  • A major geochemical change that occurred 3.9 billion years ago, was probably related to a transition from impact-dominated to internal-heating-dominated thermal regimes on Earth, according to analysis of isotopic and geochemical data from dated detrital zircon crystals in the Jack Hills, Western Australia

  • A 3440 Ma old zircon entrained within a Proterozoic basaltic andesite dyke in Western Australia is identified through U-Pb geochronology and demonstrates that the mineral inclusion cargo of crystals within dykes can be a useful tool to probe hidden deep geology.
