Abstract

Na plaži Bukva u blizini Pridrage nalazi se dobro otkriveni slijed naslaga koji do sada nije bio detaljno istraživan. Analizom i facijesnom interpretacijom podataka prikupljenih na terenu utvrđeno je da se radi primarno o kalciklastičnim šelfnim naslagama eocenske starosti. Na temelju veličine zrna naslage su podijeljene na kalklutite, kalksiltite, kalkarenite i konglomerate. Utvrđeno je da se naslage mogu podijeliti u četiri facijesne asocijacije koje odgovaraju četirima različitim zonama... More šelfa: odobalje (offshore), prijelazna zona (offshore-trasition), obalno lice (shoreface) i plaža (beachface). Naslage odobalja primarno su građene od kalklutita. Naslage prijelazne zone građene su od izmjena kalklutita, kalksiltita i kalkarenita, naslage obalnog lica primarno su građene od kalkarenita, a naslage plaže izgrađuju slojevi klast-potpornog konglomerata. Uz ove četiri zone, utvrđeno je postojanje MTD-ova (mass-transport deposits) unutar naslaga odobalja u vidu kaotičnih slojeva matriks-potpornih konglomerata. Zatim su ove naslage uspoređene s naslagama u blizini Novigrada i utvrđeno je kako postoji velika mogućnost da su oba slijeda taložena istovremeno u istom taložnom prostoru (u thrust-top bazenu unutar wedge-top zone Sjevernodalmatinskog predgorskog bazena) te je iznesena pretpostavka s kojim dijelom novigradskog slijeda bi se poklapao slijed u blizini Pridrage.

Abstract (english)

On the Bukva beach, near the town of Pridraga, there is a sequence of deposits that has not yet been investigated in detail. Facies analysis and interpretation of the data collected in the field determined that these are primarily calciclastic shelf deposits of Eocene age. Based on grain size, the deposits are divided into calcilutites, calcisiltites, calcarenites and conglomerates. The deposits were divided into four facies associations corresponding to four different shelf zones:... More offshore, offshore-transition zone, shoreface and beachface. The offshore deposits are primarily made of calcilutites. The deposits of the offshore-transition zone comprise alternations of calcilutites, calcisiltites and calcarenites. Shoreface deposits are primarily made of calcarenites, and the beachface deposits are made of beds of clast-supported conglomerates. In addition to these four zones, the existence of MTDs (mass-transport deposits) was established within the coastal deposits in the form of chaotic layers of matrix-supported conglomerates. These deposits were compared with deposits near the town of Novigrad and it was determined that there is a high possibility that both sequences were deposited simultaneously in the same depositional area (in the thrust-top basin within the wedge-top zone of the North Dalmatian foreland basin) and an assumption was made that a part of the Novigrad sequence would match the sequence near Pridraga.
