They are abundant in Mediterranean regions, the Balkans, the Iberian Peninsula and Macaronesia, but can also be found in Central Europe and temperate Asia.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.43) In recent years Russian prospectors have found more meteorites of the Seymchan pallasite at the original find location, some of them weighing as much as several hundred kilos. Most of the material, however, is not of the pallasitic but of the sideritic phase. This is an etched fullslice showing the transition phase of the pallasitic and the ...In: Clinical hematology atlas. 5th ed. St. Louis, Missouri: Elsevier Inc.; 2017. p. 107-14.

A thin, bored sideritic horizon (about 4 cm thick) caps the facies association and separates it from the overlying Prodelta - Subaqueous Delta Platform Facies Association (FA 3) (Fig. 6 B). Another bored sideritic horizon is also present in the middle of the succession (Fig. 6 B). FA 2 is present in the cored interval of well C-2 (Fig. 6).(a and b) Sheeted like stratabound Zn-Pb±Ba mineralization in the uppermost of the Kl unit (silicified and dolomitized limestone, Klsd), best developed concordantly under the marls of the Ks unit, Robat deposit.

Additionally, we determined the partitioning of major elements in coexisting silicate and carbonate melts in perovskite-hosted melt inclusions to explain the dominance of calciocarbonatites (sövites) relative to dolomitic or sideritic types (Heinrich 1966; Tuttle and Gittins 1966; Le Bas 1977; Bell 1989).

The petrographic study shows sideritic shale with secondary porosity exists in the form of micro fractures (Figure 3B, C and D) which are filled by non-calcareous and calcareous secondary minerals. Scanning Electron Microscopic study reveals that most of the micro-pores are associated with pyrite framboids (Figure 3E and F) andBack-scattered electron microscopy has been used to examine the microstructure of nonmarine-shale-hosted siderite concretions. The concretions are composed of 50-100 micrometer, zoned crystallites, which exhibit no noticeable center-to-edge variation within any individual concretion.MRI. Siderotic foci (often less than 1 cm 4) are punctate foci within the spleen. The high magnetic susceptibility effect of hemosiderin typically renders the siderotic foci markedly hypointense on certain sequences. Hence, signal characteristics of the nodules include: T2: very low-signal.

Locally and rarely the sandstone is tightly cemented by siderite or pyrite rather than quartz, in which case the terms sideritic sandstone or pyritiferous sandstone are applied. Well-sorted porous sandstone varies greatly in hydrocarbon content, ranging from slightly oil-stained sands to sands that are partly or completely saturated with oil.KEYWORDS: plant fossils preserved within sideritic nodules, Upper Carboniferous, Sosnowiec, Coseley, Mazon Creek, FossilLagerstätten, Konservat-Lagerstätten. The paper is a survey of Pennsylvanian sideritic localities.

The phosphate is believed to be an early diagenetic replacement of carbonate concretions, probably penecontemporaneous with Ashfield Shale deposition. The U and F content of the phosphate does not support a marine origin for the formation. Where protected from compression within hard sideritic bands, the phosphatic nodules remain spheroidal. Alkali basalt, basaltic andesite, and dacite occur at the bottom of the sequence, covered by a thick suite of variously-colored, marsh–lake facies sediments, including medium- to fine-grained sandstones, siltstones, conglomerates, argillites and coal, with sideritic ironstone layers (Li, 1998, Wu et al., 2007c).Based on thin section and SEM analysis, sideritized detrital clay matrix is the predominant constituent (>50%) in the sideritic claystone and the detrital clay matrix had been extensively replaced by siderite (Fig. 17 D and 18D). Detrital quartz grains and organic fragments in the sideritic claystone were largely present in the laminae.Sideritis: [noun] a genus of European woolly mints having small flowers with the corolla included in the calyx.Bivalves: A-C: Oysters preserved in growth position preserved in sideritic sandstone matrix; found on Breezy Point, NY.
