Abstract

Uz šumsku cestu od Dubravice prema teniskim terenima nalaze se izdanci klastičnih naslaga (pretežito lapora), u kojima su mjestimice nađeni fragmenti skeleta makrofosila, foraminifere, ostrakodi, ostaci riba i drugih organizama. Rađeni su terenski, laboratorijski, kabinetski i analitički radovi, te kalcimetrija. Metoda prilagođenog mokrog prosijavanja je rađena u sklopu laboratorijskog rada. Za analitički rad su računati indeksi raznolikosti, rađen je trokomponentni dijagram i računat je omjer plankton bentos. Taložni okoliš je interpretiran kao unutarnji šelf s obiljem nutrijenata i povremenim donosom slatke vode. Starost naslaga je badenska.

Abstract (english)

Along the forest road from Dubravica towards the tennis playground, outcrops of clastic sediments (mostly marls) comprise skeletal fragments of macrofossils, foraminiferae, ostracods, fish remains and remains of other organisms. Field, laboratory, office and analytic work and calcimetry have been done. Modified sewing technique has been done as a part of laboratory work. For analytic work, diversity indexes have been calculated, three-component diagram has been done and plancton/bentos ratio has been measured. Depositional environment is interpreted as te inner shelf, rich in nutrients, with temporary input of fresh water. Deposits are Badenian in age.
