Abstract: 

The Bulgarian Early Cretaceous basin developed within the northern periphery of the Tethyan Ocean adjacent to the European fragment of the Eurasian lithospheric plate. The basin was of a back-arc type, and formed over the Moesian microplate. It had an arc configuration convex to the North. An avolcanic island arc was situated South of it. Further South, a comparatively narrow interarc basin developed that was bounded to the South by a well-expressed volcanic island arc. The midocean zone of the Tethys Ocean passed through the Aegean.

Т. Николов. Ц. Цанков. Положение болгарского раннеемелового бассейна в Теmисе. Болгарский раннемеловой бассейн развит в северной периферии Тетисского океана, в части прилежащей к Европейскому фрагменту Евразийской литосферной плиты. Бассейн – заддугового типа, и формировался на Мизийской микроплите. В общем плане, бассейн дуговидного характера, выпуклый к северу. К югу располагается авулканическая островная дуга. Еще более к югу от этой авулканической островной дуги развит сравнительно узкий внутридуговой бассейн, ограниченный с юга хорошо выраженной вулканической островной дугой. Срединнокеаническая зона Тетисского океана проходила через Егей.
