Abstract: 

The evolution of the ideas about the basement complexes on the Balkan Peninsula has developed from the initial attribution to a single and uniform Precambrian complex towards differentiation, and recognition of different protoliths that underwent polymetamorphic and multideformational histories. Correlation between metamorphic complexes distinguished in different Alpine and/or Hercynian tectonic zones should be made only when a detailed knowledge were obtained on all significant features of the protoliths and the superimposed metamorphic and structural events. The now available petrologic information is still insufficient to fully understand and outline the complex 3D history of the region.

И. Загорчев. Метаморфические комплексы амфиболитовой фации в Болгарии и пре камбрийская геодинамика: противоречия и состояние вещей. Эволюция идей о комплексах фундамента на Балканском полуострове развивалась из начальной концепции о единном и единственном прекамбрийском комплексе к диффенциации и признании разных протолитов которые перетерпели полиметаморфическую и полидеформационную историю. Кореляцию между метаморфическими комплексами обнаруженными в отдельных альпийски и/или герцински тектонических зонах надо делать только когда была бы получена детальная характеристика все основных оссобеностей протолитов и наложенных метаморфических и деформационных событий. Настоящая петрологическая информация недостаточна чтобы полно понять и обрисовать комплексную тридименсионную историю региона.
