Description

Upon study, Twannberg was classified as a IIG. This rare group has only six meteorites in its class. As stated in a study conducted by John T. Wasson, “The members of this group have low-Ni [Nickel] contents in the metal and large amounts of coarse schreibersite ((Fe,Ni)3P); their bulk P [Phosphorus] contents are 17–21 mg/g, the highest known in iron meteorites. Their S [Sulfur] contents are exceptionally low, ranging from 0.2 to 2 mg/g. We report neutron-activation-analysis data for metal samples; the data generally show smooth trends on element-Au [Gold] diagrams. The low Ir [Iridium] and high Au contents suggest formation during the late crystallization of a magma.”
