Carbonaceous Filaments from North Pole, Western Australia: Are They Fossil Bacteria in Archean Stromatolites? a Discussion
نویسنده
چکیده
Some time ago Buick (1984) cast doubt on both the biogenicity and the age of the objects we described as Early Archean bacterial microfossils in a previous paper (Awramik et al., 1983). He presented new evidence significant to the interpretation of these objects, but his report also contains statements that may be misleading. We wish to comment on his new evidence and to correct the misleading statements. Our initial report (Awramik et al., 1983 ) has been supplemented by a detailed discussion of all Archean microfossils and microfossil-like objects (Schopf and Walter, 1983). This latter paper describes the history of the discoveries at North Pole (Western Australia) and sets out in detail the evidence for biogenicity, syngenicity and age of the microfossils and possible microfossils. New observations have been presented by Awramik (1984), and additional relevant geochronological information has been published by Richards et al. (1981) in a paper that was not available to us when our initial reports were prepared.

Oxygen-Dependent Morphogenesis of Modern Clumped Photosynthetic Mats and Implications for the Archean Stromatolite Record
Some modern filamentous oxygenic photosynthetic bacteria (cyanobacteria) form macroscopic tufts, laminated cones and ridges that are very similar to some Archean and Proterozoic stromatolites. However, it remains unclear whether microbes that constructed Archean clumps, tufts, cones and ridges also produced oxygen. Here, we address this question by examining the physiology of cyanobacterial clu...

Modern Subsurface Bacteria in Pristine 2.7 Ga-Old Fossil Stromatolite Drillcore Samples from the Fortescue Group, Western Australia
BACKGROUND Several abiotic processes leading to the formation of life-like signatures or later contamination with actual biogenic traces can blur the interpretation of the earliest fossil record. In recent years, a large body of evidence showing the occurrence of diverse and active microbial communities in the terrestrial subsurface has accumulated. Considering the time elapsed since Archaean s...

The 3.45-billion-year-old Strelley Pool Formation of Western Australia preserves stromatolites that are considered among the oldest evidence for life on Earth. In places of exceptional preservation, these stromatolites contain laminae rich in organic carbon, interpreted as the fossil remains of ancient microbial mats. To better understand the biogeochemistry of these rocks, we performed microsc...

Bitumens extracted from 2.7 to 2.5 billion-year-old (Ga) shales of the Fortescue and Hamersley Groups in the Pilbara Craton, Western Australia, contain traces of molecular fossils. Based on a combination of molecular characteristics typical of many Precambrian bitumens, their consistently and unusually high thermal maturities, and their widespread distribution throughout the Hamersley Basin, th...
