Seeing all these rock identification questions, got me wondering, is there no straightforward guided rock identification website?
In Intro to Geology lab, I remember going through a bit of a process towards trying to identify different rocks. There are some pretty decent cloud sites/charts around these days, not just basic descriptions like here, here, and here, but great in-depth site like here, and and especially these step-by step guides like here and here.
I know there are a lot more types and complexity to rocks than clouds, and clouds typing tends to be a little less useful (in part because the formation mechanisms are fairly non-distinct). I've slowly started to see apps to lead you through plant/creature identification increasing, which is great, but are there any places we can point people to do the same for rocks?
