THE MEDITERRANEAN LOWER CRETACEOUS

Albian included. The section of the series ends with calcareous breccias dated to the
Middle and Upper Albian, which pass into the Cenomanian.
The flysch sediments overlie a volcanogenic-sedimentary formation of the
ophiolite group with Upper Jurassic radiolarites in the uppermost part (В I a nche
t et al., 1972).
15.3. Kosovo
Only Barremian, Aptian and Albian sediments are known in Kosovo, developed
in the Kukes zone, in Metohia, Crnolevskodrenicka zone, west of Kosovska Mitrovica
and in the plane of Kosovo (Kosovo Pole). Terrigenous-carbonate sediments
are represented, predominantly in neritic and more rarely in bathyal facies (Радойчип,
1975).
15.4. Sumadia Zone
This zone comprises the southern periphery of Banat, the area around Belgrade»
Sumadia, Eastern and Southeastern Kopaonik.
In Southern Banat (Vojvodina) the Lower Cretaceous is represented by Neocomian
limestones, clayey limestones and calcareous breccias; siltstones and radiolarites
are developed in some places. The Barremian and Aptian comprise sandstones,
sandy and organogenous limestones with Orbitolinidae and other foraminifera,
bryozoans, rudists, Nerinea and echinoderms. The Albian is not developed
(Анпелковип, 4975).
In the Belgrade region the series is developed in its full volume from the Berriasian
to the Albian included (А н h e л к о в и h, 1975).
The Berriasian is represented by calcarenites, breccia-like limestones and calcareous
sandstones with T. carpathica (M u r g., Fill.), Stenosemellopsis hispanica
(С о 1.), rare belemnites and ammonites, many bivalvs, brachiopods and
echinids.
The Valanginian is represented by claystones and marls which are poor in fauna.
The Hauterivian and the Lower Barremian are built of marls, sandy-clayey
marls, clayey-calcareous sandstones with intercalations of clayey limestones containing
characteristic cephalopods (А и h e л к о в и h, 1975).
Neocomian flysch is also widespread in the Belgrade region.
A considerable part of the Barremian and Aptian are connected with two
types of sediments: Urgonian (reef and subreef) and terrigenous. A substantial part
of Belgrade is built over these sediments.
Urgonian limestones are usually massive, with rudists and Orbitolinidae. They
contain intercalations of claystones, marls and rarely of sandstones.
In the southeast the Urgonian limestones pass into sandy-conglomerate sediments:
conglomerates, sandstones and calcarenites, among which there are Orbitolinidae,
gastropods and ammonites: Holcodiscus caillaudianus (d'Orb.), H.
perezianus (d'O г b\), Barremites ponticus (1С а г.), etc. These sediments are similar
to the Paraurgonian facies in the Pyrenees and in the Fore-Balkan.
The terrigenous type of Barremian-Aptian sediments replace the Paraurgonian
deposits in the southeast. They are designated by Serbian geologists as flysch
sediments, but in fact they are molasse-like in character, similar to the sediments
in the Roman Formation in the Fore-Balkan. They are represented by cross-bedded
aleuritic marls, siltstones and sandstones. They contain Orbitolinidae, ridists, brachiopods,
corals, etc. The peripheral fans of these sediments are the so-called clastic
Aptian sediments (sandstones, calcarenites and a few conglomerates) which con-
