Liesegang banding in jointed, deformation-banded sandstone, Sheets Gulch, Circle Cliffs uplift, Utah.


I collected this, as already emphasized, in Sheets Gulch, back in the late 1990’s.  It is a bizarre piece, which I really like.  Most people who see this might not even think of it as a rock, more likely some old part from a wrecked car, …a part collected in a junk yard.

Age & Formation
Navajo Sandstone of Jurassic age, ~170 Ma, laced with deformation bands that formed in latest Cretaceous to Eocene, i.e., ~70-55Ma.
