On the criteria of identifying the hypabyssal dyke formations and their subdivision into complexes in postfolding volcano-plutonic belts

On the example of one of the volcanic-plutonic belt the features (structural-geological, morphological, petrographic, chemical, etc.) of the hypabyssal dyke complexes in the magmatogenic ring structures formed at various stages of this belt development are discussed. The combination of these features can be the basis for identifying hypabyssal autonomous formations and subdividing them into petrographic units in regions with a similar history of development.

Keywords: hypabyssal dyke complexes, magmatogenic ring structures, volcanic-plutonic belts, criteria of magmatic formations subdivision.
