When looking for concretions on the beach, look for round rocks with light colored stripes or markings. With concretions, the surrounding rock has begun to erode, exposing the encased fossil that’s inside. It is very common to find fossils of a variety of shells, shark teeth or even bone!

In sedimentary rocks, geodes may form by dissolving out cavities by ground water and re-depositing of minerals as crystals, which usually point towards the centre of the cavity. They may also form in pre-existing concretions or in spaces left by expansion of the rock under internal fluid pressure.

Single Pearl. Generally, calcareous concretions are valued much like pearls. Brighter colors and stronger saturations command higher prices. Rounds and ovals are more desirable, and other shapes are judged based on how symmetrical they appear. Smoother surfaces, higher luster, and larger sizes also increase value. Small septarian concretions are sometimes called "thunder-eggs." They can be found in many places; one of the best localities is one-half mile south of Hobbie Lake in Osborne County. Septarian Concretion, About the Size of a Volleyball, from North-Central Kansas. Geodes. Geodes, a type of concretion, are crystal-lined cavities in rocks.Mudstone is the result of millions of years of pressure on mud or clay-based soil. They’re also a common find in shale, another rock that was formerly clay but mixed in with other minerals. Shales generally form into layers that are easily separated.

Jan 12, 2021 · Calcite (calcium carbonate) is the most common cement for sandstone, but the bonding agent for concretions is a much more durable iron compound. As iron carbonate dissolves in groundwater, it precipitates around a fragment in the rock, such as a leaf, shell, bone, or fossil. The iron compound grows around this nucleus and a concretion begins.
