Objectives of the present paper was, as a series of research on the Jaagaru soils, to investigate clay mineralogy of the samples collected from three different horizons of Shirachichibaru soil, of which genesis was not yet identified in the Jaagaru area. The first horizon (0-40cm) consisted of reddish brown acid clayey material, the second horizon (150-200cm) was also acid but white and silty, and the third (500-550cm) was found to be bluish-gray, acid, and silty, but slightly effervescent with dilute hydrochloric acid. The clay fractions were investigated by means of selective dissolution, difference infrared spectroscopy, X-ray analysis, electron microcopy, and thermogravimetry. Obtained results were as follows : In the clay of the first horizon, the major cristalline minerals were Al-interlayering vermiculite and illite, accompanied by a small quantity of meta-halloysite and montmorillonite. Quartz was also contained. Amorphous minerals included free iron oxides and unidentified materials. It was assumed that the parent material of the horizon originated from Kunigami gravel or slate of Palaeozoic formation of which soils had similar clay mineralogy as reported by other investigators. The main crystalline minerals in the clay of the second horizon were meta-halloysite and halloysite, accompanied by a small quantity of illite. Quartz was not identified. Amorphous minerals were same with the above horizon. It was concluded that this horizon did not originate from the material of the underlying layer, but further studies were necessary to define a source of the horizon. A large quantity of montmorillonite and illite were found in the clay of the third horizon accompanying a small quantity of Al-interlayering vermiculite and meta-halloysite. The clay contained more quartz than that of the first horizon. Free iron oxides and unidentified materials were included in amorphous minerals as in the above horizon. This horizon was defined as derived from the marl of Shimajiri bed.","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/20.500.12000/4330"}]},"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.
