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

答案在于同位素球化，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.

它涵盖了从球化到板块构造，再到岩石微观图像所有内容。

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.

是对球物理结构和物研究，而球化是化个分支，侧重于壳中岩石和矿物反应化成分。

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.

所以克拉克福克球化解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。

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

我倾向于这样初步理解：生命起源是从球化向生物化转变，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人潜水器，对海洋、球物理、球化、海洋环境、海洋生物等研究作出了巨大贡献。

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

我需要与位比我想象更了解球化人交谈。
