Septarian nodules rock meaning or septarian gronates are concretions containing siderite and calcite angular cavities or cracks.

Septarian concretion were formed during the cretaceous period, around 50 to 70 million years ago. Sea levels were much higher then and the gulf of Mexico reached inland to Southern Utah where many of the stones are found. They are also found in Madagascar where conditions were similar.
Periodic volcanic eruptions killed the smaller sea life which sank to the sea bed and started decomposing. The minerals in the shells and carcasses attracted sea floor sediments which accumulated around the carcasses and formed nodules or mud balls.
When the ocean eventually receded, the mud balls dried out and began to shrink and crack into the beautiful patterns that you see inside the stones.
Septarian rock concretions are concretions containing siderite and calcite angular cavities or cracks, which are called “septaria”. The word comes from the Latin word septum, “partition”, and refers to the cracks/separations in this kind of rock.
There is an incorrect explanation that it comes from the Latin word for “seven”, septem, referring to the number of cracks that commonly occur. Cracks are highly variable in shape and volume, as well as the degree of shrinkage they indicate.
Although it has commonly been assumed that concretions grew incrementally from the inside outwards, the fact that radially oriented cracks taper towards the margins of septarian concretions is taken as evidence that in these cases the periphery was stiffer while the inside was softer.
Presumably due to a gradient in the amount of cement precipitated. The process that created the septaria, which characterize 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, have been proposed for the formation of septaria

How are septarian rock formed?
The stone formed as a result of volcanic eruptions and compressed matter of Dead Sea creatures. Therefore, the bonds of stones are formed in sediment through the “concretion” of mud masses and mixed organic material.
Are siderite septarian nodules rare?
Yes. You will only see these stones very rarely in certain collections.
Where are septarian nodules found?
Sometimes called lightning stones, it can also found on the Lake Michigan, USA, as well as in New Zealand, England, Morocco, and Madagascar.
How much is septarian worth?
One can obtain a stone for under $50 and even smaller specimens can be obtained for less. Septarian jewelry can be as affordable as obtaining a specimen.
