The chemistry of hydrothermal magnetite: A review

TL;DR: The most important factors that govern compositional variations in hydrothermal magnetite are (A) temperature, (B) fluid composition, (C) oxygen and sulfur fugacity, (D) silicate and sulfide activity, (E) host rock buffering, (F) reequilibration processes, and (G) intrinsic crystallographic controls such as ionic radius and charge balance as mentioned in this paper.

Petrology and Fe-Ti oxide reequilibration of the 1991 Mount Unzen mixed magma

TL;DR: In this paper, a mixture of phenocryst-rich rhyodacite and an aphyric mafic magma, was erupted during the recent 1991-1995 Mount Unzen eruptive cycle, revealing additional details about conditions in the premixing and postmixing magmas and the nature of the mixing process.

Origin of Fe–Ti Oxide Ores in Mafic Intrusions: Evidence from the Panzhihua Intrusion, SW China

TL;DR: In this article, the primary oxide, reconstructed from compositions oftitanomagnetite in the oresand associated intergrowths, is an alumi-nous titanomagnetic oxides.

Geochemistry of Magnetite from Hydrothermal Ore Deposits and Host Rocks of the Mesoproterozoic Belt Supergroup, United States

TL;DR: In this article, the authors used electron microprobe analysis (EMPA), laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) analysis, and oxygen isotope analysis to test whether magnetite from the five following geologic settings in western Montana and northern Idaho has distinct geochemical signatures: (1) greenschist facies burial metamorphic rocks of the Middle Proterozoic Belt Supergroup, (2) sediment-hosted stratiform Cu-Ag deposits (Spar Lake and Rock Creek) in Belt Super

Magnetic petrology of igneous intrusions: implications for exploration and magnetic interpretation

TL;DR: In this article, the relationship between chemistry, mineralogy and metallogenic associations of igneous intrusions and their magnetic properties is discussed, and the implications for interpretation of magnetic anomalies associated with igneous intrusion and recognition of magnetic signatures of potential intrusive-related ore deposits are adduced.
