The best rock cycle diagram I have ever seen!

I’ve gotta admit, as geeky as this sounds, I’m pretty excited over this rock cycle diagram I found at www.geologycafe.com.  I wish I had this available while I was in college, because it not only shows the different processes in the rock cycle (i.e. deposition), but it also shows the types of rocks (igneous, metamorphic and sedimentary) that are formed in the different geologic settings (volcanism, plutonism, tectonism).  For example, in the case of metamorphic rocks, it illustrates that with heat and pressure the rocks transform to gneiss and schist.  Unless, I’m missing it, I don’t see phyllite, though which would have been helpful.  It also shows the different types of conformities, as well as faulting types and numerous geologic terms. So, if you are a student in geology, I highly recommend reviewing this rock cycle diagram.  It will give you a better understanding than the traditional rock cycle diagrams of old.

    Thanks for your websites and comments about the “rock cycle” diagram…

    I drew that diagram while I was recovering from a stem-cell implant, and was on a drug called Mirapex… They told me not to gamble while I was on the drug, so I drew this diagram.

    Why there is no “Phyllite” on Phil’s diagram… hmmm…. I wasn’t thinking about myself at the time.

    Thanks for honoring me…!

    Sincerely, “Fossil” Phil

    P.S. Check out: http://gotbooks.miracosta.edu – I just finished preliminary versions of free textbooks in oceanography and geology. Having seen how much textbooks cost, I released all my information free on the web… Why should students pay more for a textbook than the tuition to play for the class? Cheers! Phil

      Haha! Good to hear from you, Fossil Phil. I just referred a student to your free books – that’s awesome that you provide them. I have a random plug in that repeats old posts, and this post always gets a lot of attention. It’s still one of my favorite diagrams for undergrad students. 🙂 Do you want to do a guest blog series and tell us all about your work and websites? If so, contact me at sandie@sandiewill.com.
