Green spherical materials and remnants of dead microbial cells of filamentous bacteria are abundant in the green marine clays. Organic carbon and graphite were found in the volcanic sandstone. Transmission electron microscope observations clearly show processes of graphite mineralization from low-crystallinity to well-crystallized graphite. However, X-ray photoelectron spectrochemical analyses (micro-ESCA) indicate that the green marine clays contain high C (1s) of microbial origin carbon, and COO, C---O, C---C and graphite structures. Fourier transform infrared spectra (FT-IR spectra) of the green spherules show peaks between glauconite and celadonite. X-ray powder diffraction data show the presence of smectite and 1.03-1.22-nm mica-clay minerals with abundant zeolites, which are hydrothermal alteration products. The results suggest that fossil remnants of graphite mineralized organisms, in particular filamentous bacteria, might play an important role in the formation of green marine clays. 140.8881 140.8881 31.10591 31.10591 140.8881 31.10591 1989-05-27T18:10:00 1989-06-17T18:55:00 1079.0 1227.0 vertical profile ODP Ocean Drilling Program https://www-odp.tamu.edu:443/ Ocean Drilling Program, Texas A&M University ODP http://www-odp.tamu.edu/ https://ror.org/01f5ytq51 126-793B 31.10591 140.8881 North Pacific Ocean -2975.0 1989-05-27T18:10:00 1989-06-17T18:55:00 Leg126 Leg126 1989-04-18T00:00:00 1989-04-18 1989-06-19T00:00:00 1989-06-19 Joides Resolution https://www-odp.tamu.edu:443/resolutn.html Taylor, Ben J Taylor, Ben J Fujioka, Kantaro Fujioka, Kantaro doi:10.2973/odp.proc.ir.126.1990 Joides Resolution https://www-odp.tamu.edu:443/resolutn.html Drilling/drill rig DRILL 1682 m 697.94 m 114 cores; 1095.5 m cored; 0 m drilled; 63.7 % recovery 36 CC-BY-3.0 Creative Commons Attribution 3.0 Unported https://creativecommons.org/licenses/by/3.0/ DEPTH, sediment/rock Depth sed m depth http://purl.obolibrary.org/obo/PATO_0001595 sediment http://purl.obolibrary.org/obo/ENVO_00002007 rock Length L http://dbpedia.org/resource/Length Depth sed [m] Sample code/label Sample label DSDP/ODP/IODP sample designation hdl:10013/epic.27914.d001 Tazaki Kazue Sample label Iron Fe % Dimensionless Ratio ψ X-ray photoelectron spectrochemical analysis Tazaki Kazue Fe [%] Oxygen, gas O2 % oxygen O https://www.ebi.ac.uk/chebi/searchId.do?chebiId=CHEBI:25805 gas Dimensionless Ratio ψ X-ray photoelectron spectrochemical analysis Tazaki Kazue O2 [%] Calcium Ca % calcium Ca https://www.ebi.ac.uk/chebi/searchId.do?chebiId=CHEBI:22984 Dimensionless Ratio ψ X-ray photoelectron spectrochemical analysis Tazaki Kazue Ca [%] Potassium K % potassium K Dimensionless Ratio ψ X-ray photoelectron spectrochemical analysis Tazaki Kazue K [%] Carbon, total TC % carbon C https://www.ebi.ac.uk/chebi/searchId.do?chebiId=CHEBI:27594 total https://www.oxforddictionaries.com/definition/american_english/total Dimensionless Ratio ψ X-ray photoelectron spectrochemical analysis Tazaki Kazue TC [%] Chlorine Cl % chlorine Cl Dimensionless Ratio ψ X-ray photoelectron spectrochemical analysis Tazaki Kazue Cl [%] Silicon Si % silicon Si https://www.ebi.ac.uk/chebi/searchId.do?chebiId=CHEBI:27573 Dimensionless Ratio ψ X-ray photoelectron spectrochemical analysis Tazaki Kazue Si [%] Aluminium Al % aluminium Al Dimensionless Ratio ψ X-ray photoelectron spectrochemical analysis Tazaki Kazue Al [%] supplement citable author33035 author33036 basis5 campaign3393488 campaign98 event13634 geocode1 geocode1599 geocode1600 geocode1601 geocode8128 inst34 journal3311 license101 method10974 method5059 method6287 param4929 param735 param74 param75 param77 param79 param790 param815 param90 pi33035 project3 ref29177 term1073131 term23838 term2662985 term38253 term38263 term38477 term38478 term38494 term38520 term40134 term40136 term41046 term41056 term43794 term43863 topotype3
