1.前言产于中部地区(名古屋通产局管辖的五县:石川、富山、岐阜、三重、爱知)的非金属矿物资源是多种多样的,目前进行开采(载入统计资料)的有23种(1983年)。如把某些同类矿物分别归入硅石、硅砂等,则分为以下17种: 1) 耐火粘土(页岩粘土、木节粘土);2) 叶蜡石;3) 长石;4) 白云石;5) 半花岗岩(细晶岩);6) 风化花岗岩;7) 陶石;8) 瓷土;9) 砂质粘土(经水洗、未经水洗两种);10) 硅石(白硅石、软硅石);11) 硅砂(未经水洗天然硅砂和经水洗天然硅砂,蛙目硅砂,人造硅砂);12) 硅粉;13) 石灰石;14) 熟耐火粘土(山麓型);15) 硅藻土;
1. Introduction Nonmetallic mineral resources produced in the central part of the country (Nagoya, Toyama, Gifu, Mie and Aichi) under the jurisdiction of the Nagoya Prefectural Office of Memorabilia are diversified and are currently being mined (included in statistical data) 23 species (1983). If some of the same minerals are classified as silica, silica sand, etc., are divided into the following 17 species: 1) refractory clay (shale clay, woody clay); 2) pyrophyllite; 3) feldspar; 4) dolomite ; 5) semi-granite (apatite); 6) weathering granite; 7) clay; 8) porcelain clay; 9) sandy clay (washed with water, ); 11) Silica sand (natural silica sand washed and washed with natural silica sand, frog silica sand, artificial silica sand); 12) silica fume; 13) limestone; 14) cooked refractory clay
