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

答案在于同位素地球化学，这是个不大知名而又十分奇妙领域。

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

它涵盖了从地球化学到板块构造，再到岩石微观图像所有内容。

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

需要与一位象更了地球化学谈。

I tend to think of it, initially, the origin  of life is a transition from geochemistry to biochemistry, which it must have been.

倾向于这样初步理：生命起源是从地球化学向生物化学转变，这必然是事实。

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

这是全球工作深度最深载潜水器，对海洋地质、地球物理、地球化学、海洋环境、海洋生物等研究作出了巨大贡献。

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.

所以克拉克福克地球化学释了为什么这里酸雨不像纽约阿迪朗达克山脉那样具有毁灭性，因为那里没有石灰石。

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.

地质学是对地球物理结构和物质研究，而地球化学是化学一个分支，侧重于地壳中岩石和矿物反应化学成分。
