Mineral resources in central Croatia: Geological potentiality and strategic importance

Mineral resource mapping is used as a tool for delimiting areas with high and low geological potential, all with the purpose of determining the strategic importance of certain mineral resources in a particular area. Utilizing a Geographic Information System (GIS) allows an expert user to rapidly evaluate all mineral raw material data. The goal is to identify exploration and exploatation opportunities of certain mineral raw materials. Research covered central part of Croatia, respectively the area of so called Internal Dinarides, which is generally built from Quaternary sediments of Pannonian basin (95 %) and a smaller part of magmatic and metamorphic rocks (5%). Precisely, the area in the administrative boundaries of Koprivnica-Križevci, Bjelovar- Bilogora and Sisak- Moslavina County is observed. This area is selected to demonstrate the usefulness of determining geological potential in the area where exploration for exploitation of mineral resources is common, and predictions of the occurrence of a particular lithologic member are necessary. Within lithological members of the observed area and taking into account all kinds of mineral resources which appear in the area, crushed stone, sand and gravel, brick clay and quartz (silica) sand were singled out as valuable mineral raw materials. Such research is currently being carried out in the legislative framework of Mining and Geology Studies. Their goal is, using modelled potentiality, to steer and facilitate explorations works, as well as the future exploitation of mineral raw materials in any given area.
