EPSL: Slab-mantle interaction, carbon transport, and kimberlite generation in the deep upper mantle

  By Chenguang Sun and Rajdeep Dasgupta   Abstract: Low-degree partial melts from deeply subducted, carbonated ocean crust are carbonatite liquids with ∼35–47 wt% CO2. Their reactions with the overlying mantle regulate the slab–mantle interaction and carbon transport in the deep upper mantle but have not been investigated systematically. Here we present new multi-anvil experiments […]
