    • Carbon cycling during the India-Asia collision revealed by δ26Mg–δ66Zn–δ98Mo evidence from ultrapotassic volcanoes in NW Tibet 

      Wang, Jian; Tappe, Sebastian; Wang, Qiang; Li, Jie; Zou, Zongqi; Tang, Gong-Jian (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-06-18)
      India-Asia continental collision–induced volcanic gas emissions are thought to have played an important role in driving Cenozoic atmospheric CO<sub>2</sub> variations, yet the details of how the deep carbon cycle may influence volcanic CO<sub>2</sub> degassing are not understood. We present a novel study employing Mg-Zn-Mo isotopic compositions of Cenozoic ultrapotassic lavas from NW Tibet. The ...

    • Tracing Subducted Carbonates in Earth's Mantle Using Zinc and Molybdenum Isotopes 

      Wang, Jian; Tang, Gong-Jian; Tappe, Sebastian; Li, Jie; Zou, Zongqi; Wang, Qiang; Su, Yu-Ping; Zheng, Jian-Ping (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-02-23)
      Although carbonates are the primary form of carbon subducted into the mantle, their fate during recycling is debated. Here we report the first coupled high-precision Zn and Mo isotope data for Cenozoic intraplate basalts from western China. The exceptionally high δ<sup>66</sup>Zn values (+0.39 to +0.50‰) of these lavas require involvement of recycled carbonates in the mantle source. Variable ...
