  1. A study of mantle inclusions in the Koffiefontein Kimberlite Pipe, South Africa by Cardoso, P

    Published 2016
    “…A small number of concentrate grains have compositions matched by the diamond inclusions. Attempts to apply geothermobarometry to the pyroxenites and to the diamond inclusions gave conflicting results which are ascribed to lack of equilibration between co-existing mineral phases and/or within individual mineral grains. …”

  3. An investigation of the possible correlations between kimberlite lithophases and their indicator mineral compositions at Finsch Diamond Mine, Northern Cape Province, South Africa by Thunsi, Karabo

    Published 2026
    “…A significant proportion of the sampled KIM have compositions associated with diamonds (e.g., such as G10 garnets or with compositions overlapping with Finsch diamond inclusions) and pressure and temperature values lying within the diamond stability field. …”

  4. The petrogenesis and geochemistry of the Namaqualand olivine melilitite pipe cluster, western South Africa by Kirchner, Michael

    Published 2023
    “…Oxygen isotope ratios of olivine separates indicate that olivines from a large majority of the melilitite pipes have compositions indistinguishable from those from typical upper mantle peridotite (4.9-5.2‰). …”

  5. Petrology and geochemistry of the diamondiferous K-richteriteand leucite-bearing Kareevlei Kaapvaal lamproite by Qashani, Zuko

    Published 2024
    “…The phlogopite rims have compositions similar to typical Kaapvaal lamproites and represent direct crystallization by the parent magma. …”
