| 内容記述 | The western part of Tōnō district of Gifu Prefecture is well known as one of the locality of fireclay("Kibushi" clay)in Tokai region, japan. Nakayama fireclay mine is situated in the southern part between the Toki and Tajime city. This area composed of the lower Pliocene, the Tokiguchi clay formation, which was overlaying on the Meso and/or Paleozoic and Miocene basement rocks. The Tokiguchi clay formation is assumed as non-marine sediments in concave on the basement rock. "Kibushi" clay beds are intercalated in the Tokiguchi clay formation accompanying with lignite seams and are covered by the Toki gravel formation as a role of cap rock. The writers have been carried out the mapping\ of the cross section of mine at main six portions. In order to identified the formation of ore deposit, the distribution state of "Kibushi" clay beds are considered to be controlled by the paleo-topography of basement rocks, and are the most useful key bed for sedimentary process. Three "Kibushi" clay beds occur associated with lignite seams in this mine. The lower layer distributed at only the northern part of the area. The middle layer is distributed over the area extending mostly along the valley of west to east direction. and can be observed in every profiles of ore deposit. The most workable thickness of this layer, ranging from 6 to 9 meters, are maximum in comparison with those of other two layers. The upper layer is extinguished at the southern part of the area. Further, mineralogical study of four profiles of ore deposit have been investigated, schmatically. In profile, clay formation can be classfied into the following zones from the bed rock to the surface(depth about 20m):bluish grey sandy clay, lower "Kibushi" clay, grey sandy clay, middle "Kibushi clay, white grey sandy clay, upper" Kibushi clay and grey sandy clay. The uppermost zone is covered by the gravel zone. In general, the sandy clay predominate in the deposit, as a whole. The clay formation is chiefly composed of kaolinite and fine grained quartz accompanying small amounts of feldespar. Moreover, most of clayey materials contain a little quantity of montmorillonite and illite. These mineral assemblages in this mine are similar to that of other "Kibushi" clay deposits. However, montmorillonite is assumed to be derived from other source materials. On the other hand, general inclination of paleo-topography of basement in this area trend toward the western side, therefore, residual substances originating from weathered granite were transported from the eastern side area. The white clay bed (about 20cm in thickness) occurs at a specific horaizon in the upper sandy zone. This clay is named "Shinmei kaolin" which consists of halloysite. This was probably formed diagenetically from volcanic ash.@@@岐阜県中山鉱山地域の陶土層は中・古生層および中新統を基盤とする凹地に土岐口陶土層が堆積したものである。陶土層の胚胎状況は基盤の古地形に支配されるもののようで、基盤の地形を基に鉱床断面図を作成した。鉱体の木節粘土は3層準分布しており、当中山鉱山周辺ではその下部層は層厚約4m、北部のみに分布しほとんど連続しないが、中部層は比較的良く連続し、層厚は最大6m、西部で薄くなる。上部層は北東から南西にかけて分布し層厚は約4mを示す。また本地域の基盤は西に下る傾向をなすことから、当陶土層の供給物は東から運ばれたことがわかる。一方鉱床プロファイルは下位から上位にかけて、砂質粘土、木節粘土層、砂礫層からなる。木節粘土層は亜炭層を同層準間に挾み3層分布する。陶土層を構成する主な鉱物はカオリン、石英で少量の長石を含み、モンモリロナイト、イライトがかなり普遍的に含まれる。また本鉱床には“神明カオリン”とよばれる白色粘土層を産出するが、この粘土の構成鉱物はハロイサイトである。なお粘土層のカオリナイトは不整が著しくまた結晶度も悪く、指数値は他地域の同型堆積性鉱床のものとほとんど同じ範囲内にある。 |
