The recent discovery of diamond–graphite inclusions in the Earth’s oldest zircon grains (formed up to 4,252 Myr ago) from the Jack Hills metasediments in Western Australia provides a unique opportunity to investigate Earth’s earliest known carbon reservoir. Here we report ion microprobe analyses of the carbon isotope composition of these diamond–graphite inclusions. The observed δ13CPDB values (expressed using the PeeDee Belemnite standard) range between -5 per mil and -58 per mil with a median… Expand
Potentially biogenic carbon preserved in a 4.1 billion-year-old zircon
TLDR
Carbon isotopic measurements on graphite inclusions from Jack Hills, Western Australia are reported to be consistent with a biogenic origin and may be evidence that a terrestrial biosphere had emerged by 4.1 Ga, or ∼300 My earlier than has been previously proposed. Expand
Diamonds in Earthʼs oldest zircons from Jack Hills conglomerate, Australia, are contamination
Abstract The earliest period of Earth history is the Hadean era (4600–4000 Myr) but to date no rocks are known to be preserved from this time. However, abundant detrital zircons from the Archean JackExpand
Diamonds through Time
Diamonds form in the upper mantle during episodic events and have been transported to the Earth’s surface from at least the Archean to the Phanerozoic. Small diamonds occur as inclusions in robustExpand
Hadean Jack Hills Zircon Geochemistry
Geochemical analysis of zircons older than 4 billion years, found in Early Archean metasediments at Jack Hills, Western Australia, provide insights into the nature of Hadean Earth. Oxygen isotopesExpand
The role of detrital zircons in Hadean crustal research
Abstract Meso-Archean sedimentary sequences at Mt. Narryer and the Jack Hills of the Narryer Terrane in Western Australia's Yilgarn Craton contain detrital zircon grains with ages as old as 4.37 Ga,Expand

What can Hadean detrital zircon really tell us? A critical evaluation of their geochronology with implications for the interpretation of oxygen and hafnium isotopes
Abstract Rare Hadean zircon grains represent the only direct sample of the Earth older than 4.0 Ga. As such, they have tremendous potential to illuminate our knowledge of this period of Earth'sExpand

Hadean diamonds in zircon from Jack Hills, Western Australia
TLDR
Mineralogical features of the Jack Hills diamonds resemble those of diamonds formed during ultrahigh-pressure metamorphism and imply a relatively thick continental lithosphere and crust–mantle interaction at least 4,250 million years ago. Expand
Stable Isotopes and the Origin of Diamond
Most diamonds form in a relatively narrow depth interval of Earth's subcontinental mantle between 150 and 250 km. From carbon isotope analyses of diamond obtained in the 1970s, it was first proposedExpand
Evidence for Multiple Sources of Diamond from Primitive Chondrites
TLDR
The data suggest that intrinsic differences must have been inherited by the diamonds at the time of their formation and that the diamonds were distributed heterogeneously in the solar nebula during condensation, and the hypothesis that a distinct nitrogen carrier remains hidden within the diamond cannot be ruled out.
