Over time it will slowly cool and some minerals will crystallize out of the magma and fall to the bottom of the chamber, leaving a residual pool of magma on the top. Most of Earths history (from the formation of the earth 4.6 billion years ago to approximately 541 million years ago) is known as the Precambrian time. Over long periods of time, magma chambers can crystallize into large intrusive igneous rock formations called batholiths. Fumarole. Also known as a magma storage zone or magma reservoir . Magma also rises when these tectonic plates move toward each other. We imagine that the magma chamber beneath a volcano is a cavity full of magma. A _______ volcano is a wide gently sloping mountain formed by thin layers of lava pouring out of the vent and hardening on other layers. Magma rises through cracks from beneath and across the crust because it is less dense than the surrounding rock. Vivid colors fill Thrihnukagigur's magma chamber.
