A septarian concretion is a mass of rock divided internally by thin septa of another mineral that usually appear to radiate from the center. Septarians can form when a mass of material such as clay with a high water content becomes embedded in a matrix that contains less water. The clay shrinks as it dehydrates, creating internal cracks in the ...

The exact mechanism for how the cracks form in the concretions is a mystery.The main difference between a geode and a thunderegg is that a geode is composed of crystals with a hollow inside, while a thunderegg is solid. Thunderegg has defined rock and mineral composition.

Septarian or septarian nodules are concretions containing angular cavities or cracks, called "septaria" which have become filled with calcite and aragonite. A concretion is a hard, compact mass of rock that often forms around decaying organic matter. In the case of septarian nodules the concretions formed around decaying sea-life in a marine environment.The process that created the septaria, which characterize septarian concretions, remains a mystery. A number of mechanisms, i.e. the dehydration of clay-rich, gel-rich, or organic-rich cores; shrinkage of the concretion's center; expansion of gases produced by the decay of organic matter; brittle fracturing or shrinkage of the concretion interior by either earthquakes or compaction; and others ... Septarian carbonate concretions contain carbonate precipitated during progressive growth of the concretion and subsequent fracture-filling. As such, they have been used to track variations in δ 13 C and δ 18 O of pore waters during diagenesis and to define diagenetic zones in clastic rocks. However, the δ 18 O value of the carbonate is dependent on precipitation temperature and the δ<SUP ...SW Michigan 161g Septarian Concretion Nodule MUST SEE $ 19.04.
