Back to Basics
Discussing the nitty gritty of Re-Os-Hg analysis

Re-Os Isochrons
It may be the final days of October, but holding to our desired schedule and talking isochrons today.
So exactly how do you analyze samples with daughter 187Os present at the time of crystallization or formation?
Let's find out!

Age Equation and Model Ages
As promised, we are back to the blog and discussing the theory behind the age equation and how we calculate an example molybdenite model age.
Let's jump in!

Ah! It's Been A Year!
Fear not! The lack up blog posts and major website updates only means AIRIE is busily producing the accurate and informative Re-Os geochronology you need. Yet we also know these blogs are helpful, informative, and hopefully engaging; so we'll be producing six new posts over the next six months.
In the meantime, see what we've been up to over the last year.

Isotope Dilution
Before introducing the age equation and how AIRIE determines geological ages, we first must explain how to determine the sample's rhenium and osmium concentration (and associated parent 187Re and daughter 187Os).
Introducing Isotope Dilution -- the Key to the Kingdom.

Elements, Isotopes, and Radioactive Decay
To kick off the AIRIE Blog series, it is back to basics with a refresher on elements, isotopes, and radioactive decay. With a solid understanding of these topics, we will be able to dig deep into rhenium-osmium (Re-Os) analysis and the nitty gritty details on how AIRIE produces geochronological data.
Rhenium and osmium are two of (roughly) 91 naturally occurring elements found naturally in nature. Read more...

Coming Soon...
AIRIE, always rising! Re-Os-Hg data proves invaluable when investigating ore-forming systems, petroleum systems, mass extinctions and climate change, sea water chemistry, crustal fluid mobility, metals in soil, and timing of geological events.
After 25 years at Colorado State University, AIRIE is up and running as a small, engaging, and efficient small business still producing the Re-Os-Hg data for which we are known. We are now located at the Innosphere Ventures technology incubator campus in north Fort Collins. Come work with the team that pioneered Re-Os applications in crustal rocks for resource geology and extended the system beyond what the founders thought possible.
In the following weeks, we will update the blog with deep dives into Re-Os-Hg geochemistry and analysis. Background theory, historical perspectives, and unique applications will be presented in quick-read blog posts.
Additionally, application specific posts will aid in understanding AIRIE results, complement our reports, and provide background on how the data was produced.
Stay tuned.
