'ONCOLITIC' IRONSTONE WITH MAGNETITE CRYSTALS
Hwange District, Matabeleland, Zimbabwe
A highly unusual ironstone with what appears to be oncolites enclosing rock fragments. It is packed with magnetite crystals. The magnet is included.
It is very attractive and is one of the most unusual rocks we have encountered.
This specimen is polished on one side and has a cut base so it stands up for display. From an old 1970s collection.
