Archaeological Significance
Formation
Alkali fledspar granite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
