Jack Hills Zircon Sand in Microslide
Zircon minerals of 4,404 +/- 8 Ma have been obtained from a sedimentary gneiss in the Jack Hills of the Narryer Gneiss Terrane of Australia. 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 zircons from the Jack Hills have returned an age of 4.404 billion years, interpreted to be the age of crystallization and may be the currently oldest known terrestrial material on Earth.
Microslide Size: 75mm L X 25mm W X 4mm D, Microslide well size: 12mm Diameter.
Legally obtained in a scientific trade with a major scientific institution.
Ships in see-thru display case with information and authenticity. Stand and cube not included. Ships with Certificate of Authenticity, tag and perky display case.
Note: The zircons are relatively easy to see. There is enough material to fill up the
microslide well. The material is free and not encased in lucite.
