Hawaii's Kilauea volcano just produced its most spectacular lava fountains in decades, sending molten rock in a wide arc more than 1,000 feet into the air. This occurred alongside a 14,000 foot high eruption plume which was easily seen from the summit of Mauna Kea. Today's video will discuss Sunday's eruption which created scenes that almost look fake due to how unusual they were.

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
