Septarian or septarian nodules are concretions containing cracks and cavities that were filled in with minerals such as calcite (yellow) and aragonite (brown) causing the very unique patterns. These septarian nodules make for very interesting display pieces when cut and polished. Directions to Muddy Creek Septarian Nodule Dig: 1. Drive South on I-15 for 177 miles to the turnoff for US-20 (exit 95) 2. Turn left (East) onto US-20 toward US-89/Panguitch/Kanab. 3. Drive 20.5 miles on US-20 until you run into US-89. Turn right (South) onto US-89 and drive 10.1 miles into the town of Panguitch. 4. Septarian nodules are a type of concretion. Mudstone combines with calcite or another carbonate-rich mineral, and the calcite follows the pattern of radiating cracks that grow during the stone's formation. In every case, septarian nodules are comprised of at least two minerals. The matrix of these nodules is often grey.Sellés-Martinez (1996) proposed that it is possible for septarian cracks to develop due to the increase of stress around a stiff concretion in plastic sediment, suggesting that overpressuring is ...

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 …Septarian concretions are abundant in many Phanerozoic marine and marginal-marine shales and mudstones. They range from a few centimetres to several metres in size and are spherical or ellipsoidal in morphology. In general, formation by localized calcite or siderite cementation in argillaceous sediments began under less than a few metres of burial.A cross section through a septarian nodule showing the network of calcite-filled cracks or septa. From Sowerby’s British Mineralogy (1804) Smaller septarian nodules from British Jurassic clays such as the Kimmeridge Clay are capable of being cut in half and polished to reveal the colourful network of cracks.

It's not a fossil. A concretion is not a fossil itself. Some call concretions pseudo fossils.

When the oceans receded, the balls dried and ... ….

ku football score now Septarian concretions or septarian nodules are sometimes called Dragon Eggs. They form primarily in an ocean setting just below the sediment surface through a series of steps. Some sort of nucleus, such as a fossil, is buried in the sediment. Fine grained calcite mud precipitates around this nucleus and a hard mud ball is formed. The longer the ocean level stays relatively constant, the bigger ...

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 ...Septarian nodules are a type of concretion with cracks that become filled with minerals, in this case, calcite.
