As bits of the keel’s carbonate- and water-rich rocks mix into the churning mantle, they could melt just enough to form an effervescent magma similar to kimberlites that would hurtle to the surface. The processes that control the different modes of coherent kimberlite emplacement remain uncertain. Compared to surface mining, underground mining is expensive and dangerous. Similar to gold mining, diamonds can be separated from weathered kimberlite, known as yellow ground. Large volumes of an olivine-rich rock type called peridotite occur at great depths in the earth in a layer called the mantle. The North Atlantic craton in West Greenland and northern Labrador has been subjected to deep volatile-rich melting events between ca.
