“…al. [33] have performed mineralogical and geochemical characterization of sedimentary rocks in the Croatian part of Pannonian Basin. The most common minerals they found in the fifty-two samples are smectite or illite smectite, even though there are some minor portions of kaolinite and illite in all samples.…”

Locally available materials, like clays, present a potential to meet the growing concrete demand and to produce more sustainable material. This paper reviews the behaviour of common clay minerals (kaolinite, illite and montmorillonite) giving an insight into the complexity of clay soils that usually appear as mixtures of minerals and impurities. It is therefore crucial to perform reactivity study when considering clay as supplementary cementitious material (SCM). The paper also shows major clay excavation sites in Croatia highlighting those which will be a part of the Swiss-Croatian research project ACT.

Pleistocene deposits are represented by aeolian and aquatic-aeolian sediments while in the Holocene, deposits are dominated by alluvial and subordinately by deluvial-proluvial sediments. Marsh sediments are less abundant. Similar distinctions of these sediments are applied on the Geological Map of the Republic of Croatia 1:300.000 (2009). Similar sediments are described by AVANIĆ et al. (2006) from the outcrop near Vojnić (Fig. 1A), and consist of silts, clays, gravels and sands which were deposited in an alluvial environment and belong to the informal Bistra Formation. The chronostratigraphic position of this formation is still under debate due to the lack of absolute dating evidence. AVANIĆ et al. (2006) suggest that the Bistra Formation spans a Pliocene-Pleistocene age. During mapping for the Basic Geological Map of the Republic of Croatia at 1:50.000 scale, two boreholes: Badel-1 (45°82'64''N; 16°09'98''E) at 71.50 m deep and Badel-2 (45°82'67''N; 16°10'09''E) at 84.40 m were studied in the area of the former "Badel" factory in Sesvete (Fig. 1). On this map, Quaternary sediments are subdivided on the basis of their lithology. In the Pleistocene, silts, clays, sands and gravels of the informal Bistra Formation (BS) are dominant while in the Holocene-Pleistocene, sands and gravels of the second terrace (t 2) are present. The Holocene is represented by (a) silts and clays of marsh environments and (b) sands, silts and gravels of alluvial environments. Within the investigated sediments of the boreholes, the deep blue mineral vivianite was

“…These types of calculations are based on the assumption that the SiO 2 /Al 2 O 3 ratio in terrigenous clay and silty clay is almost constant, and varies from 3.5 to 2.7. According to GRIZELJ et al (2007;2017) XRPD analyses of Miocene pelitic sediments from the Croatian part of the PBS revealed that most of the samples contain the same mineral phases, but they are present in different quantities in different samples. The ratio of SiO 2 /Al 2 O 3 can vary within one clay mineral group and varies considerably within different clay mineral groups.…”

In recent decades, there has been an increase in the use of diatomaceous earth (DE) as a natural insecticide because of its low mammalian toxicity, worker safety, low risk of food residues and the occurrence of resistant insect populations associated with the use of chemical insecticides. Therefore there is potential for research into known but previously undescribed Croatian mid-Miocene marine diatomites from the perspective of their potential as proper DE that could be mixed with plant extracts as a new formulation for grain storage protection. The marine diatomites belong to the Paratethyan near shore environment, deposited in the upwelling zone during a mid-Miocene temperate climate. Palaeontological, mineral and geochemical analyses were done on ten promising marly sediments from 26 outcrops and one borehole from the North Croatian Basin. The most important ingredient of diatomaceous sediments is silica (biogenic opal-A and SiO 2 bound in other silicate minerals including quartz, clay minerals, micas, etc.). The amorphous silica content of the tested Croatian diatomites is relatively low (50%) in comparison with the Celatom ® MN 51 standard (medium to high efficient DE) (73.6%), nevertheless they show in some part even slightly better efficacy against insects. It seems that the enhanced content of smectite in diatomaceous sediments also influences increased absorption of DE. Based on palaeontological results, the most efficient diatomites from the Podsusedsko Dolje and Markuševec (Medvednica Mt.) consist of the mid-sized planktonic Coscinodiscus group of species where Thalassionema nitzschioides dominate and is positively correlated with their absorption. The usage of Boströms' standard formula for getting opal-A from geochemical data was abandoned because of negative results and the modified Murdmaas' formula for hemipelagic sediments was applied. Preliminary results on the aforementioned diatomite (as inert dusts) show good efficacy against tested insects Sitophilus oryzae (LINNAEUS), Tribolium castaneum (HERBST) and Rhyzopertha dominica (FABRICIUS).
