Magmatism and mineralization in the Permian large igneous province in the Tarim Basin, NW China

摘要

The Early Permian Tarim Large Igneous Province (Tarim LIP) in northwestern China, contains extensive flood basaltic lavas, interlayered with tuff and sedimentary rocks, and layered intrusive rocks.The lavas have ages of 290-285 Ma, whereas the intrusive rocks range from 284 to 2 74 Ma.Using whole-rock geochemistry and Sr-Nd-Pb-Hf-PGE isotopic data of the different magmatic rock types and the associated Fe-Ti-V oxide deposit, we present a magmatic evolutionary model for the Tarim LIP genetically relating it to mantle plume activity and discuss the genesis of the Wajilitag Fe-Ti-V oxide deposit.
