The Dixon Island Formation was situated in an immature island arc setting andcomprises siliceous, carbonaceous deep-water sediments that contain evidence for hydrothermal andmicrobial activity. The extensive outcrop along the coastline makes it possible to examine in detail thecharacteristics of Mesoarchean sedimentation in a hydrothermal environment. This study focuses on acontinuously exposed carbonaceous, black chert succession in the central part of the northern coastlineoutcrop on Dixon Island. At this site, a 20-m-thick, carbonaceous, black chert sequence conformablyoverlies basement rocks of highly altered komatiite–rhyolite tuffs. The black chert sequence formedwell-bedded black chert with carbonaceous peloidal matter and fragmented grains, and the sequence ishomogeneous and finely laminated. In this sequence, evidence of low-temperature hydrothermal fluid,sediments and alteration stractures are well preserved in the lowermost section, indicating that high lev-els of hydrothermal activity occurred on the ocean floor during deposition. In particular, swarms of blackchert veins provide evidence of post-volcanic hydrothermal activity that released organic matter andsilica to the ocean. The carbonaceous peloidal textures and 13Corgvalues of sediments located just abovethe basement, which hosts the vein swarms, suggest that the veins were the conduits for hydrothermalfluid which contained organic-rich silica material and that flowed onto the seafloor to form the homo-geneous carbonaceous cherts along with hydrothermal-related sediment. The 13Corgvalues of organicmatter in the black cherts range from −42‰ to −22‰ (average = −31.9‰; n = 313). Lighter 13C values(−35‰ to −42‰) characterize carbonaceous laminated black chert located ∼5 m above the basement,where biogenic structures (e.g. biomat bed, microfossil structures) are found. The lighter 13C valuesmight be related to methanotrophic micro-organic activity within the sediments during hydrothermalactivity. In summary, we reconstructed the sedimentary environment upon a Mesoarchean hydrothermalocean floor that was a site of microbial activity and local methanogenesis.© 2014 Elsevier.

When we reconstructed Archean-Proterozoic environments, deep ocean sequence is good key sequence to recognized the surface environment. Many place have been reported of the black chert to Iron rich sediments above volcanic sequence.
Following area, we researched detail about stratigraphy at the oceanic sequence. These area preserved deeper sedimentary environment at that ages.
[Archean] 1) Dixon Island-Cleaverville formations in West Pilbara, Australia, 2) Mappepe Formation in Barberton, South Africa. Especially, we did scientific drilling in Pilbara, which is called “ DXCL drilling project”, at 2007 and 2011 summer.
[Proterozoic] 1) Cape three point, Ashanti belt, Ghana, 2) Cape Smith belt, Quebec, Canada, 3) Flin Flon belt, Manitoba, Canada, 4) El Dabbah iron formation, East Egypt.
A systematic combinations of geological, sedimentological, geochemical, and geobiological approaches will be applied to the fresh samples along the coast, mine and drilling core. We will understand the influence of submarine hydrothermal activity on the biological and chemical evidence and take original depositional environmental information at the time. Here we shows overview of our projects and some result such as DXCL drilling, Mappepe formation and Ghana Greenstone Project.

Nyame, Reconstructed Oceanic Sedimentary Sequence in the Cape Three Points Area, Southern Axim-Konongo (Ashanti) Greenstone Belt in the Paleoproterozoic Birimian of Ghana. , AGU, 2014.12, The Birimian greenstone belt likely formed through collision between the West African and Congo Cratons ~2.2 Ga. Accreted greenstone belts that formed through collision especially during the Palaeoproterozoic are usually not only good targets for preservation of oceanic sedimentary sequences but also greatly help understand the nature of the Paleoproterozoic deeper oceanic environments. In this study, we focused on the coastal area around Cape Three Points at the southernmost part of the Axim-Konongo (Ashanti) greenstone belt in Ghana where excellently preserved Paleoprotrozoic deeper oceanic sedimentary sequences extensively outcrop. Kwtakor zone (> 150m) is the thickest volcaniclastic sequence and has fining upward sections. Akodaa zone (> 150m) consists of finer bed of volcaniclastics with black shales and has fining upward character. This continuous sequence indicate distal portion of submarine volcaniclastic section in an oceanic island arc between the West African and Congo Cratons..
