Mineralography, paragenesis sequence, and sulfur isotopic composition of Baba-Ali and Galali iron ore deposits from the Sanandaj-Sirjan zone, northwest Iran

Journal of Economic Geology
The northern part of the Sanandaj-Sirjan zone hosts important iron deposits formed during the Mesozoic magmatism. The Baba-Ali and Galali ore deposits occurred on the border of Hamedan, Kermanshah, and Kurdistan provinces.

Occurrence and Geochemistry of REE Minerals From the Western Part of the Lugiin Gol Carbonatite Deposit, Southeast Mongolia

Resource Geology, Volume 76, Issue 1, January‐December 2026.
The western Lugiin Gol REE deposit, related to the Lugiin Gol alkali intrusive complex, consists of carbonatites filling NE‐trending fractures in sedimentary rock. The carbonatites are dominated by carbonate minerals and fluorite and host REE fluorocarbonates, including synchysite‐(Ce), bastnaesite‐(Ce), parisite‐(Ce), and synchysite–bastnaesite ...

Hematite Formation During Skarn Mineralization in the Akatani Iron Deposit, Niigata Prefecture, Japan

Resource Geology, Volume 76, Issue 1, January‐December 2026.
The Akatani Fe deposit in NE Japan has been regarded as a skarn deposit because iron‐oxide ores occur within marble‐hosted skarn near the Cretaceous Ninoujidake granite. U–Pb dating of fluorapatite in the skarn indicates that this skarn formed in the Late Cretaceous, contemporaneous with the granite.

The scheelite-skarn of Salanfe (Valais, Switzerland)

, 1993
New data on geology, metamorphism, mineralogy and formation mechanisms of the scheelite-skarn of Salanfe are presented. The skarn, situated in a metasedimentary sequence of possible Pre-Cambrian age in the Aiguilles Rouges massif (Swiss Alps), was formed

Characterization and Formation Process of Phayaung Taung Mesothermal Gold Deposit, Central Myanmar: Constraints From Raman Analysis of CO2 Bearing Fluid Inclusions

Resource Geology, Volume 76, Issue 1, January‐December 2026.
This study characterizes CO2‐bearing fluid inclusions in quartz from the Phayaung Taung mesothermal gold deposit, central Myanmar, using Raman spectroscopy. The results provide constraints on fluid composition, CO2 density, and possible formation conditions, indicating the involvement of low‐salinity H2O–CO2 fluids during gold mineralization.

Geology, Sulfur Isotopes and Ore Fluids of the Meyon Gold Deposit, Mon State, Southern Myanmar: Implications for Orogenic Gold Mineralization

Resource Geology, Volume 76, Issue 1, January‐December 2026.
Sulfur isotope compositions of pyrite (δ34S = −2.80‰ to +4.43‰) cluster near 0‰, indicating a dominantly magmatic–metamorphic source. Fluid inclusion assemblages record a systematic evolution from CO2‐rich to mixed CO2‐H2O and subsequently to H2O‐dominant fluids.

Research Progress and Typical Cases of Deep Mines Backfill Technology in China

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
With the increasing depletion of shallow mineral resources and the growing demand for metals, deep mining has become a strategic focus for China. However, deep mining operations face a series of complex challenges, including high ground stress, elevated geothermal gradients, and severe rockburst hazards.

Evaluation of the Homogeneity of Geochemical Reference Materials by Wavelength‐Dispersive X‐Ray Fluorescence Spectrometry Using 0.1 g Fusion Samples

Journal of Chemistry, Volume 2026, Issue 1, 2026.
Good homogeneity is a critical guarantee for the accuracy of certified reference material values. X‐ray fluorescence spectrometry (XRF) is widely used for the homogeneity testing of geochemical reference materials due to its simple sample preparation and high analytical precision.

Skarn-porphyry transition: an example from the Antamina skarn, Peru

, 2015
It is important to understand skarn-porphyry transitions in order to use exposed skarns to look for associated and potentially larger porphyries. For such purposes, a good start is to understand the transition between porphyry and skarn in known deposits.
