appearance and behavior during combustion. It is characterized by a high
percentage of algal remains and volatile matter. Upon distillation it
gives exceptionally high yields of tar and oil. See also:cannel coal;

of algae, and having less than 5% anthraxylon. AGI

a. A general term for a soft, spongy, and porous deposit of impure hydrous
iron oxides formed in bogs, marshes, swamps, peat mosses, and shallow
lakes by precipitation from iron-bearing waters and by the oxidizing
action of algae, iron bacteria, or the atmosphere; a bog ore composed
principally of limonite that is commonly impregnated with plant debris,
clay, and clastic material. It is a poor-quality iron ore, in tubular,
pisolitic, nodular, concretionary, or thinly layered bodies, or in
irregular aggregates, in level sandy soils, and esp. abundant in the
glaciated northern regions of North America and Europe (Scandinavia).
Syn:limnite; morass ore; meadow ore; marsh ore; lake ore; swamp ore.

A vernacular name for peat. Tomkeieff
Oak immersed in peat bogs, semifossilized and blackened to resemble ebony
by iron from the water combining with the tannin of the oak. CMD
a. A spongy variety of hydrated oxide of iron and limonite. Found in
layers and lumps on level sandy soils that have been covered with swamp or
bog. Includes bog iron ore, bog manganese ore, and bog lime, a calcareous
deposit of similar origin. See also:brown iron ore
b. A poorly stratified accumulation of earthy metallic-mineral substances,
mainly oxyhydroxides, formed in bogs, marshes, swamps, and other low-lying
moist places, by direct chemical precipitation from surface or
near-surface percolating waters; specif. "bog iron" and "bog manganese".
