Carbonate alteration of ophiolitic rocks in the Arabian–Nubian Shield of Egypt: sources and compositions of the carbonating fluid and implications for the formation of Au deposits [PDF]

, 2016
Ultramafic portions of ophiolitic fragments in the Arabian–Nubian Shield (ANS) show pervasive carbonate alteration forming various degrees of carbonated serpentinites and listvenitic rocks.

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

Geophysical 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.

Inversion of the physical properties of seafloor surface sediments based on AUV sub-bottom profile data in the northern slope of the South China Sea

Scientific Reports, 2021
Based on the seafloor reflection coefficient obtained from autonomous underwater vehicle (AUV) sub-bottom profile survey data of the northern slope of the South China Sea, combined with the sample test data of seafloor surface sediments, we use the Biot ...

Metallogeny of Greenland

Ore Geology Reviews, 2016
Abstract Greenland is the largest island on Earth, with 80% of its area covered by a thick ice sheet. The coastal areas are underlain by variable rocks ranging from Eoarchean to the most recent ages. Greenland has a mineral exploration tradition since its colonization in the 18th century, and mining of cryolite started in 1854.

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

Geoscience 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 ...

Fragment of a central-type large structure located in southern Uganda and its metallogenic value

Известия высших учебных заведений: Геология и разведка, 2020
For the southern regions of Uganda, the metallogenic value of the regional arc belt of dikes of the main and ultrabasic composition was considered. It is shown that it is part of the arc sector of a large central-type structure with a diameter of about ...

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 ...

Gold metallogeny of Southern Mongolia

Руды и металлы
Within the Southern Mongolia, the South Gobi gold ore belt stretching in the sublatitudinal direction for almost 1000 km is the most promising in terms of ore gold. Several gold ore regions are distinguished within its boundaries, the most significant of
