These look to me like regular intrusive iron rich veins. Boulder is about 1m across, and sandstone/mudstone, area is volcanic.

I am not a geologist.. any ideas?

Brand new amateur collector here, I have a piece of a rock that im trying to identify that is covered in what seems to be iron, which is hiding this bright blue rock ive never seen before, however the rock is full of bubbles and is extremely jagged, is there a way to examine and polish without harming the shape
