Takashi Kozo - Takashi Kozo

Japanese: 高師小僧 - たかしこぞう
Takashi Kozo - Takashi Kozo

A ferric hydroxide or hydrous ferric phosphate mineral that is deposited around plant roots. There are also amorphous equivalents of these. A typical one is cylindrical, with a hollow interior due to rot of the roots. It has a brown earthy sheen. It is made of goethite with low crystallinity, and may also contain oxidation products of siderite and lazisite, and cacoxenite (Fe 3+ 24 Al [(OH) 12 |O 6 |(PO 4 ) 17 ] · 75H 2 O). It was named after the famous one from Takashihara, Aichi Prefecture. Although it contains a high iron content, it is not produced in large quantities, and since it also contains phosphorus, it is not used as iron ore.

Japanese:

植物の根などの周囲に沈着した水酸化第二鉄あるいは含水第二鉄燐(りん)酸塩鉱物。これらの非晶質相当相もある。典型的なものは筒状で、中の根が腐って中空になっている。外見は褐色土状光沢。結晶度の低い針(しん)鉄鉱からなり、菱(りょう)鉄鉱、藍(らん)鉄鉱の酸化産物、カコクセン石cacoxenite(Fe3+24Al[(OH)12|O6|(PO4)17]・~75H2O)などを含むこともある。愛知県高師原(たかしはら)のものが有名であったのでこの名がある。鉄含有量は高いが、多量に産するものではなく、また燐分が存在していたりするので、鉄鉱石としての用途はない。
