Hey there, I need a quick answer. I have to identify the five types of Plutons for a little project. Thing is the text book describes Plutons, but only give you examples of two, and I've googled and found more then just 5 names under plutons. I have; 1. Sills 2. Batholith 3. Dike 4. Veins I'm not sure as to the fifth. Is lava flow a pluton, or does old rock (ie hardened magma) count as a pluton? Thanks.
