Characterizing cosmochemical materials with genetic affinities to the Earth: Genetic and chronological diversity within the IAB iron meteorite complex.

The IAB iron meteorite complicated consists of a principal group (MG) and 5 chemical subgroups (sLL, sLM, sLH, sHL, and sHH). Here, mass-independent Mo and radiogenic 182W isotope compositions are reported for IAB complicated meteorites to consider the genetics and chronology, respectively, of the MG and subgroups. Osmium isotopes are…
