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 ...

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.

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.
