Abstract

In Permo-Triassic Eurasia two transcontinental mantle events can be recognized: • the c. 295-280 Ma Tarim event, between western Europe and eastern Kazakhstan (c. 8,500 km apart) and • the c. 250-245 Ma Siberia event, between western Europe and northeastern Asia (c. 10,000 km apart). Were these events driven by deep mantle plumes, shallow mantle processes, or both, or something else
