Geology, petrology, and iron deposits of the Guiana …

Ferruginous quartzites intercalated in the Imataca feldspathic gneisses are the host rocks of extensive iron deposits (as at Cerro Bolivar) whose formation was due to oxidation of magnetite to hematite and leaching of quartz. The great size of the ore deposits is attributable to repetition of the iron-bearing beds in tight folds.

ECONOMIC GEOLOGY

ECONOMIC GEOLOGY By Preston McGrain ... Iron-bearing minerals, commonly limonite, are sometimes found at the contact of Tuscaloosa gravels and Mississippian carbonates. The iron deposits, which appear to be a bog ore developed on the pre-Cretaceous erosional unconformity, were the source of raw material for several furnaces that were …

Geology and iron ores of Steep Rock Lake [Ontario]

Abstract. Mining operations at Steep Rock Lake since 1945 have yielded about ten million tons of high-grade iron ore and have cast new light on the geology of this long-famous Precambrian area. The productive length of this most-recently discovered of the Lake Superior ranges should exceed four miles and ore intersections have been obtained at ...

Facies relations in the Gunflint iron formation [Ontario] | Economic …

Iron- and silica-bearing rocks of the Gunflint were deposited in a marginal basin that bordered open sea water in a region of volcanic activity. Volcanism played a dual role: it provided a steady source of iron- and silica-bearing solutions and induced cyclical fluctuations in the basin of deposition. This resulted in cyclical sedimentation of ...

Isotopes in Economic Geology, Metallogeny and Exploration—

Hence, iron isotopes can be used to better understand processes involved in formation of not only iron ore deposits, but also other deposits in which iron is a major component of the ores. As discussed by Mathur and Zhao ( 2023 ), much of the variability in δ 65 Cu in deposits stems from redox and other reactions, either during hypogene ore ...
