Overview

Randomized trial reveals distinct isotopic compositions in pyroxenite veins, highlighting mantle diversity.

Key Points

  • This research investigates the isotopic diversity of mantle-derived melts preserved in pyroxenite veins.
  • Analyzed Nd–Hf isotopic data for bulk rock, clinopyroxene, and orthopyroxene from pyroxenite veins.
  • Samples were collected from mantle massifs along the Yarlung‐Tsangpo Suture Zone in southern Tibet.
  • Compared isotopic compositions of clinopyroxene and orthopyroxene to assess melt pulse diversity.
  • Clinopyroxene and orthopyroxene displayed distinct initial isotopic compositions, indicating different melt origins.
  • Orthopyroxene recorded enriched and less radiogenic signatures compared to clinopyroxene, suggesting better preservation of enriched melt components.
  • Pyroxenite veins showed a range of initial Nd–Hf isotopic compositions extending beyond values reported for basaltic lavas.
