    Basalt + Opale... I think we need bigger/better pictures...
    Basalt

    Opal


    Growing up, i marveled at star-trek's science, and ignored the perfect society. Now, i try to ignore their science, and marvel at the society.

    Imagine, being able to create matter out of thin air, and not coming up with using drones for boarding hostile ships. Or using drones to defend your own ship. Heck, using drones to block energy attacks, counterattack or for surveillance. Unless, of course, they are nano-machines in your blood, which is a billion times more complex..

    I disagree with the identification of the first specimen as basalt. It looks much more like an or specimen from Butte Montana or one of the Copper areas in Colorado. I see pyrite and possible covellite/enargite/bornite in it.

    The second pair look like common opals to me too.

    If it helps, the rocks were found in Mexico. Not sure what area though.

    Ah, i had no idea you could click on the images for a larger view..

    With that in mind, i agree in seeing some fools gold on it, probably sulfur/iron deposits. Most definitely volcanic in origin.


    Above is bornite.. A copper, ferrous sulfide (ish) rock..

    With that i agree with Paleoichneum (what does that mean anyway)

    pyrit, much mor common than bornit would be chalkopyrit the yellow/golden parts of the stone are probably are mix out of more than those 3 minerals but I would guess that most parts are pyrit+chalkopyrit

    the host rock seems to me something intermediate to mafic, probably something out of a copperporphyry? would fit to the west of the mexican coast

    First one is some sort of common sulphide - probably pyrite or chalcopyrite - hosted in an intermediate to mafic mass, while the second looks like chert.
