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

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.
