The Late Archean Biospheric Explosion
نویسندگان
چکیده
biogenic platform carbonates [4]. By c.2.45 Ga oxygen levels had begun to rise in the Earth’s atmosphere setting the stage for the evolution of the modern biosphere. Here we focus on concretionary structures, which can act as sensitive barometers of biological activity, to provide us with potential insights into the expansion of this early biosphere prior to the first appearance of oxygen in the atmosphere.

Nd isotopic evidence for the antiquity of the Wyoming province
Sm-Nd isotopic data on Late Archean age metasedimentary rocks from around the Wyoming province yield ENd values at 2.6 Ga from -12.9 to +3.3, which correspond to depleted mantle model ages of 2.7 to 3.8 Ga. These results indicate that crust of a wide variety of ages was exposed and eroding in Late Archean time. The predominance of Middle Archean model ages suggests that continental crust was ex...

High-resolution geochemical analyses of organic-rich shale and carbonate through the 2500 million-year-old Mount McRae Shale in the Hamersley Basin of northwestern Australia record changes in both the oxidation state of the surface ocean and the atmospheric composition. The Mount McRae record of sulfur isotopes captures the widespread and possibly permanent activation of the oxidative sulfur cy...

Highly cracked and isomerized archaeal lipids and bacterial lipids, structurally changed by thermal stress, are present in solvent extracts of 2,707- to 2,685-million-year-old (Ma) metasedimentary rocks from Timmins, ON, Canada. These lipids appear in conventional gas chromatograms as unresolved complex mixtures and include cyclic and acyclic biphytanes, C36-C39 derivatives of the biphytanes, a...

متن کاملProcesses on the Young Earth and the Habitats of Early Life
Conditions at the surface of the young (Hadean and early Archean) Earth were suitable for the emergence and evolution of life. After an initial hot period, surface temperatures in the late Hadean may have been clement beneath an atmosphere containing greenhouse gases over an ocean-dominated planetary surface. The first crust was mafic and it internally melted repeatedly to produce the felsic ro...
