The 40Ar/39Ar technique is an important method in Earth and Planetary sciences which allow precisely dating rocks… Wanna know how it works?

This is the technique I truly built my career on. What I learned right away is that a precise and more importantly, an accurate age for a rock is critical to understand the story it tells and the 40Ar/39Ar technique can do both with a permil precision (e.g. 4531 ± 6 Ma eruption on Vesta or 14.81 ±0.02 for the Ries Crater). In this paper, we explain what this technique is all about and we provide a set of best-practice guidelines when reporting and interpreting 40Ar/39Ar data. This paper was published earlier this year in GSA bulletin with a vast list of co-authors involving a large part of the Ar community. A few co-authors on Linkedin: Allen Schaen, Kip Hodges, David Phillips, Leah Morgan, Simon Kelley, Elizabeth Niespolo, Klaudia Kuiper, Laura Webb, Jan Wijbrans, Huaning QIU and Brad Singer. Full list in the paper.

NOTE: such paper allows standardizing a technique across the board and allow for a FAIR reporting of the data. If you are not familiar, FAIR data are data which meet principles of findability, accessibility, interoperability, and reusability check it here (https://en.wikipedia.org/wiki/FAIR_data) as it’s going to become increasingly important for people to publish their data under the FAIR guideline.
