This rock has a light, pinkish color (that tells you the composition) and mostly invisible crystals (that tells you whether the rock cooled from magma or lava). Still, you can notice some scattered, visible black crystals. It looks like there are two crystal sizes in this rock! What is its name? vesicular basalt pegmatitic granite phaneritic peridotite porphyritic rhyolite aphanitic andesite This rock, from the previous question, where would it be more likely to form? at a mid-ocean ridge at the core of a pluton at a volcanic vent close to a shallow source of heat on continental crust at a transform fault all of these
