Abstract

U radu je rekonstruirana dubinska geološka građa na području u kojemu su definirane
pozitivne geotermijske anomalije grada Zagreba. Litološke značajke istraživanog područja
su opisane pomoću izrađenih litoloških stupova dubokih bušotina na sedam lokacija. Na
temelju korelacije litoloških stupova bušotina s interpretiranim refleksijskim seizmičkim
profilima odabrana su tri stratigrafska horizonta koji su kartirani pomoću računalnog
programa Landmark i to: 1) stratigrafski horizont koji odgovara bazi neogenskih naslaga,
2) stratigrafski horizont koji odgovara bazi panonskih naslaga i 3) stratigrafski horizont
koji odgovara bazi plio-kvartarnih naslaga. Za navedene stratigrafske horizonte
konstruirane su dubinske strukturne karte korištenjem zakona brzina na sedam bušotina.
Ustanovljeno je da su pozitivne geotermijske anomalije povezane s trijaskim dolomitnim
tijelom koje je dobar toplinski vodič i ima dobru sekundarnu poroznost i vodopropusnost.

Abstract: This thesis presents a reconstruction of subsurface geological structure in area of the city of
Zagreb characterized by positive geothermal anomalies. Lithology of the area is described
by constructed lithological columns of seven deep boreholes. Lithostratigraphic correlation
of borehole data, together with interpretation of reflection seismic sections in Landmark
software enabled mapping of three stratigraphic horizons: 1) the base Neogene horizon; 2)
the base Pannonian horizon; and 3) the base Pliocene-Quaternay horizon. For these three
horizons structure contour maps in TWT scale were constructed first and then converted
into structure contour maps in metric scale by means of borehole velocity model. It is
confirmed that geothermal anomalies of the city of Zagreb are related to Triassic dolomite
body characterized by good thermal conductivity and secondary porosity.
