摘要已知在日本和新西兰的火山灰土壤中广泛存在尿磷酸盐。然而，对其性质的确切认识还没有很好地建立起来，主要是因为在纯态下分离它极其困难，而且它的x-非晶态性质。在对土壤尿磷脂的研究过程中，人们注意到某些安多土壤除了含有结晶粘土矿物和游离倍半氧化物外，还含有两种不同的矿物胶体。X-射线分析表明，其中一种胶体为x-无定形胶体，称为四氯化铝，另一种为结晶度较低的未知胶体。伊莫戈石*是作者在伊莫戈发现伊莫戈之后提出的第二种胶体的名称。伊莫戈是一种棕黄色的火山灰土壤。在熊本县的熊马盆地。当对土壤进行去铁处理时，尿磷矿在酸性和碱性介质中都分散，而蒙脱石在酸性介质中分散，在碱性介质中絮凝。
Abstract Allophane has been known to occur widely in volcanic ash soils in Japan and New Zealand. However, exact knowledge of its nature has not been well established, mainly because of extreme difficulty to separate it in pure state and of its x-amorphous nature. In the course of the studies on soil allophane, it was noticed that certain Ando soils contained two different mineral colloids together, in addition to crystalline clay minerals and free sesquioxides. X-ray examination revealed that one was x-amorphous colloid which would be called allophane, and the other an unknown colloid of low crystallinity. Imogolite*** was proposed as the name of the latter colloid by the present authors after imogo in which imogolite was first found. Imogo is a brownish yellow, volcanic ash soil. in the Kuma basin in the Kumamoto Prefecture3). When deferration treatment is applied to the soils, allophane disperses both in an acid and alkaline media, whereas imogolite disperses in an acid medium and flocculates in an alk...
