Mount Dooling - Iron, IC

Mount Dooling is a rare IC Iron meteorite from Western Australia, first found in 1909 near Lake Giles, around 8 km east of Mount Dooling. Additional related masses and synonyms, including Gosnells and Lake Giles, have been linked to the same meteorite in later studies. With a recorded total known weight of around 734 kg, Mount Dooling is one of the more important Australian Iron meteorites and a recognised member of the small IC chemical group.

Mount Dooling is composed primarily of iron-nickel metal and is structurally described as an Octahedrite, though its Widmanstätten pattern can be poorly defined due to the near absence of taenite and plessite. Specimens may show dense metallic character, weathered surfaces, and internal structure when cut, polished, and etched. The IC group is relatively small, with Mount Dooling often listed alongside other representative IC Irons such as Bendegó and Arispe.

Studying Mount Dooling provides insight into the formation and cooling of rare IC Iron meteorites, as well as the diversity of metallic asteroid material in the early solar system. Its Western Australian provenance, historic discovery, unusual structure, and scarce classification make it especially appealing for collectors of Iron meteorites and Australian finds. Each specimen represents ancient asteroid core material preserved in metallic form for over 4.5 billion years.
