Overview

Randomized trial investigates the genesis of biotite monzogranite, indicating low mineralization potential.

Key Points

  • The study aims to constrain the timing, origin, and metallogenic potential of the Penggongmiao biotite monzogranite.
  • Analysis of whole-rock geochemistry and zircon U–Pb dating.
  • Measurement of Sr–Nd–Hf isotopic compositions.
  • Characterization of mineralogical and geochemical signatures.
  • Zircon U–Pb dating reveals an age of 451.6 ± 1.5 Ma, indicating Late Ordovician emplacement.
  • Geochemical signatures suggest S-type granite derived from Proterozoic metasedimentary crust.
  • Limited potential for mineralization due to low W-Sn contents and low oxygen fugacity.
