摘要：

Epidote is stable only at high pressure in granitic magmas but is found in magmas crystallized at shallow crustal levels. This observation suggests qualitatively that magma transport is sufficiently rapid to prevent complete epidote resorption. Experimental measurements of epidote dissolution showed that the presence of epidote implies that magma transport from the deep crust in these systems was rapid and that the transport was by dikes rather than diapirs.
