A local concentration of chemical compounds (e g calcium carbonate, iron oxide) in the form of a grain or nodule of varying size, shape, hardness, and color Concretions of significance in hydric soils are usually iron and/or manganese oxides occurring at or near the soil surface, which develop under conditions of prolonged soil saturation
A hard round, oval, or other-shaped of mass of mineral or aggregate matter of varying sizes Commonly forms by chemical precipitation around a nucleus or center, or replacement of precursor organic or inorganic material An example is siderite (iron, calcium carbonate) concretions
Spherical to elliptical nodules, harder than the surrounding rock, formed by accumulation of mineral matter (example - iron oxide) after deposition of sedimentary rock
