It's difficult too say what these rocks are, but I suspect they are not sedimentary but more igneous or metamorphic. The last one could however be a coarse grained clastic, that has been undergoing high levels of diagenisis in my oppinion. My first guess would be an extrusive igneous rock as I small crystals.. make some pictures of the texture and grains for a better clasification.. |
