Hyaloclastite  and Porphyry

1 Definition
1.1 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
Porphyry is a reddish-brown to purple igneous rock containing large phenocrysts of various minerals embedded in a fine-grained matrix

5 Formation
5.1 Formation
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
Porphyry is formed in two stages: the magma cools slowly deep within the crust or the magma is cools rapidly as it erupts from a volcano, creating small grains that are usually invisible to naked eye.
