Iron deposits in the precambrian iron-ore formations
Vestnik of North-Eastern Federal University. Series "Earth Sciences", 2023Аннотация. В статье приводится краткая информация о распространении железорудной формации на континентах, с которой связаны крупнейшие месторождения железных руд. Указывается, что значимым компонентом железистых кварцитов многих месторождений мира, а также сформировавшихся за их счет залежей богатых железных руд других формаций являются благородные ...

Iron is stored within the liver, spleen, and other organs of the reticuloendothelial system. Iron overload can occur as a result of primary hemochromatosis, cirrhosis, anemia, and multiple transfusions. PET/MR imaging has the ability to use multiple MRI sequences to detect and confirm liver iron deposition.

Photoemission study of iron deposited on fullerenes
Physical Review B, 1994Photoelectron spectroscopy is used to study iron particles grown by depositing Fe on a fullerene film. For small amounts of iron deposited on the fullerenes, the Fe 3p core level is shifted \ensuremath{\sim}0.4 eV to greater binding energy and a clear Fermi edge is missing.

Tissue Affinity as a Factor in Iron Deposition
Nature, 1964VARIOUS factors are known to influence the absorption of iron from the gastrointestinal tract. From work performed in our laboratory it would appear that an additional factor, not considered previously, is an alteration in the tissues, so that there is an increase in the affinity of the liver for iron.

GEOCHEMISTRY Banded iron formations (BIFs) are enigmatic, yet stunning, sedimentary rocks deposited mainly in the Late Archean to Early Proterozoic (2.7 to 1.9 billion years ago). They consist of micrometer- to centimeter-wide alternating layers of iron-rich and silica-rich material.

Abstract Iron ore deposits are widespread throughout the Circum Pacific (Park, 1972). However significant production has been confined to three areas: the south-east China province from Hainan island through Kwangtung and Fukien, the Malay Peninsula and the Philippines (Fig. 9.1).

Iron Deposition in the Corneal Graft
Archives of Ophthalmology, 1983Linear iron deposits in the corneal epithelium are well-documented phenomena in a variety of circumstances, both normal and pathologic. A characteristic annular pigmented line, appearing clinically as an "iron" line, occurred in the donor epithelium of approximately 13% of corneal grafts with retained sutures. Eight cases of normally functioning grafts
