Acasta Gneiss
The Acasta Gneiss is a Hadean tonalite gneiss that is the world's oldest surviving crustal rock.
It outcrops in the remotest Northwest Territories of the Canadian arctic and is only accessible
by sea-plane where temperatures are often almost -50 degrees celsius. As such it is expensive
to collect but worth it as no rock on earth is older. Dated to 4.03 billion years the specimens
listed here were all obtained directly from the legal owners of the mineral rights for the region.

Cambrian Beach
Sandstone
These slices are from the Mount Simon complex of Wisconsin and represent a beach deposit from
a series of barrier islands. The distinct banding in the specimens is clear to see with a very fine
grained layer alternating with a coarse sandstone, which is indicative of a storm event. Interesting
pieces preserving ancient storm activity from the late Cambrian. Thought provoking stuff.
