Breed Associations of the Gaisin Block of the Ukrainian Shield [PDF]
Geochemistry and ore formation, 2021 The Gaysins block is characterized by a wide range of both metamorphic and ultrametamorphic formations. Ultrametamorphic formations are represented by an association of rocks with a transition from charnockitoids to two-feldspar granites. Remnants of metamorphic rocks are composed of diafluorinated varieties to varying degrees.
