Micron-scale d13C determination by NanoSIMS in a Juina diamond with a carbonate inclusion
sub-lithospheric diamonds Juina carbonate lower mantle peridotite eclogite
2017/4/10
Juina diamonds present a wide spectrum of mineral inclusions, covering both peridotitic and eclogitic composition.
Among the most rare inclusions, carbonates are interpreted as an evidence of deep re...
The role of mineral surfaces in the preservation and transformation of organic carbon: meso- to nano– scale spatial complexity of organic matter forms in organic-rich shales
