Members of NAI 's University of Wisconsin, Madison team have a new paper in Earth and Planetary Science Letters presenting their analyses of 4.35 - 3.36 billion year old detrital zircons from the Jack Hills, Western Australia. Their data reveal relatively high lithium abundances compared to other zircons, as well as lithium isotope ratios that are similar to continental crust weathering.. A zircon from the Jack Hills in Western Australia was claimed to be 4.4 billion years old 13, but the age has proven contentious and is thought to reflect post-crystallization modification.Valley.

The composition and origin of Earth's early crust remains hotly debated. Here we use partition coefficients to invert the trace element composition of 4.3-3.3 Gyr Jack Hills zircons to.. The rough, sedimentary layers of the Jack Hills formation are 3.3 billion years old, but they also contain much older zircon crystals across a range of time from 3.6 to nearly 4.4 billion years old. The specimen measures 1x1 cm and is enclosed inside an acrylic specimen jar. The jar is enclosed inside a classic, glass-topped riker display case.
