Definition
Hyaloclastite is an aggregate of fine, glassy debris formed by the sudden contact of hot, coherent magma and cold water or water-saturated sediment
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

Formation
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
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 Hyaloclastite and Mudstone Properties
Know all about Hyaloclastite and Mudstone properties here. All properties of rocks are important as they define the type of rock and its application. Hyaloclastite belongs to Igneous Rocks while Mudstone belongs to Sedimentary Rocks.Texture of Hyaloclastite is Pyroclastic whereas that of Mudstone is Clastic. Hyaloclastite appears Dull and Mudstone appears Rough and Dull. The luster of Hyaloclastite is dull and grainy while that of Mudstone is dull. Hyaloclastite is available in brown, grey, yellow colors whereas Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. The commercial uses of Hyaloclastite are cemetery markers, creating artwork and that of Mudstone are creating artwork, pottery.
