I have been watching ABC1 documentary about South Pacific Islands. Very interesting. The volcanoes, such large scale within Hawaii are just amazing. Now I have interests on rocks, the volcanic rocks.

Volcanic rock is an igneous rock of volcanic origin. Volcanic rocks are usually fine-grained or aphanitic to glassy in texture.

They often contain clasts of other rocks and phenocrysts. Phenocrysts are crystals that are larger than the matrix and are identifiable with the unaided eye. They were created during fractional crystallization of magma before extrusion.

I'm beginner on geology, and am going to decide what course I am going to study next year: maybe geology:) Would be interesting!

Would you have any recommendations? thanks
