Pd/Pt IMBALANCE IN LAVAS AND INTRUSIONS OF THE NORILSK-TALNAKH ORE REGION
The paper considers the Pd/Pt ratio in the ores of the Norilsk-1 and Talnakh deposits associated with the Permian-Triassic intrusions of the Norilsk type in comparison with that in the lavas of the same age in the Norilsk region.

HIGH-PRESSURE METAMORPHIC ROCKS OF THE CHARA OPHIOLITE BELT (CAOB): AGE AND EXHUMATION CONDITIONS
A critical element in the construction of tectonic models of exhumation of basalts that have undergone high-pressure metamorphism is the diagnosis of synchronicity and the genetic relationship between deformations and high-pressure metamorphic changes ...

Dynamic evolution of changbaishan volcanism in Northeast China illuminated by machine learning
Previous studies propose that there is a mantle upwelling that generated the Cenozoic basalts in Changbaishan. However, the dominant source and mechanism of the mantle upwelling remains highly debated.
