Peat - peat (English spelling)

Japanese: 泥炭 - でいたん(英語表記)peat
Peat - peat (English spelling)

Also known as grass peat, according to the JIS (Japanese Industrial Standards), it is formed when aquatic plants, mosses, and marsh grasses accumulate and undergo biochemical changes near the surface, and is common in extremely cold regions such as Hokkaido and Siberia where the period of microbial activity is relatively short. It is somewhere between wood and lignite. It is not usually classified as coal. As you move from the top to the bottom of the coal bed, it becomes a yellowish-brown porous material containing grass roots and bark, or a black-brown mud-like material. It contains a lot of water, but can be used as fuel when dried. It is also used as a raw material for producing feed for cattle and other animals.

Japanese:

草炭(そうたん)ともよばれ、JIS(ジス)(日本工業規格)では、水生植物、コケ類、湿地帯の草類が堆積(たいせき)し、生化学的変化を地表近くで受けて生成したものをいい、北海道、シベリアなど極寒地で微生物活動期間の比較的短いような地帯に多い。木材と褐炭の中間に位置する。普通は石炭に分類しない。炭層の上層から下層へ移るにしたがって草根樹皮などを含む黄褐色の多孔質から黒褐色泥状のものとなる。多量の水分を含んでいるが乾燥すれば燃料となる。ウシなどの飼料製造原料としての用途もある。
