Hermatite
By: Ian Nicklin
Hematite is a common ore of iron that was extensively mined in northern England in the 19th century. The miners referrred to globular aggregates of hematite, such as this, as "kidney-ore" since it reminded them of the organ. We call this shape "reniform," which means the same thing: kidney-shaped.
