Four columnar samples of this reservoir-bottom sediment were collected. Each columnar sample was subjected to facies, pH, redox potential measurement, color measurement, and detailed observation of the red part. The results showed the following: (1) most weathered layers were located above the sand layer and in the zone of groundwater-surface fluctuation; (2) for the model of the reddening mechanism, the process of diffusion-supply in the pore water of the sand layer could be applied, but it was necessary to consider the involvement of microorganisms such as sulfate-reducing bacteria and iron-oxidizing bacteria in addition to the inorganic redox reaction; and (3) among the color data, chroma was found to be a useful indicator of the progress of chemical weathering (iron oxide formation). Based on these results, the potential of the Nanatsu-ike Pond sediments for geoscience educational materials is discussed.","subitem_description_language":"en"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"広島大学総合博物館","subitem_publisher_language":"ja"},{"subitem_publisher":"Hiroshima
