Why is Idiwhaa Tonalitic Acasta Gneiss vital to understanding the Age of the Earth? Its incredible age gives us a crucial opportunity to fathom the conditions on early Earth. This metamorphosed rock outcrop is almost one-third the age of the Universe, and to know we can touch it is fantastic! This rock outcrop has been dated back to as early as 4.02 Ga. Bridging the gap between the Hadean and Archean, it is the oldest relic bedrock terrain on Earth. This is what makes it pivotal to understanding geologic time.

The formation of the Idiwhaa tonalitic Acasta Gneiss is an intriguing story of metamorphic processes, which occurred approximately four billion years ago. In contrast, the Jack Hills Zircon's formation is tied to sedimentary processes. The zircons were first incorporated into sedimentary rocks and then identified and dated by geologists to an age date for the oldest ones being nearly 4.4 Ga. Interestingly, rocks from the Nuvvuagittuq Greenstone Belt formed about 4.02 Ga. (See Nuvvuagittuq Greenstone Belt in our products list).
