Abstract

Cilj ovog rada bilo je određivanje mineraloških značajki četiri uzorka
donjoeocenskih lapora na uzorcima prikupljenim na području Slanog potoka u Vinodolskoj
dolini. Korištena je metoda kalcimetrije i rendgenska difrakcijska analiza. Prema udjelu
karbonatne komponente uzorci su lapor ili kalcitični glinjak. Rendgenskom difrakcijskom
analizom, orijentiranih preparata, utvrđen je sastav glinovite frakcije: klorit, illiti, illitsmektit,
dioktaedrijski illlit-vermikulit i kaolinit. Utvrđeni mineralni sastav sugerira
dominaciju fizičkog trošenja na okolnom kopnu, no i ograničeno kemijsko trošenje te
sezonalnost klime.

Abstract (english)

The aim of this seminar was to determine mineralogical properties of Lower
Eocene marl on the samples collected in the area of Slani potok, Vinodol Valley. The
methods used in this seminar were calcimetry and X-ray diffraction analysis. By
proportion of the carbonate component, the samples are marl or calcitic claystone. Clay
mineral assemblage was determined from oriented samples using X-ray diffraction
analysis. The clay minerals present in the samples are: chlorite, illite, illite-smectite,
dioctahedral illite-vermiculite, and kaolinite. The determined mineral composition suggests
the dominance of physical weathering on the adjacent mainland, but also limited chemical
weathering and seasonality of the climate can be assumed.
