adj.变质的

The rocks in this area are predominantly metamorphic, having been transformed by heat and pressure over millions of years.
这个地区的岩石主要是变质岩，经过数百万年的热力和压力作用而形成。
Metamorphic rock is formed when pre-existing rocks are changed by high temperature, high pressure, or hot, mineral-rich fluids, often deep below the Earth's surface.
变质岩是在高温、高压或富含矿物质的热水的作用下，将原有的岩石在地球深处改变而成。
The marble we see today was once limestone that underwent metamorphism due to intense heat and pressure.
我们今天看到的大理石，曾经是石灰石，在强烈的热力和压力作用下发生了变质。
Geologists study the texture and mineralogy of metamorphic rocks to understand the conditions under which they were formed.
地质学家研究变质岩的结构和矿物学特征，以了解它们形成时的条件。
The foliation in metamorphic rocks indicates the direction of the applied pressure during their formation.
变质岩中的片理表明了在它们形成过程中所受压力的方向。
Metamorphic grade refers to the intensity of the conditions (temperature and pressure) under which metamorphism occurs.
变质级别指的是变质作用发生的条件（温度和压力）的强度。
Some metamorphic rocks, such as gneiss, can be very attractive and are used in construction and decoration.
一些变质岩，如片麻岩，非常美观，被用于建筑和装饰。
The presence of certain minerals in metamorphic rocks can indicate the specific type of metamorphism they have undergone.
变质岩中某些矿物质的存在可以指示它们经历的具体变质类型。
Metamorphic events often result in the recrystallization of minerals within rocks, altering their physical properties.
变质事件通常导致岩石内部矿物质的重新结晶，改变其物理性质。
Understanding the metamorphic history of a region can provide insights into the geological processes that have shaped it.
理解一个区域的变质历史可以提供对塑造它的地质过程的深入了解。
