Group IAB, currently with 264 members, is the second largest iron-meteorite group and the largest non-magmatic iron group. Many of its members contain silicates and all have been modeled to have crystallized from impact melt pools on chondrite parent bodies. The UCLA team, under the direction of John Wasson, analyzed more than 220 IAB irons over five decades using neutron activation analysis. Most of the data were published in six journal papers. The UCLA team works with AstroMat to make these data available online in the form of both downloadable datasheets and interactive tables. Group IAB is part of an ongoing effort to archive the UCLA iron meteorite data. Data for other iron meteorite groups will be made available on AstroMat in the coming months.

Data for IAB Group meteorites now available in the Astromaterials Data Repository

AstroSearch 2.0 beta is now online. You can now refine your queries by analysis type and variable range. Your feedback will help us refine v 2.0 until it is ready to replace the current AstroDB Search.

AstroSearch 2.0 beta

AstroMat staff will be presenting their poster, “Bringing Lab Analytical Data for Astromaterials to the Planetary Data Ecosystem” at the upcoming 2nd Planetary Science Informatics & Data Analytics Meeting. Catch the preview on Wednesday, June 30, 2021 at 1PM EDT during the poster session. See the entire program here.

Data Availability Update

Dear Astromaterials Data System mailing list subscribers,

Thanks to all who joined us at the Astromat Workshop at MetSoc24! We had a great discussion about data archiving needs in the astromaterials community and standards for astromaterials sample data.

We recently updated the Astromat website with an improved site layout, live system statistics, and quicker ways to get to the information and data you need. Take a look and let us know if you have any feedback or suggestions.

Members of the Astromat Team will be at Goldschmidt 2024 in Chicago next week. Come find us at the Exhibit Hall or one of the following sessions!

Exhibit Hall: EarthChem & the Astromaterials Data System Booth #2

Select OSIRIS-REx Sample Data Now Available in Astromaterials Data Archive

Data from the initial analyses of asteroid Bennu by the OSIRIS-REx Sample Analysis Team are now available in the Astromaterials Data Archive (ADA). Approximately 100 datasets are now accessible to download out of the ~500 datasets received to date. As future OREx publications are released, the associated datasets in ADA will be made publicly accessible.

Our team is planning a series of webinars starting Fall 2024 on archiving your data and accessing data through Astromat. Stay tuned here for the dates and registration information. If you have suggestions or would more information on using Astromat services, please feel free to reach out to our team!
