What type of rock is this? ?

It's got areas that look like gold or fool's gold and areas that look like quartz, as well as some other layers. Thanks in advance.

    Definitely a lot of pyrite ("fool'S gold"; you can see a nice pyrite cube, even), but the picture is of lower resolution (has to be to post here, sadly) so hard to be sure about a lot of the details.  I suspect that there is also chalcopyrite in there, but I can't be sure.  I see nothing that makes me thing gold the substance (goldish color is not gold the mineral).  the white seems to be quartz but might be carbonate (I cannot see the crystal forms well enough to be certain), or even both.
