Geology and geochemistry-based metallogenic exploration model for the eastern Tethys Himalayan metallogenic belt, Tibet

The Tethyan Himalaya is the fourth metallogenic belt discovered to date within Tibetan Plateau and contains chromite, gold Sb–polymetallic mineralization. records a series of complex tectonic–magmatic events that include break-up, subduction, collision, detachment, obduction Eastern Gondwana continent, all which generated ideal conditions for ore formation. However, this area remains under-explored, with only limited knowledge deposit types present in their relationship tectonic magmatic events. This has hampered mineral exploration region. study uses previous research region, combined mineralization adjacent regions, suggest presence three main (ophiolitic orogenic Au, hydrothermal vein deposits), highlights potential host as yet undiscovered island arc-type porphyry Cu–Au leucogranite-related Sn–(Be) summaries between evolution magmatism region mineralization, establishing temporal spatial framework eastern Tethys Himalayan belt.
