Definition
Minette is a variety of Lamprophyre and is porphyritic alkaline igneous rock which is mainly dominated by biotite and potassic feldspar
Hyaloclastite is an aggregate of fine, glassy debris formed by the sudden contact of hot, coherent magma and cold water or water-saturated sediment

All about Minette and Hyaloclastite Properties
Know all about Minette and Hyaloclastite properties here. All properties of rocks are important as they define the type of rock and its application. Minette and Hyaloclastite belong to Igneous Rocks.Texture of Minette is Porphyritic whereas that of Hyaloclastite is Pyroclastic. Minette appears Dull, Banded and Foilated and Hyaloclastite appears Dull. The luster of Minette is subvitreous to dull while that of Hyaloclastite is dull and grainy. Minette is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Hyaloclastite is available in brown, grey, yellow colors. The commercial uses 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) and that of Hyaloclastite are cemetery markers, creating artwork.
