Based on studies of petrography, mineralogy and mineral chemistry, deep mantle fluids and their products in kimberlites and diamonds can be assorted into the ultradeep fluid‐transmitted minerals with an oxygen‐free feature, the deep fluid metasomatized‐minerals characterized by enrichment in TiO 2 , K 2 O, BaO, REE and Fe 3+ , and the deep fluid‐reformed minerals. The three types show a successive descent in fluid origin depth and metasomatism strength, and they have brought forth a series of corresponding metasomatic products.
