Gossan vs Hyaloclastite 

Definition

Definition

Gossan is intensely oxidized, weathered or decomposed rock, usually the upper and exposed part of an ore deposit or mineral vein.

Formation

Formation

Earth movements can cause rocks to be either deeply buried or squeezed and hence the rocks are heated and put under great pressure.
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
