Nummalitic Limestone - Limestone often contains variable amounts of silica in the form of chert (chalcedony, flint, jasper, etc) or siliceous skeletal fragment (sponge spicules, diatoms, radiolarians), as well as varying amounts of clay, silt and sand sized terrestrial detritus carried in by rivers.
The primary source of the calcite in limestone is most commonly marine organisms. These organisms secrete shells made of aragonite or calcite and leave these shells behind after the organism dies. Some of these organisms can construct mounds of rock known as reefs, building upon past generations. Below about 3,000 meters, water pressure and temperature causes the dissolution of calcite to increase non-linearly so that limestone typically does not form in deeper waters.
Secondary calcite may also be deposited by supersaturated meteoric waters (groundwater that precipitates the material in caves). This produces speleothems such as stalagmites and stalactites. Another form taken by calcite is that of oolites (oolitic limestone) which can be recognized by its granular appearance.
(Nummulites) - were a snail type animal made up internally of small chambers arranged in a spiral.
Metaphysically Nummalitic Limestone can be used as a grounding stone, useful in communications with ancestrial spirits, assists in helping one widen knowledge, remain steadfast, reach long term goals and fucus on family oriented processes.
