Sideritic
In contrast, increased delivery of detrital iron (oxyhydr)oxides precipitates P to the sediment and initially forms sideritic beds, whereas vivianite formation initiates under slow kinetics deeper in the sediment than for siderite (Postma, 1981), as demonstrated by the incorporation of siderite, millerite and clay minerals in the vivianites ...the sideritic-kaolinitic beds ("Mánfa Siderite") found in the Central Mecsek Moun-tains. In both cases volcanic origin and a Middle Triassic age of these formations were inferred (Wéber 1965, 1978; Nagy and Ravasz-Baranyai 1968); however, these interpretations were not supported by unequivocal analytical results. Despite this,

It may also occur as black-band ore, which can form extensive stratified beds admixed with shales, other carbonates, and coal.

13.6.5.4 Sideroblastic Anemia. Sideroblastic anemia is characterized by a pattern of morphological marrow abnormalities in which there is an accumulation of perinuclear granules in nucleated red blood cell precursors. These granules, referred to as siderotic granules, are a result of disordered hemoglobin synthesis.Sideritic Band (Ironstone) is located in the dark gray thin-bedded shale of the Horokabetsu Formation in the Ishikari Coal Field (Palaeogene-Tertiary in age), Hokkaido, Japan.Location. About 70% of the tumors affect the subcutaneous fatty tissue and the skin, and approximately 30% involve the deep soft tissues underneath the superficial fascia. Most giant cell tumors of soft tissue are located in the upper and lower limbs and a lesser number are situated in the trunk or the head and neck area 1 .Carbonaceous sediments and rocks. Carbonaceous sediments and rocks, primarily coal, have been classified in two ways: by rank (content of carbon and caloric value) and by petrographic characteristics. In order of increasing rank, the classes of coal are (1) lignite; (2) subbituminous coal; (3) bituminous coal; and (4) anthracite.
The examination of the mineralogy of the Wealden ironstones confirms the presence of early diagenetic siderites. The trace-element assemblage shows that the sideritic ironstones are chemically pure pointing to a freshwater origin. The sideritic ironstones reveal anoxic conditions and palaeo-salinity in the basin.The early Eocene Naredi Formation in the southwestern Kutch represents the initial marine sedimentation in Kutch area during Tertiary period.

A fresh look at sideritic "coprolites" Adolf Seilacher, Cynthia Marshall,* H. Catherine W. Skinner, and Takanobu Tsuihiji Abstract. —Sideritic "coprolites" from the late Miocene of southwest Washington, the Upper Cre taceous of Saskatchewan and Madagascar, and the Permian of China have often been claimed to be pseudofossils.A sideritic meteorite, hexahedrite, Ni-poor, Type: IIAB. Found 1837; 2.1 tons. While numerous fragments have been reported since the original discovery, they are in the main — according to Buchwald — apparent components of an original single kamacite crystal. In addition to the dominant Fe-Ni metal, sectioning reveals troilite-daubréelite ...
The occurrence of root traces was common in these deposits. Flood plain, back bank lake, and swamp were also found in the flood basin facies, which were dominated by siltstones, mudstones, coal seams with ripple marks, ripple laminations, horizontal laminations, rootlets, and common sideritic concretions (No. 17, 18 and 19 in Table 1). 4.3.This paper describes the mineral changes associated with the thermal demagnetization of sideritic jasper mesobandsin the ~3.25 Ga Manzimnyame Iron Formation Bed of the Fig Tree Group in the ...The formation underlying the SSF is the Redcar Mudstone Formation (RMF) that comprises grey, silty, calcareous, and sideritic mudstone with thin shelly limestones (Powell, 1984, Powell, 2010). The DF represents a potential aquifer above the WMF. Hydrogeological characterisation of the WMF and SSF is very complex as a result of …
