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).

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.

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

Tectonic Systems and the Deposition of Iron-Formation
Precambrian Research, 1983Abstract The iron-formation group of chemically precipitated cherty iron-rich sediments ranges in age from Early Precambrian to Recent and is composed of a variety of lithological facies. Iron-formations are classified as Lake Superior and Algoma types to emphasize the contrasting conditions in the spectrum of sedimentary-tectonic environments in ...
