Abstract

Na užem području potoka Šiškinovca na Plješevici terenskim radom i mikropetrografskom
analizom izdvojena su 4 trijaska litofacijesa: (L1) Litofacijes mikritnog vapnenca, (L2)
Litofacijes ooidnog vapnenca, (L3) Litofacijes svijetlosivih vapnenaca, (L4) Litofacijes
vulkanoklastita, i jedan permski (L5) Litofacijes gipsa. Napravljene su mikropetrografske
analize stijena oko izvorišnog područja potoka Šiškinovca te fizikalne i kemijske
karakteristike vode potoka i izvora iz Gornjeg Zaklopca. Analizom mineralnog sastava
potočnog sedimenta i geokemijskim analizama vode utvrđena je povezanost petroloških
značajki stijena na istraživanom području s geokemijskim karakteristikama vode potoka
Šiškinovca. Kemijskim analizama vode utvrđeno je da duž cijelog potoka Šiškinovca te na
izvorina u Gornjem Zaklopcu imamo povećane koncentracije klorida i sulfata. Ovi
pokazatelji potvrđuju postojanje evaporitnih naslaga u podzemlju, koje voda otapa. Voda
potoka Šiškinovca pripada magnezijsko – bikarbonatnom i magnezijsko – sulfatnom tipu
voda, dok voda s izvora u Gornjem Zaklopcu pripada miješanom tipu voda. Svi rezultati
potvrđuju hipotezu da petrološke značajke stijena na području potoka Šiškinovca imaju
značajan utjecaj na geokemijske karakteristike vode potoka.

Abstract: Petrological and geochemical features of Šiškinovac creek on Plješevica mountain were
explored. Five lithofacies : (L1) lithofacies of micritic limestones, (L2) lithofacies of
ooidal limestones, (L3) lithofacies of light gray limestones, (L4) lithofacies of
vulcanoclastics, (L5) lithofacies of gypsum are determnied by field work and
micropetrographic analysis. Micropetrographial analysis of rocks in the area of Šiškinovac
creek were made. Physical and chemical characteristics of stream water were analyzed as
well. Good correlation between petrological characteristics of the rocks in the study area
and geochemical characteristics from Šiškinovac creek and springs in Gornji Zaklopac has
been determined. Chemical analysis of water from Šiškinovac creek and springs in Gornji
Zaklopac showed high concentracions of cloride and sulfate. These indicators confirm the
existence of mineral halite and other evaporite minerals that were gradually dissolved by
water of Šiškinovac creek (magnesium – bicarbonite rich and magnesium – sulfate rich).
The water of springs in Gornji Zaklopac belong to the mixed type of water. All results
confirm the hypothesis that the petrological characteristics of the rocks in the spring area of
Šiškinovac creek have a significant impact on geochemical characteristics of stream water.
