Ancient craton geology creates conditions for kimberlite pipes containing economic diamond deposits
the verdict
SUPPORTED
the evidence backs this
confidence 87/100
Multiple geological and geochemical studies support the connection between ancient cratonic lithosphere architecture, deep mantle metasomatism, and the generation and preservation of diamond-bearing kimberlite pipes.
