Summary: The study of subsurface Middle Pleistocene deposits was
performedusing subsurface mapping methods. These sediments consist
ofunsorted gravels of lithoarenite pebbles mixed with sand andsilt. To the
west of the confluence of Krapina with Sava they areunconformable upon
Upper Pontian layers, filling up a furrow-likedepression in the
palaeorelief. These depostis form aplano-convex shaped lenticular body,
produced by the transport ofdetritus from the nearby dry land areas into a
shallow sweetwater environment.
Deposition occured during the Mindel/Riss interglacial stage, andone part
of the Riss glacial, before cooling and draught hadreached their peak. The
swamps of contemporaneous periglacialbelt were then drastically reduced in
size or dried up. Suchconditions probably persisted until the end of
Pleistocene, asthe Wuerm glacial is distinguished by the coldest, driest
weatherthroughout the Quaternary. A sudden thaw and tectonic movementsin
the Holocene enabled intensive fluvial transport anddeposition of well
graded gravels, with rounded pebbles(primarily composed of limestone),
which directly covered eitherPontian or Middle Pleistocene deposits. In
comparison with olderclastics, they represent a different mode of
sedimentation andmore distant source for the greatest mass of detritus.

Summary: West of Zagreb, within an area of 6 ha, four units
totalling 60 mthickness have been recognized on the basis of core
analysis,geological mapping, geophysical measurements in exploration
wellsand laboratory analyses. The deepest situated unit (Unit I)accumulated
during the Lower Pleistocene. It is interpreted tohave formed by
accumulation of loess mixed with local materials(loessoid). Unit II is
cosidered to be Middle Pleistocene in age.While in its lower and middle
part fluviatile-lacustrinesediments are recognozed, in the upper part
aeolian materialcontributed to the composition of the sediments. This unit
isoverlain by Unit III which is considered to be Upper Pleistoceneine age.
The composition of the unit is dominated by material ofloess origin, and is
interpreted to have formed in a marshyenvironment. The youngest unit (Unit
IV) is composed of Holocenefluviatile sediments. The upper parts of Units
I, II and IIIdisplay paleisol features indicating that they were subjected
tothe action of soil forming processes during phases of subaerialexposure.
These occured as a result of lake/marsh infilling whichhappened during the
cold and dry glacials and probably lastedduring the older periods of
interglacials. Resumption of shallowand quiet water environments during
younger periods ofinterglacials is congruous with the increased influence
ofhumidity. The formation of both, specific sedimentaryenvironments and
phases of subaerial exposure was also influencedby differently displayed
neotectonic activity which was onlypartly compensated for by sedimentation
and denudationrespectively.

Summary: Exlored outcrops and quarries of mostly gravel and sand
Pliocene to Pleistocene of age are situated in zone of southern marginal
fault of Drava river depression. Thickness of these deposits exceeds 400m.
In the sporadical interbeds of silty marls a species-rich phytocenozis of
Angiospermae has been determined. Before mentined characteristics can be
applied to longitidinal gravel bars deposited by braided streams on
alluvial fans.
