Shoichi Kiyokawa, Takashi Kuratomi, Tatsuhiko Hoshino, Shusaku Goto, Minoru Ikehara, Hydrothermal formation of iron-oxyhydroxide chimney mounds in a shallow semi-enclosed bay at Satsuma Iwo-Jima Island, Kagoshima, Japan, Geological Society of America Bulletin, https://doi .org/10.1130/B35782.1., 133, 9-10, 1890-1908, 2021.09, Hydrothermal iron-oxyhydroxide chimney mounds (iron mounds) have been discovered in a fishing port in Nagahama Bay, located on the southwest coast of Satsuma Iwo-Jima Island, south of Kyushu Island, Japan. In the fishing port uncovered ~1.0 m-high iron mounds in shallow waters formed under relatively calm conditions. Typically, the fishing port has orange-colored turbid waters that mix with outer ocean waters during high tide. Colloidal iron-oxyhydroxides form due to the oxidation of ferrous iron in hydrothermal waters (pH = 5.5; temperature = 55°C) as they mix with seawater. The mounds are made of two types of material: hard, dark brown-orange, high-density material; and soft, brownish orange-yellow, low-density material. Computed Tomography (CT) scans of the harder iron mound material reveal a cabbage-like structure comprising micro-pipe structures with diameters of 2–5 mm. These micro-pipes have relatively hard walls made of iron oxyhydroxides (FeOH) and are identified as discharge pipes. Nucleic acid staining genetic sequencing and SEM observations suggest that the mounds formed mainly from bacterial stalks with high concentrations of FeOH colloidal matter. In the harder parts of the mounds, these ‘fat stalks’, which contain oxyhydroxide colloidal aggregates, are entwined and concentrated. The softer material contains twisted stalk-like structures, which are coated with FeOH colloidal particles. DNA examination of the iron mounds reveals the presence of iron oxidizing bacteria, especially at the mound surface. We estimate that the iron mounds accumulated at a rate of ~1,700 tons/1000 m2/year. This is an order of magnitude higher than the rate of FeOH sedimentation via chemical precipitation of FeOH colloids within the fishing port. This suggests that biogenic activity, resulting in the production of entwined FeOH stalks, leads to the rapid accumulation of FeOH beds and that biogenic activity within the water mass rich in FeOH colloids is an efficient means of generating thick iron-rich sedimentary sequences. As such, we propose that some ancient iron formations may have also formed through the biogenic production of FeOH stalks rather than solely through chemical sedimentation in a water mass rich in FeOH colloids. It appears that these rapidly forming biogenic FeOH iron mounds distributed wide area of ocean floor are also relatively protected from erosion and diagenetic alteration (reduction). Previous studies have reported that ancient iron formations were commonly deposited in deeper environments via direct iron oxidation from the water column in ferruginous ocean; however, There are several hydrothermal vents inflows preserved with FeOH that would have formed appropriate redox boundary conditions in an otherwise anoxic ocean. Under these conditions, iron mound mat-type sedimentary deposits might have formed and been well-preserved and affected by early diagenesis where higher heat flow occurred in the Archean ocean. The FeOH mounds in Nagahama bay shows an example of the iron formation sedimentary environment and leaves important information for estimating the past depositional state of iron formations..

These bacteria accelerate iron oxidizing by excreting unique organic structures that adsorb ferrihydrites. They form mat-like ferrihydrites in iron-rich hydrothermal environments of different depths of the oceans around the world. The process in the microbial mat associated with the modern hydrothermal activity can be regarded as a type of the biomineralization. Comparisons in iron oxide fabrics and bacterial habits in different hydrothermal settings improve our understanding for the formational mechanisms of iron oxides, including a wide range of ancient deposits, such as the Precambrian banded iron formations (BIFs) and oolitic iron ore. Previous studies have linked the BIFs with the long-term global environment changes, such as increasing oxygen level. Iron oxidizing bacteria was potential for forming the BIFs. Assuming that a single cell can oxidize Fe of 1.1 x 10-11 mole/year, activity of the iron oxidizing bacteria with the abundance of 5.7 x 104 cell/cm3 could generate the Precambrian BIFs. The biomineralization of the iron oxidizing bacteria was an important process forming the iron ores..

For example, the early Earth’s seawater sulfate level, which is thought to have close relationship with contemporary atmospheric oxygen level, can be estimated by analyzing sulfur isotopic ratio. Here, we show studies especially about the estimation of ancient seawater sulfate level and summarize the trend of studies so far. It is well known that the size of a gap of isotopic ratio between sulfate and sulfide in stratum depends on the sulfate reduction rate and seawater sulfate levels. For quantifying the sulfate levels, incubation experiments of sulfate reducing bacteria or model calculations have been in progress. However, different researchers have represented different arguments because of various methods or approaches. Looking at the trend of isotopic studies in recent years, the view in which Archean sulfate level (

We measured U-Pb ages on detrital zircon grains from Kumasi group sandstone with LA-ICP-MS to improve the understanding of the crustal evolution. The results for 43 samples indicated a single peak of 2163 Ma, coinciding with the age of granitic intrusions, implying that Kumasi Group sedimentation occurred after erosion and weathering of these granitic rocks..

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.
