When snow experiences high pressures, it's forced to recrystallize and eventually compresses into ice - which is how glaciers form.

雪在高压下，会重结晶，并最终压成冰，冰川就是这样形成的。

All the minerals from the original rock recrystallize without having to melt down into molten rock.

原始岩石中的所有矿物质都会重新结晶， 而不必熔化成熔融岩石。

Or even re-melt and recrystallize to make new igneous rock.

甚至重新熔化并重结晶以制造 新的火成岩。
