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
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite

Formation
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
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.

More about Hyaloclastite and Oolite
Here you can know more about Hyaloclastite and Oolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hyaloclastite and Oolite consists of mineral content and compound content. The mineral content of Hyaloclastite includes Calcite, Chlorite and mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Igneous Rocks. When we have to compare Hyaloclastite vs Oolite, the texture, color and appearance plays an important role in determining the type of rock. Hyaloclastite is available in brown, grey, yellow colors whereas, Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors. Appearance of Hyaloclastite is Dull and that of Oolite is Rounded and Rough. Properties of rock is another aspect for Hyaloclastite vs Oolite. The hardness of Hyaloclastite is 1-2 and that of Oolite is 3-4. The types of Hyaloclastite are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff and Andesitic tuff. whereas types of Oolite are Not Available.
