We measured Fe isotopic compositions of mineral separates of harzburgite,dunite and chromitite from Luobusa,Tibet as well as two harzburgites from Zedang for comparison to constrain the origin of podiform chromite deposits.The olivine(Ol)and orthopyroxene(Opx)of harzburgites from both localities have δ~(56) Fe values of

We measured Fe isotopic compositions of mineral separates of harzburgite, dunite and chromitite from Luobusa, Tibet as well as two harzburgites from Zedang for comparison to constrain the origin of podiform chromite deposits. The olivine (Ol) and orthopyroxene (Opx) of harzburgites from both localities have δ ~ (56) Fe values ​​of
