Trovants are spherical and slightly irregular-shaped rocks. They can be as small as less than an inch, or a couple of millimeters, in diameter and weigh only a few grams, or they can soar up to 15 feet (4.5 meters) high and weigh several tons. These odd, gravity-defying boulders have baffled observers since the 18th century with many a curious ...We’ll move on to the next steps which involve observing the outer appearance of the potential geode. 2. Check for a roughly spheroidal, rounded shape. The shape of a rock is one of the best indicators of whether or not it could be a geode. Due to how they are formed, geodes are almost always pretty well rounded.

Some limestone has formed around artifacts known to be from the 20th century, so concretions can form fairly quickly around objects, he said.

The forming rock may have slowly rolled from time to time along the ocean floor, smoothing it as it grew, becoming what is now termed – concretion.

Concretions are naturally occurring circular to oval-shaped mineral deposits in rock. Concretions form when mineral layers grow or “accrete” around an organic or mineral particle in sediment. If minerals fill a burrow or void in the sediment, growth will generally conform to the shape of the mineral or void.Geodes, Nodules, Vugs, Concretions and Thundereggs. Geodes, nodules, vugs, concretions and thundereggs are all sites in the earth where substances dissolved in subsurface waters precipitate to form crystals or rounded objects. These objects share many common features and form by similar processes.Concretions Composed of a carbonate mineral such as calcite. A concretion is a compact mass of mineral matter, usually spherical or disk-shaped, embedded in a host rock of a different composition. This hard, round mass of sedimentary rock cement is carried into place by ground water.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.
