This extra-large Jack Hills metaconglomerate rock specimen is from the Erawondoo Hill location in Western Australia. This metaconglomerate contains the oldest minerals on Earth - Zircon crystals dated to ~ 4.4 Ga. Zircons found at this location and are currently Earth's oldest zircon minerals on Earth.

The Jack Hills are located in the Narryer Gneiss Terrane of the Yilgarn Craton, Western Australia, and comprise an 80 km long northeast-trending belt of folded and metamorphosed supracrustal rocks. The dating of zircons from this location continues to be extensively used to provide reliable U-Pb crystallization ages. Zircon minerals of 4,404 +/- 8 Ma are a reliable date for this material.

Zircons also show another exciting feature. Their oxygen isotopic composition has been interpreted to indicate that more than 4.3 billion years ago, there may have been water on the surface of the Earth.

Rough Rock Specimen size: 233mm L X 238mm W X 49mm D; Weight: 4.04956 kg or 8.9278 lbs or about 4,050 grams.
