Changes in the new UPb DRS (“U_Pb_Geochronology3”)

There are some noteworthy improvements in the latest release of the UPb DRS (U_Pb_Geochronology3), so I thought I should post a description of what’s changed. One of the biggest changes is that flexibility has been added in which isotopes have been measured – previous versions required 206, 207, 208, 232, and 238 (with an option…

Iolite Wiki gets a facelift

The Iolite Wiki (http://iolite.earthsci.unimelb.edu.au/wiki/doku) has a shiny new theme, and is now more readable. We’ve updated parts of the online manual, which we recommend is your first port of call if you’re new to Iolite. You can also find example data files and more information on the Trace_Element_IS and U-Pb geochronology DRS. If you have…

Iolite Community Development

*** Updated with interference goodness! *** Seeing as it’s been a while since we last posted to the blog, we thought it’d be a good idea to point out that the Iolite team aren’t the only ones working on Iolite. There are others who are improving Iolite by adding their own features to make their…

CellSpace images tutorial

The Iolite team and Ash Norris from Resonetics have been working on a new way of creating images. We take the spatial information recorded in laser log files and combine that with mass spec data to produce images of composition versus sampling position in the laser cell. This has some great advantages:-images don’t need to…

Programming Basics for Iolite

We’re getting a lot of users that want to customise the way Iolite processes their data, which is really exciting as it’s exactly why we built Iolite in the way that we did. But we realise that there may be many more that just find getting into the programming code a little too intimidating, or…

How to add more globals to a DRS

This is just a quick tutorial to show you how to add more global variables or global strings to a DRS. These globals are useful because they’re acessible via the Edit Settings window, which means that people not comfortable with the code can quickly and easily view and modify them (e.g., the “ReferenceStandard” global string).…

Uncertainty propagation – how it works

We’ve had a bit of interest in propagation of uncertainties in Iolite, so I thought I’d try to do two things in this post and the next. In this post, I’ll have a go at describing our protocol for propagating uncertainties. There is a description of the method in Paton et al. (2010), but I’ll…
