Interobject Structure of Ungrouped Iron Meteorites as Revealed by Advanced Clustering: Methods and Chemical Features

Abstract

Using the MASLOC clustering strategy, 61 ungrouped iron meteorites are probed for physico‐chemical clusters. The existing classification of 13 resolved chemical groups is used as an internal coherence reference. Results include tentative establishment of a new group: ID (7 members), with chemical features similar to those of the non‐magnetic groups IAB and IIICD. Six additional pairings, all with magmatic chemical signatures, are also recognized.
