Formation

Formation

Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
Trachyte is an igneous volcanic rock with an aphanitic to porphyritic texture. It is the volcanic equivalent of syenite rock and forms as a result of magmatic differentiation.
