y Oroszlány (0-2274) (Figs 3 and 7) This sequence is a good representative of six similar borehole sequences studied in the Oros

zlány-Pus

ztavám district. The subsidence curves differ markedly from those of the southwestern area. It is to be noted that the uncertainties are much greater here. Dasycladeceae are missing, therefore only the other two "markers" have been used. The measurement of time is not precise but it is sure that the whole time-span concerned was very short, not longer than a NummulitesZone or a nannoplankton-zone. Taking it in all, we must suppose a very rapid increase in water-depth and in subsidence. il II I I I 1 ' 2 « 3 « 4 I 5 ? Ma +
