Abstract

Najvažnija zagrebačka planina i oaza mira za brojne zagrepčane te simbol bijega u
prirodu iz užurbanog glavnog grada, u sebi skriva dugu povijest. Na današnji položaj izdignula se
prije oko 12 milijuna godina burnim tektonskim procesima. Na njoj pronalazimo sve osnovne
vrste stijena i fosile iz gotovo svakog razdoblja u povijesti. Jezgra Medvednice izgrađena je od
metamorfnog zelenog škriljavca koji krasi pročelja mnogih objekata na Medvednici kao što su
Tomislavov dom i kapelica Majke Božje Sljemenske Kraljice Hrvata. Drugu najučestaliju stijenu
Medvednice, litotamnijski vapnenac ili litavac, možemo vidjeti na mirogojskim arkadama i
Zagrebačkoj katedrali. Važan dio tih stijena su i ostaci organizama, poput algi i ljuštura školjkaša,
koji su živjeli u tadašnjim plićacima Panonskog mora koje je okruživalo, a dijelom i prekrivalo
Medvednicu. Nažalost, litavac je podložan kemijskom i mehaničkom trošenju zbog svog
vapnenačkog sastava i porozne građe te ne predstavlja izdrživ materijal zbog čega se na katedrali
zamijenjuje talijanskim travertinom. Kameno blago Medvednice iskorištavano je od davnina, a
mnogi napušteni kamenolomi danas predstavljaju mjesto okupljanja za brojne znanstvenike i
zaljubljenike u prirodu jer se u njima mogu naći brojni fosili i minerali. Ostaci različitih
organizama pokazatelj su promjena paleookolišta tijekom povijesti i složenoj geološkoj prošlosti
Medvednice koju sam pobliže objasnila i prikazala u ovom seminarskom radu.

Abstract (english)

The most important mountain of Zagreb and the oasis of peace for many citizens of
Zagreb symbolizing escape from the busy capital, hides a long history. About 12 million years
ago, today's form of Medvednica mountain emerged in tectonic processes. It contains all the main
types of rocks and fossils from almost all periods in history. The Medvednica mountain is made
of a metamorphic green slate that adorns the facades of many buildings in Medvednica such as
Tomislav's home and chapel of the Mother of God of the Sljeme Queen of Croats. The second
most common rock of Medvednica mountain, characteristic limestone or „litavac“, can be seen at
the arcades of Mirogoj and the Zagreb cathedral. An important part of these rocks is the remains
of organisms, such as algae and shellfish, who lived in the beaches of the Pannonian Sea that
surrounded, and partly covered Medvednica. Unfortunately, limestone from Medvednica
mountain is subject to chemical and mechanical wear due to its composition and porous material
and is not a viable material, which is why the cathedral is replaced by Italian travertine. Stones of20
Medvednica mountain have been exploited since ancient times, and many abandoned quarries
represent a gathering place for many scientists and nature lovers, as numerous fossils and
minerals can be found. The remains of different organisms are the indicator of the change of
paleoenvironment during the history and complex geological past of Medvednica, which I
explained and presented in this work.
