Concreations rocks
All over the world, spectacular fossils have frequently been found preserved inside solid, roughly spherical rocks called "concretions." From geologists to casual observers, many have wondered why ...In addition to rocks and minerals, Kansas has a number of other formations that are best labeled "sedimentary structures." These formations, although composed of Kansas rocks and minerals, require additional explanation. Some, such as concretions or cone-in-cone, may be mistaken for fossils. Others, such as geodes, can be spectacularly beautiful.

Prices vary depending on the size, type of minerals, and type of crystals. You might find smaller septarian geodes for $20 to $90, with larger and more intricate specimens ranging from $100 to $500. In rocks highly rich in magnetite-hematite nodules, some parts of the the rock may attract a magnet and other parts may not. Hematite is easy to identify because it makes a red streak. Also, hematite concretions are denser (heavier for their size) than any kind of stony meteorite or most other kinds of Earth rocks. Concretions in Kansas are formed from any of a number of minerals, including calcite, limonite, barite, pyrite, or silica.
