Strolling down a New Zealand beach and I was amazed at the range of different types of rock. Obviously an area with volcanism, glaciers, sea, etc, so it makes sense there's some variety but can anyone tell me anything about this little selection?
I'm guessing the white is some kind of quartz but I've realised I know naff all about rocks. And what the hell is the really well defined triangle on the rock underneath?
