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

Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone

Formation

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

Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
