Abstract
The paper presents a unique geodynamic evolution concept of all processes and structures ensuring carbon source formation and movement for diamond crystals growth in the mantle, and diamondiferous medium supply to the surface. Geodynamic basis for diamond formation is exogenetic source sinking in old subduction zones evolving along convection cell edges. The supply is ongoing in an advection system, with transtension combined with convection playing a key role. The paper shows periods of spatial pipe cluster location and tectonophysical pattern of this phenomenon. Based on geodynamics, the authors suggest improving a taxonomical scheme of the diamondiferous system due to its fractal structure, from a mineragenic province to a pipe cluster. Specific examples are presented to highlight major structural elements of diamondiferous taxons (systems) and their formation patterns. Debatable issues of kimberlite nature are discussed.
