Strange rock

    Hiya guys

    Found this unusual rock a few miles up a mountain. It should out because it was sitting beside an old drain that might have been dug a few decades ago.

    There are a few very small bits of quartz, or what looks like quartz, in it.

    It's a piece of limestone. If limestone is not the native bedrock, then it may have been introduced as fill for the drain.

    No limestone in the area, I doubt it would have been added as there are some streams running close by and you could get plenty of stone out of the river.

    I just thought it was odd looking because off the numerous 'pointy' bits.

    Heres a rock I found in wicklow . Out part shows a square with what looks like a rusty square . There are more rust squares through the rock when it was broken open.
    Any ideas how the are formed.
