Definition
Lamprophyre is uncommon igneous rocks primarily occurring as dikes, lopoliths, laccoliths, stocks and small intrusions
Hyaloclastite is an aggregate of fine, glassy debris formed by the sudden contact of hot, coherent magma and cold water or water-saturated sediment

Formation
Lamprophyre formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.

All about Lamprophyre and Hyaloclastite Properties
Know all about Lamprophyre and Hyaloclastite properties here. All properties of rocks are important as they define the type of rock and its application. Lamprophyre and Hyaloclastite belong to Igneous Rocks.Texture of Lamprophyre is Porphyritic whereas that of Hyaloclastite is Pyroclastic. Lamprophyre appears Dull, Banded and Foilated and Hyaloclastite appears Dull. The luster of Lamprophyre is subvitreous to dull while that of Hyaloclastite is dull and grainy. Lamprophyre 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 Lamprophyre 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.
