TIGER IRON SLAB. ...

Description

TIGER IRON SLAB
Paleoproterozoic
Western Australia
This beautiful slab of tiger iron is an excellent example of the distinctive banding formed by folded layers of flashing golden Tiger's - eye, red jasper, hematite (iron oxide) and stromatolite. This last constituent represents the oldest organism in the fossil record, the 2½ billion year old remains of cyanobacteria or algae. The gentle curves and waves of the layers bear witness to the immense pressures to which the rock is inexorably subjected over an almost unimaginable amount of time. This beautiful and highly polished diamond-shaped slab is an excellent example of the distinctive banding and measures 33 3/8 x 20¼ x ½ inches.
