Protogenetic sulfide inclusions in diamonds date the diamond formation event using Re-Os isotopes [PDF]

Geology, 2021
Sulfides are the most abundant inclusions in diamonds and a key tool for dating diamond formation via Re-Os isotopic analyses. The manner in which fluids invade the continental lithospheric mantle and the time scale at which they equilibrate with preexisting (protogenetic) sulfides are poorly understood yet essential factors to understanding diamond ...
