Thermodynamic Modeling of Lithium Enrichment During Partial Melting: The Importance of Partition Coefficients

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Predicting the partial melting conditions that generate Li‐rich peraluminous melts is of major economic and societal importance. However, existing models disagree on the optimal conditions (e.g., pressure, temperature, protolith) and, consequently, on targets for exploration.

Trace Element Distribution in Magnetite Separates of Varying Origin: Genetic and Exploration Significance

open access: yes, 2019
Magnetite is a widespread mineral, as disseminated or massive ore. Representative magnetite samples separated from various geotectonic settings and rock-types, such as calc-alkaline and ophiolitic rocks, porphyry-Cu deposit, skarn-type, ultramafic lavas,

Matter-mineral characteristics of technogene placers – potential sources of precious metals (on the example of the Nizhneselemdzhinsky gold-bearing node of Priamurye, Russia)

open access: yesGeoresursy, 2019
Over tens of years of mining and processing of ores and placers of gold in the world a huge amount of wastes originated in the form of spoil heaps and tailing dumps, in which the content of valuable components allow them to be considered a real ...

New Terrestrial Native Iron Discovered on Earth's Surface

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Native iron is a major common mineral in lunar samples and meteorites but rarely occurs on Earth's surface, as its stability requires highly reducing conditions with very low oxygen fugacity. To date, native iron has mainly been found in basalts, ophiolites, and deep hydrothermal systems.

Temporal relations between mineral deposits and global tectonic cycles [PDF]

open access: yes, 2013
Natural Environment Research Council (grant NE/J021822/1) supported this research.Mineral deposits are heterogeneously distributed in both space and time, with variations reflecting tectonic setting, evolving environmental conditions, as in the ...

Origin of high-Ti magnetite in magmatic-hydrothermal systems: evidence from iron oxide-apatite (IOA) deposits of eastern China

open access: yes, 2022
Magnetite chemistry has been widely used to distinguish igneous versus hydrothermal origins for a range of magnetite-bearing mineral deposits. However, the origin of Ti-rich magnetite with ilmenite lamellae from iron oxide-apatite (IOA) deposits and ...

Understanding viscous magnetization of multidomain magnetite [PDF]

open access: yes, 2006
Viscous magnetization (VM) and viscous remanent magnetization (VRM) have been measured, as a function of temperature, between room temperature and the Curie temperature using a suite of well-characterized synthetic and natural multidomain (MD) magnetite ...

The trace-element compositions of amphibole, magnetite and ilmenite as potential exploration guides to metamorphosed Proterozoic Cu–Zn±Pb±Au±Ag volcanogenic massive sulfide deposits in Colorado, USA [PDF]

open access: yes
Orthoamphibole, clinoamphibole and magnetite are common minerals in altered rocks associated spatially with Palaeoproterozoic volcanogenic massive sulfide (VMS) deposits in Colorado, USA and metamorphosed to the amphibolite facies.
