We have Jack Hills zircon metaconglomerate from Erawondoo Hill in Western Australia for sale. This location has zircon rocks, the oldest minerals on Earth, with an age of 4.35 Ga. Formed during the Cryptic era, Hadean eon, these zircon-bearing rocks from this location are unquestionably the most sought-after specimens for geological collections.

Zircons not only have long memories but share them readily, as well. The age of Earth's oldest known rocks is Acasta Gneiss of Northwestern Canada. However, the most ancient minerals found on Earth are the tiny zircon crystals that have survived as small grains in the ancient sandstone discovered in the Jack Hills, Erawondoo Hill location of Western Australia.

The robustness of zircon crystals can be seen in their incredible ability to withstand aggressive deformation events. A zircon crystal can lie dormant for eons and grow new concentric layers when intermittently reheated in magmatic or tectonic events. This layering is analogous to the growth of tree rings, as this layering can be observed in growth spurts separated by hundreds of millions of years in geologic time. Earth's tectonic history, or even that of a continent, can be traced in a single zircon crystal grain.
