NEW DATA ON THE STRUCTURE AND SEISMOSTRAT IGRAPHY OF DANUBE FAN

Detailed high frequency seismoprofiling was performed in the axis zone of the Danube cone during an international expedition on board of R/V ''Gelendzhik'' in 1993. Five hurried accumulative swells (suprafans) were distinguished in some seismoprofiles crossing the central part of the cone. They overlay each other in a strict succession with a stron g angle of disconfirmity. They were formed during five cycles of sedim entation corresponding to the last five regression-transgression cycle s beginning from Mindel regression. The main part of sedimentary bodie s were accumaled during Mindel, Lower and Upper Riss, as well as Lower and Upper Wurm regressions. The studied section of Danube cone was fo rmed approximately during recent 0.5 my.
