Bloom iron is a mass of malleable iron from which the slag has been beaten off.) In fact, England as a colonial power discouraged the manufacture of ironware in the colonies. Nonetheless, there was a flourishing domestic iron forge industry which produced a variety of goods including farm and domestic tools, nails, and particularly at the time.
A new model is presented for the origin of pisolitic iron ore deposits that gives credible explanation for the sedimentary and petrographic features of the deposits. Abstract Ooliths evidently form by chemical precipitation in limnic, paralic, fluvial and marine environments, pisoliths, however, appear to be restricted to terrestrial environments.
Pisolitic iron ores (aka channel iron deposits, CID) are a special case of transported pisolitic ferricrust that form an important resource of medium grade iron ore (57–60 wt Fe) in the Pilbara Region of Western Australia. Apart from minor deposits in the northern Yilgarn Province of Western Australia, they have not been found elsewhere.
