Iron meteorite, anomalous hexahedrite (IIG)
Find 1867, 43 kg
Six separate masses of Fe-Ni metal (Ni ~ 4-5%) were found in Choctaw and Sumter counties from 1859-1886 (a line 16 km long). Fragments weighed between 0.757 and 11.976 kg. A kamacite matrix accompanied by schreibersite ribbons is quite common, but the separate masses — often heavily weathered — are not entirely homogeneous. A few troilite nodules are sometimes embedded in the much more abundant schreibersite. While the predominant structure is that of a hexahedrite, minor amounts of taenite and plessite are also present. While in space Tombigbee River experienced both severe shock and some uneven annealing. Once on earth at least one of the recovered pieces has been exposed to artificial heating.
Tombigbee River was the first to be recovered and remains the most massive of the small IIG iron meteorite group with only six known members.
