Abstract

Cilj ovog rada bilo je određivanje mineraloških značajki osam uzoraka srednjoeocenskih lapora na uzorcima prikupljenim na području Čepikuća i na području susjednog poluotoka Pelješca. Korištena je rendgenska difrakcijska analiza i metoda kalcimetrije. Prema udjelu karbonatne komponente uzorci su lapori ili kalcitom bogati lapor. Analizom rendgenske difrakcije kod orijentiranih preparata utvrđen je sastav glinovite frakcije: klorit, illit, smektit, klorit/smektit, kaolinit/smektit,... More dioktaedrijski illit/vermikulit, dioktaedrijski vermikulit, illit/klorit i illit/smektit. Utvrđeni mineralni sastav sugerira na izraženije fizičko trošenje stijena što vežemo uz hladnije i suho klimatsko razdoblje, a miješano-slojne gline ukazuje na sezonalnost klime tj. izmjenu godišnjih doba.

Abstract (english)

The aim of this work was to determine the mineralogical characteristics of eight samples of marls, Middle Eocene age, on samples collected in the area of Čepikuće and in the area of the neighboring Pelješac peninsula. X-ray diffraction analysis and the calcimetry method were used. According to the proportion of the carbonate component, the samples are marls or calcite-rich marl. X-ray diffraction analysis of oriented preparations determined the composition of the clay fraction:... More chlorite, illite, smectite, chlorite-smectite, kaolinite-smectite, dioctahedral illite-vermiculite, dioctahedral vermiculite, illite-chlorite and illite-smectite. The established mineral composition suggests a more pronounced physical weathering of the rocks, which we associate with a colder and drier climate period, and the mixed-layer clays indicate the seasonality of the climate, i.e. the change of seasons.
