Lava bantal: Perbedaan antara revisi

Lava bantal umumnya memiliki komposisi [[basal]]tik, meskipun bantal yang terbentuk dari [[komatit]], pikrit, [[boninit]], [[andesit]] basaltik, andesit, [[dasit]], atau bahkan [[riolit]] juga diketahui.<ref>{{cite web|url=http://web.wits.ac.za/NR/rdonlyres/47A7F879-4CC4-43ED-B69A-CC12ABDBDD8A/0/058_091_Chapter3.pdf |title=McCarthy, T. & Rubidge, B. 2008.
