On the formation of telluric iron from bog ores

Article preview

In 1891, 20 versts northeast of Vologda, near the Church of St. Nicholas of Vozimsky (near Lake Kubinskoe), a piece of iron was found under a peat mass within a bed of bog ore, shallow from the surface. It was originally covered with a loose coating of ocher and immersed in the bog ore; its weight together with the ocher was 1100 grams. In some places it was permeated with rust to a certain depth. Freed from the ocherous shell, it took the shape of a spherical sector measuring about 10 centimeters wide and about 5 centimeters thick; it was veined and, in places, contained fine-grained inclusions of ocherous magnetic ironstone.
