Septarian nodules are a type of concretion where mudstone of some kind is interspersed with calcite or another carbonate-rich mineral. The calcite portions follow the pattern of radiating cracks, which occur during the unique creation of these formations. Septarian nodules consist of at least two minerals in every case.Ancient mudrocks contain carbonate concretions more or less abundantly (e. g. , šRÁMEK 1978). There is strong evidence that a considerable proportion of the ancient carbonate concretions were formedWelcome to our Septarian Concretion page! Septarians were formed approximately 110 million years ago when the Gulf of Mexico reached what is now southern Utah. Decomposing sea (shell) life, killed by volcanic actions had a chemical attraction for the sediment around them, forming mud balls. Tide and wave action rolled the balls around ...The septarian concretions show a long and complex history, with early initiation of growth and development spanning several phases of burial, each often resulting in the formation of septaria. Growth apparently ceased in the transitional zone between the sulphate-reduction and the methanogenesis zones. Very early growth in the Fe-reduction ...Hall Beds, Lichfield. Body of concretion stippled, calcite filled septarian cracks white. Member (Robinson, 1996). Small septarian concretions occur in the siltstones on the road between Freemans Hall and the village of Stettin. These regularly oblate concretions are up to 14.5 cm in diameter and 7.5 cm in thickness.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.

One particular type, called a septarian concretion or septarian nodule, contains numerous angular cracks that form a network, usually in a contrasting colour.Concretions from Upper Cambrian sediments in South Wales can be divided into two groups of different ages. An early group (type) are characterised by the association of septarian structures and deformed laminae; whilst later (type Ha) concretions developed both cone-in-cone structures and parallel laminae.Determinations of the cement content …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.Concretions in Kansas are formed from any of a number of minerals, including calcite, limonite, barite, pyrite, and silica. They vary widely in shape and size, with the huge spherical concretions at Rock City in Ottawa County and Mushroom Rock State Park in Ellsworth County measuring up to 27 feet in diameter. Septarian concretionsSeptarian calcareous concretions have been observed below several major discontinuities (D7 in Hameima, D9 in Bou el Haneche, Fig. 4; D6 in El Goussa) (Fig. 10a, b).

The London Clay consists of a stiff, bluish coloured clay which becomes brown when weathered. Nodular lumps of pyrite and crystals of selenite frequently occur within the London Clay, and large septarian concretions are also common. These concretions have been used in the past for the manufacturing of cement, were once dug for this …

Therefore, the bonds of Septarian nodules are formed in sediment through the “concretion” of mud masses and mixed organic material. Septarian nodules originate from the Cretaceous period and formed anywhere between 50 to 70 million years ago! Micritic limestones form part of cyclic alternations of limestones- marls/shales in many offshore facies of epeiric seas and their origin has been, and still is, subject to controversy.
