Understanding the dynamics of our planet

Geosciences encompass the study of the four major parts on our planet: rocks, water, air and life. If you look closer at the various disciplines, you will see that geosciences cover a very broad field of applications.

How does our planet work? What is it made of and why we can live here? Can volcanic eruptions be predicted? How will human activities affect the future of our planet? What is the age of our planet? Geoscientists are able to answer these questions with a wide variety of Thermo Fisher Scientific products.

One of the ways to understand the chemical and physical evolution of the Earth, planets and other bodies of the solar system is by looking at the natural variations in isotope abundances of elements. Here we post the latest application developments and interesting scientific contributions related to our planet.

Geosciences highlights

Combining multiple ICP-MS systems for zircon petrology

ICP-MS combined with laser ablation is a powerful technique to get unique information on the age and formation of zircon minerals. This note describes how a single and multicollector ICP-MS were combined with a laser ablation system. This so-called “laser ablation split stream” technique enables simultaneous analysis of both U-Pb and Lu-Hf isotope ratios within one spot.


Geosciences topics

How was our planet formed and how did it evolve through time? What do we know about the formation of the solar system? What about the other planets around us? The natural variations in the relative abundances of isotopes of various elements can be used as tools to explain the mechanisms behind geological systems on Earth and in the cosmos. These provide insights into a variety of processes, like the evolution of the Earth surface, the evolution of the ocean chemistry and Earth climate, weathering processes on Earth, and many more.
