A batholith is a geological formation created when a vast quantity of molten rock rises through a planet's crust, spreading out sideways as it does so.

岩基是一种地质构造，熔融岩石在穿过行星地壳时横向扩散形成。

The rocks of Yosemite, for example, are parts of the Sierra Nevada batholith, uncovered and spectacularly sculpted by subsequent erosion.

例如， 优胜美地的岩石是内华山脉岩基的一部分，后来被侵蚀作用揭露并壮观地雕琢而成。

The batholith, which has been discovered below Compton-Belkovich, a volcanic-looking set of features on the far side of the moon, hardly promises that.

在康普顿-贝奇（Compton-Belkovich）下方发现的浴石，这是月球背面的一组火山状特征，很难保证这一点。

The Compton-Belkovich batholith is also made of granite, which is what gave it away.

康普顿-贝奇岩基也是花岗岩构成的，这暴露了它的身份。

On Earth, these batholiths are composed mostly of granite.

在地球上，这些岩基主要花岗岩构成。
