Hyaloclastite  and Hawaiite

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
Hawaiite is volcanic rock that resembles basalt. It is an olivine basalt with intermediate composition between alkali olivine and mugearite

5.1 Formation
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
Hawaiite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes and reach the Earth's surface.
