About: Septarian Nodule, is a formation of Aragonite ~ the brown, Calcite ~ the yellow, Limestone ~ the grey, and Barite ~ white/clear. It can also be known as Dragon Stone (not the green and red dragon stone).
Septarian specimens are believed to have formed during the Cretaceous period, some 145 million years ago! Volcanic eruptions and other occurrences resulted in the death of small sealife that then sank to into the seabed. As the specimens decomposed, sediments would accumulate and create a nodule or mud ball. When the oceans eventually receded, these mud balls were left exposed to the air, dehydrated, causing shrinking and cracking. The beautiful patterns you see inside septarian nodules are the result of this cracking.
The word septarian comes from the Latin word "septum," meaning "partition." Septarian nodules contain angular cavities as a result of cracking, which are called septaria and create divisions throughout the stone. Calcite leeches into the cracks of septarian to form calcite crystals (druzy) on a layer of aragonite, which is on bentonite clay. Eventually, bentonite is replaced with limestone, resulting in the nodule turning to stone.
