Tiger Iron.
Tiger iron comes from the Ord Ranges near Port Hedland in Western Australia's Pilbara region . .
Tiger iron is a banded iron formation (BIF) or jaspilite that has alternating layers of black & brown hematite/magnetite, red jasper & chatoyant golden tiger eye.
The
best material is that which has been subject to faulting &/or folding.
It displays all of those amazing zig zags & swirls that are so
desirable.
The deposit only covers a small area in a harsh,
rocky range of low hills that supports almost no vegetation other than the
spiky spinifex grass.
As the area is almost all rock, it takes a
big machine to get the stuff out. This is a 95 ton bulldozer that I used
in 1992 to try a locate another deposit. It was all in vain. I still have
to buy my tiger iron from the original source, which is controlled by
someone else.
