molten magma

On the lava platform are also seen now and then considerable fissures which were caused by the abrupt cooling of the lava. Look at the rock under your foot. This light red colored rock is called granite which is derived from the crystallization of molten magma.

石龙上常常有宽大的裂缝，那是岩浆冷却后所致。你脚下的岩石，这种浅红色的岩石叫做花岗岩，它是由熔融的岩浆冷却结晶而形成。

Igneous rock is rock formed by solidification from a molten state; especially from molten magma.

火成岩是从熔融状态(特别是通过熔化岩浆)凝固而成的 石头.

At deeper levels, the volcanic deposits were intruded by molten magma, which slowly crystallised to form granite.

在地壳深处, 熔化的岩浆侵入原先形成的火山岩中, 慢慢结晶成为花岗岩.
