On the Lake Erie beach there are many oddly-shaped rocks called septarian concretions. Shaped and patterned similar to a tortoiseshell, naturalists in the past speculated that these oddities were dinosaur eggs and carvings by ancient humans. However, scientists have discovered that septarian concretions are mineral deposits that form around a ...The meaning of septarian comes from the Latin "septum" meaning "a dividing partition between two tissues or cavities". In anatomy "septum" is the cartilage in the nose that separates one nostril from the other. Septarian correctly known as a septarian nodule or concretion is distinctive, takes on a high polish and is classed as a rock not a ...Septarian nodules 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.

Here we present carbonate clumped-isotope, δ13C (δ13Ccarb), and δ18O (δ18Ocarb) values for septarian concretions taken from four host units in order to assess cement paragenesis and overcome traditional shortcomings. Clumped-isotope and δ18Ofluid data exhibit a wide range of values, with carbonate precipitation temperatures between ~ 20 ...Septarian Concretion. A septarian concretion is a type of concretion that contains angular cracks called "septaria." These cracks vary in shape, volume, and shrinkage. It is unclear what creates the septaria, but several mechanisms have been proposed, including the expansion of gases produced by decaying organic matter. Cannonball Concretiontions have been described from unlithi®ed Pleis- This paper reviews the basic characteristics of tocene clays (Duck, 1995). septarian concretions, especially illustrating the Septarian concretions occur in a variety of wide range of septarian crack shapes and other tectonic settings, ranging from shelves and pro- deformation features.As a contractor, accuracy is everything when it comes to estimating concrete projects. One tool that can significantly improve the precision and efficiency of your estimates is a concrete estimate calculator.The Moeraki boulders are large (to 2 m) calcite concretions with septarian veins of calcite and rare late-stage quartz and ferrous dolomite. The concretions are enclosed by Paleocene marine mudstones with vitrinite reflectance values of 0.29% R suggesting maximum burial temperatures of 25-30 degrees C. Microprobe analyses of these concretions indicate a Ca enrichment-Mg depletion trend with ...

WOSU. A round concretion about two feet in diameter sits half-buried along the creek in Shale Hollow Park. Danielsen explained that some of the biggest concretions can be found here in the Ohio Shale. "We can find them anywhere from like centimeter size, really little, to like 9 feet," Danielsen said.concretions. Septarian concretions may thus preserve a signature of basin seismicity as it relates to their cementation history. Keywords Concretions, cracks, deformation, …Septarian A concretion is a hard, compact mass of matter formed by the precipitation of mineral cement within the spaces between particles, and is found in sedimentary rock or soil. [1] Concretions are often ovoid or spherical in shape, although irregular shapes also occur. The word 'concretion' is derived from the Latin con meaning 'together' and ….

ABSTRACT: Septarian concretions exhibit multiple generations of cements that include body, fringe, and spar phases. Classic paragenetic interpretations include initial precipitation of the body followed by fringe(s) and then by spar in more or less discrete events. Traditional approaches (e.g., carbon and oxygen isotope analyses) are generally ...Significance of localized pore pressures to the genesis of septarian concretions. 1997 • Mark W Hounslow. Download Free PDF View PDF. Reworked early diagenetic concretions and the bioerosional origin of a regional discontinuity within British Jurassic marine mudstones. 1992 •This process cemented the sand grains together aided by the pressure of additional sediment deposited above. The concretions formed as the calcium ions were preferentially and chemically drawn to organic matter such as the clusters of dead clams and their shells. The organic matter formed a nucleus around which the spherical concretions could grow.

A quartz nodule, for example, contains an interior of quartz. Nodules can be concretions, which can reach many feet in diameter. These tend to be found alongside areas of erosion. Some nodules are septarian nodules, which are flatter and contain …Concretions called septarian nodules feature a pattern of radiating cracks that are divided by a pattern of concentric cracks, giving the structure a “turtle-back” look. The Septarian Nodules Meaning. The meaning of septarian nodules lies in their geological significance and cultural symbolism.
