This is one of the best specimens I found at the 2014 Quartzite, Arizona, Gem and Mineral Show. Septarian Concretion or Septarian nodules 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 Nevada where many of the Septarian nodules are found.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 ... A new hypothesis for concretion growth and septarian cracking argues that quasi‐rigid 'proto‐concretions' formed via binding of flocculated clays by bacterial extracellular polysaccharide substances (EPS). This provided rheological and chemical conditions for tensional failure, subcritical crack growth, volume contraction, calcite ...Painting a concrete floor is one way to change the look and feel of a room or spruce up an older, worn concrete floor. If you want a fresh look that’s durable, it’s a good idea to use epoxy paint for concrete floors.Septarian nodules formed as a result of volcanic eruptions and compressed matter of Dead Sea creatures. Therefore, the bonds of Septarian nodules are formed in sediment through the “concretion” of mud masses and mixed organic material. Septarian nodules originate from the Cretaceous period and formed anywhere between 50 to 70 million years ago!

It’s durable, easy to maintain and looks as cool as it feels to the touch. Concrete is also versatile.

Welcome to our Septarian Concretion page! Septarians were formed approximately 110 million years ago when the Gulf of Mexico reached what is now southern Utah. Decomposing sea (shell) life, killed by volcanic actions had a chemical attraction for the sediment around them, forming mud balls. Tide and wave action rolled the balls around ...Septarian nodules are a strange form of concretion. They’re round nodules with an exterior that has white lines cutting through them. These often resemble a turtle’s shell and when polished they present a visually complicated array of minerals.
