone and Boninite properties here. All properties of rocks are important as they define the type of rock and its application. Mudstone belongs to Sedimentary Rocks while Boninite belongs to Igneous Rocks.Texture of Mudstone is Clastic whereas that of Boninite is Aphanitic to Porphyritic. Mudstone appears Rough and Dull and Boninite appears Dull and Soft. The luster of Mudstone is dull while that of Boninite is vitreous. Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas Boninite is available in bluish - grey, brown, colourless, green, grey colors. The commercial uses of Mudstone are creating artwork, pottery and that of Boninite are an oil and gas reservoir, cemetery markers, creating artwork, soil conditioner, source of magnesia (mgo).
