Evidence for Himalayan remagnetization in Tarim Basin

Himalayan remagnetization in the Tarim Basin was found to be widespread in Paleozoic, Mesozoic and Cenozoic rocks. Rock magnetism was performed to study the magnetic carriers. The authors believe that tectonic fluid in the Himalayan stage caused the rock remagnetization. The framboidal pyrites in bitumen and hydrocarbon-rich rocks may transform to framboidal magnetite in the later alkali environment, which leads to remagnetization.
