Septarian Eggs start out as concretions, which are basically solidified balls of mud. Concretions generally form around a nucleus of organic matter, such as a shell and are almost always found in sedimentary rocks that were deposited underwater.
These concretions then become cracked through geological processes. Mineral rich fluids seeping through the surrounding rocks deposit minerals within the cracks. Typically siderite or aragonite gets deposited first and then calcite crystals grow on top of these deposits. The mineral/crystal filled cracks are known as “septa”. It is still under debate exactly how the cracks in the concretions occur, but many mechanisms have been proposed. Dehydration and resulting shrinkage of the concretions; expansion of gases produced by the decay of organic matter of the concretions core; fracturing due to earthquakes; or some other yet to be determined process(es). Sometimes larger, crystal filled voids will remain at the center of septarian nodules, which would technically make them geodes. The presence of these voids would seem to point to some gas expansion, rather than shrinkage being involved in their creation.
