These have evenly distributed microdiamonds that clearly show no indication of transportation by magma.
Populations of diamonds from different sources have distributions of δ13C that range markedly. Peridotitic diamonds are primarily within The everyday mantle selection; eclogitic diamonds have values from -forty to +three, although the peak from the distribution is within the mantle selection.
