Any rock containing a substantial proportion of an iron compound, or any
iron ore from which the metal may be smelted commercially; specif., an
iron-rich sedimentary rock, either deposited directly as a ferruginous
sediment or resulting from chemical replacement. The term is customarily
applied to a hard, coarsely banded or nonbanded, and noncherty sedimentary
rock of post-Precambrian age, in contrast with iron formation. The iron
minerals may be oxides (limonite, hematite, magnetite), carbonate
(siderite), or silicate (chamosite); most ironstones containing iron
oxides or chamosite are oolitic. See:clay ironstone; banded ironstone.
CF:iron formation
A surficial or near-surface sheet or cap of concretionary clay ironstone.
