Lots of Crystals vs Not So Much

Caption

Magmas with more than 20 percent crystals tend to form connected networks that channel the gas. The image on the right shows magma that is 33.1 percent crystals. The crystals are channeling the gas bubbles, shown in green and blue. The image to the left does not contain enough crystals to channel the gas.
