【 摘 要 】

Four facies were distinguished within the Ivanić Grad Formation of

the Sava Depression: massive marl facies (F1), thick-bedded to massive

sandstone facies (F2), thin-bedded sandstone facies (F3) and thinbedded

sandstone, siltite and marl facies (F4). Interpretation of the

depositional mechanisms confirmed the presence of two basic sedimentary

processes. Hemipelagic deposits are represented by finegrained

detritus. The lithification of these produced a massive marl

(facies - F1). Sand detritus was transported into the depression by turbidite

currents (facies - F2- F4), and formed a narrow elongated sedimentary

body.

By comparing the facies defined on the basis of core samples, the

spontaneous-potential curve (SP) and the resistivity curve (Ra) of

identical intervals, four facies associations were defined on well log

diagrams: channel filling (FA), depositional lobe (FB), lateral and distal

turbidites (FC) and massive marls (FD).
