Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite
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
Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.

All about Oolite and Hyaloclastite Properties
Know all about Oolite and Hyaloclastite properties here. All properties of rocks are important as they define the type of rock and its application. Oolite belongs to Sedimentary Rocks while Hyaloclastite belongs to Igneous Rocks.Texture of Oolite is Clastic or Non-Clastic whereas that of Hyaloclastite is Pyroclastic. Oolite appears Rounded and Rough and Hyaloclastite appears Dull. The luster of Oolite is pearly to shiny while that of Hyaloclastite is dull and grainy. Oolite and Hyaloclastite are available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors. The commercial uses of Oolite are creating artwork, jewelry, used in aquariums and that of Hyaloclastite are cemetery markers, creating artwork.
