This is a type of volcanic landscape. There are two stages in the formation of a common caldera; the first is the volcanic eruption, and the second is the formation of a large crater with subsidence. If a caldera becomes active again after its formation, the erupted material is usually in the form of spraying lava or, when intruding, in the form of a rock dome. Eventually, the intruded magma forms intrusive rock bodies in the central part of the caldera. This type of caldera, which has experienced subsidence and then another eruption, is called a resurgent caldera. The Valles Caldera in New Mexico, the USA, is a typical example. Yandangshan in Zhejiang Province is a resurgent caldera that formed approximately 100 million years ago.
