prints digital prints giclée. Looks somewhat like a fossil turtle shell, but this is a specimen known as a septarian concretion; natural formations of rock, usually a carbonate mudstone, with veins of crystalline minerals, usually calcite (basically cracks in dried mud which have eventually infilled with precipitating minerals).The specimen was originally discovered in a large septarian concretion by amateur rock collectors. Judging from the abundance of large bone fragments that we found in the debris yesterday, the concretion was broken apart haphazardly in an attempt to recover the remains, which reportedly included a partial skull, limb bones and ribs. ...Septarian Nodule is a fascinating sedimentary rock that was formed during the time of the dinosaurs. It is a combination of several minerals, including Aragonite, Barite, Betonite and Calcite. The most famous specimens come from Madagascar and Utah, USA. Both deposits look very similar with a vivid yellow entwined with grey and brown.septarian nodule A concretion, roughly spheroidal in shape, usually of clay ironstone, and characterized by an internal structure of angular blocks separated by radiating mineral-filled blocks.The mineral filling the cracks is usually calcite.The structure results from the formation of a hard exterior to the nodule due to the development of an aluminous gel on the exterior, followed by ...Septarian nodules formed as a result of volcanic eruptions and compressed matter of Dead Sea creatures. 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!Iron-oxide nodules or concretions are the most common kind of meteorwrong sent to us. Hematite and magnetite are two common iron-oxide minerals. Most iron ore deposits consist mainly of hematite, magnetite, or both. Iron-oxide concretions, iron-oxide nodules, and ironstones are often mistaken for meteorites because they are heavy (dense) and their unusual (frequently bizarre!) shapes catch ...Organic-rich, shale-hosted septarian and nonseptarian calcite concretions, in the Middle Devonian (Givetian) Hamilton Group of central New York State, formed early in the shallow subsurface as indicated by detailed petrography, SEM, X-radiographic, lithologic, geochemical, and isotopic analyses. delta 13 C carb values suggest that carbon was derived from microbial breakdown of organic matter ...What Is a Septarian Concretion? The septaria are the calcite filled cracks at the centre of the rock, indicating where the centres of the concretions have shrunk, possibly during dehydration during its long transformative journey. Septaria usually contain crystals, frequently calcite, that precipitated from circulating solutions.The concretion may also display a septarian pattern, or it may contain golden barite crystals in the cavities. Other marine fossils, notably ammonites, are found in large concretions in the Eagle Ford shale of the Cretaceous period exposed and quarried around Dallas, Texas.What Is a Septarian Concretion?
