Most often the cementing mineral is calcite, but the brown, iron-bearing carbonate mineral siderite is also common. Some concretions have a central particle, such as a fossil, that triggered the cementation. Mazon Creek Fossil Flora. The Mazon Creek fossil deposit extends over a wide area of northeastern Illinois.

Concretions can also form by building up of successive layers of material around a nucleus (sand grain, pebble, mineral crystal, fossil or human-made object). Ground water with dissolved iron, silicon, calcium or other chemicals will often drop these as iron oxide, calcium carbonate or silica solids when chemical conditions change, adding them ... Fossil inside a concretion How Are Concretions Formed? Concretions are formed through the precipitation of minerals in sediment before it hardens. Essentially, they became mineralized before the rest of the surrounding rock. Concretions form early on in the sedimentary stone cycle if they're present.

The water-saturated concretion is stressed differentially when it is frozen, creating weakness along the plane of the fossil, wherever in the concretion that may be. It may take many cycles of freeze tha w to succeed in developing a fracture along the plane of the fossil, and some concretions never do succumb.

Biomimetic helical concretions occur on the shore of Ikalukrok Creek, Alaska. These concretions consist of radiating aggregates of elongate calcite crystals. Both spheroidal and helical concretions form by spherulitic crystallization. A concretion is a compact mass of mineral matter, usually spherical or disk-shaped, embedded in a host rock of a different composition.
