Discover the oldest minerals on Earth with this extra-large Jack Hills metaconglomerate rock specimen from Erawondoo Hill, Western Australia. This unique geological treasure contains zircon crystals dated to approximately 4.4 Ga, making them the oldest known minerals on our planet.

Geological Significance

Located in the Narryer Gneiss Terrane of the Yilgarn Craton, the Jack Hills region features an 80 km long belt of folded and metamorphosed supracrustal rocks. The zircons from this location are extensively used for reliable U-Pb crystallization age dating, with some zircons dated at ~ 4.4Ga.

These ancient zircons also reveal fascinating insights into Earth’s history. Their oxygen isotopic composition suggests that more than 4.3 billion years ago, there may have been water on Earth’s surface!
