The answer lies in a slightly obscure but ingenious field known as isotope geochemistry.

在于同位素化学，这是个不大知名而又十分奇妙的领域。

It covered everything from the geochemistry to plate tectonics, to microscopic images of its rocks.

它涵盖了从化学到板块构造，再到岩石的微观图像的所有内容。

His definition of " geochemistry" stretches, however, well beyond many people's, into political and economic history.

然而，他对“化学”的定义远远超了很多人的定义，延伸到了政治和经济上。

I need to talk to somebody who knows more about geochemistry than I do I think for that one.

我需要与一位比我想象的更了解化学的人交谈。

It is the world's deepest working submersible, greatly contributing to the study of marine geology, geophysics, geochemistry, the marine environment, and marine biology.

这是全工作深度最深的载人潜水器，对海洋、物理、化学、海洋环境、海洋生物等研究作了巨大贡献。

So the Clark Fork geochemistry explains why acid rain isn't as devastating here as it is in, say, the Adirondack Mountains of New York where there is no limestone.

因此，克拉克福克化学解释了为什么酸雨在这里不像在没有石灰岩的纽约阿迪朗达克山脉那样具有破坏性。

Geology is the study of the Earth's physical structure and substance, while geochemistry is a branch of chemistry that focuses on the chemical composition of reactions in rocks and minerals in the Earth's crust.

学是对物理结构和物的研究，而化学是化学的一个分支，侧重于壳中岩石和矿物反应的化学成分。
