Definition

A ganister is a hard, fine-grained quartzose sandstone or orthoquartzite which is basically used in the manufacture of silica brick typically used to line furnaces and is a type of sedimentary rocks.

Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities

Formation

Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.

Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
