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

Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar

Formation

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

Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.
