The purposes of this investigation were to study on the chemical and mineralogical properties of materials sedimented on the mudflat area in mangrove swamp around Aira river at Iriomote island. Sediment samples were collected from inside and the edge of three different sites of land, middle and sea sides at 0-0.5cm and 0-10 cm depth levels in mangrove swamp. The results showed that the pH values of surface sediment changed from 3-6 and which were lower in the land side compared to other sides in mangrove swamp. The values of the EC were about 10-13mS/cm in middle side, however, those were higher in the sea side of mangrove swamp due to salt transmission form sea water. Total carbon content in mangrove swamp was about 2-6% and 1-5% of organic carbon occupied in 80% of the total carbon content and it was higher in the middle side. The values of chemical properties were higher in the most surface sedement in mangrove swamp. Both clay and silt content were higher in the most surface sediment in the middle side of mangrove swamp. The primary mineral of the silt fraction was mainly quartz in the surface sediment on either side. The secondary mineral of clay fraction was mainly kaolinite and accompanied by both illite and vermiculite even in either side of the surface sediment. From the above results, both materials of clay fraction and organic matter were highly accumulated in the most surface sediment in the middle side of which was affected by movement of tides and physiographic factor. It was suggested that the land formation highly progress in the middle side, contributing by the function of negatively charge humus and negatively and positively charge vermiculite.", "subitem_description_type": "Other"}, {"subitem_description": "\u7d00\u8981\u8ad6\u6587", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "jpn"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/3629"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "0370-4246"}, {"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN00250548"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8\u5b66\u8853\u5831\u544a"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "The Science Bulletin of the Faculty of Agriculture.
