SEPTARIA
Cut and polished slice of a septarian nodule

Orderville, Kane County, Utah, USA
 
Septarian nodules, or 'septaria', are remarkable natural objects.  They are round concretions containing a network of internal cracks that have been filled with minerals, particularly brown and yellow calcite. No traces of the cracks are visible on the surface of the nodule.  


The cracks are called ‘septa’ from the Latin word septum or ‘partition’, which gives the nodules their name.  Exactly how these nodules were formed is still not fully understood. 

When cut and polished these nodules can be very beautiful.  This example is from the classic site in Utah which has produced some of the finest septarian nodules in the world.

This slice is translucent when held uo to the light.
