The birth of the Sava Suture Zone: The early geological observations and the context of bimodal magmatism (southern Belgrade outskirts; Andjelkovic, 1973)

This paper presents one of the significant results research Prof. Dr. Milodrag Andjelkovic. The study underlines first field record providing evidence Upper Cretaceous bimodal magmatism that eventually led towards definition Late ?Sava?Vardar Zone? in 2002 (Pamic, 2002). Currently, 20-years old i.e., Sava Suture Zone regarded as a crustal assembly formerly intervening amalgamated Adria and south Eurasian affinities. pioneering mapping- based observations contributing debuted Zone, are underestimated report Andjelkovic, presenting his typifying (published 1973 regional XIX-century established journal ?Annales geologiques de la peninsule Balkanique?; Title: ?Geologija mezozoika okoline Beograda?, translated: geology Mesozoic assembly: vicinity Belgrade area). time, during early 1970?s, entire geoscience community former Yugoslavia for long time denying any within Vardar offering counterargument grounded onto geosyncline tectonic framework. was published much prior constraints on magmatic intrusions, discussed ?Peri Adriatic arc? or Peri Lineament, but only three decades later.
