Concretions can have regular shapes like blocks, boxes, pipes, flat discs, canon balls, or even resemble parts of a human body such as a foot or rib. It is sometimes hard to believe that they formed by natural processes. Ironstone concretions are common around Sydney, with its outcrops of iron-rich shale and sandstone. Formation of concretionsThese concretions are classified into five types based on size, shape, and mode of occurrences in the outcrops. The small irregular (n = 6) and large massive (n = 5) concretions are mainly from the Lower Unit, whereas the thin-stratified (n = 4) concretions are from the Middle Unit, and the.

Iron oxide concretions are formed from post depositional, paleogroundwater chemical interaction with iron minerals in porous sedimentary rocks. The concretions record a history of iron mobilization and precipitation caused by changes in pH, oxidation conditions, and activity of bacteria.

These are formed of pyrite or marcasite, creating a roughly spherical concretion. They’re called pop rocks because they have a tendency to explode when thrown in a fire. When struck, the iron sulfide generally sparks as well. 8am pst to mountain time Concretions are composed of a localized mass of cement (e.g., ferric oxide) that precipitates in pore spaces during diagenesis in sedimentary rocks.
