Also, it is suggested that at least 20 % of Mg is lost from continents by chemical weathering (Mg being extremely mobile during weathering), which is one of the primary controls for finally leaving behind a Si - rich and Mg - poor continental mass, thereby decreasing crustal recycling by subduction (Lee et al. 2008), important for continental survival.

According to this theory for lunar formation, a rock type called ferroan anorthosite, or FAN, is the oldest of the Moon's crustal rocks, but scientists have had difficulty dating FAN samples.

«Overall, this new image of Yellowstone's crustal magma reservoir provides a better understanding of the magmatic volume, melt configuration, and fluid state that control its potential for future volcanism and its joint volcano ‐ earthquake hazard, as well as a basis for assessing temporal changes in the reservoir properties that could portend new volcanism,» the researchers wrote in their study.

Convective patterns driven by heat transport in the interior of the Earth push one crustal plate under another (subduction) and the friction heats up the magma necessary for volcanic action — which in turn releases CO2 into the atmosphere.
