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.

I don't know about the wicklow rock, but your camera quality is unreal.
