Mineralogy and distribution of critical elements in the Sn–W–Pb–Ag–Zn Huanuni deposit, Bolivia [PDF]

open access: yes, 2019
The polymetallic Huanuni deposit, a world-class tin deposit, is part of the Bolivian tin belt. As a likely case for a “mesothermal” or transitional deposit between epithermal and porphyry Sn types (or shallow porphyry Sn), it represents a case that ...

Permafrost Thaw Dynamics Drive the Regime Shifts of Iron‐Bound Organic Carbon Sequestration in the East Siberian Arctic Shelf

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract In the changing Arctic, permafrost thaw is shifting from gradual to abrupt. Although iron‐bound organic carbon (OC‐FeR) critically modulates permafrost carbon‐climate feedbacks, its decadal‐scale variability and response to this regime shift remain poorly constrained.

Global Copper Deposit Dataset: A New Open‐Source Database for Advanced Data Analysis and Exploration Targeting

open access: yesGeoscience Data Journal, Volume 13, Issue 1, January 2026.
We build a new, open‐source global copper deposit dataset (GCDD), facilitating AI‐driven data analysis for exploration targeting and improving our understanding of copper mineralizing systems and their mappable expressions. The GCDD hosts information about 1483 copper deposits worldwide, capturing key deposit attributes such as location, genetic type ...

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

open access: yesResource 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 ...
