AB  - The study of aquifers of the Lece andesite complex (LAC) and its surroundings yielded a new procedural stepwise analysis that allowed the assessment of the origin of elements, particularly in areas affected by both anthropogenic and natural influences. The methodology uses the mineralogical composition of the rocks, including the elements available in rocks and groundwater. This study
analyzes the element ratios B/Cl−, Na+/Ca2+, Ca2+/Mg2+, HCO3−/Cl−, and Na+/Na+ + Cl−; the correlations are coupled with a statistical analysis. In addition to reevaluating the already published water content, we provide an important new dataset. The results show that the main source of the water contamination with the elements B, F, U, As, Cu, Fe, Zn, Co, and Ni is the processes occurring
at the contact between the groundwaters and non-altered/altered (propylitized) andesite rocks. This is also observed in the waters extracted from crystalline schists. The results may help develop an efficient use and assessment of the qualitative water potential of the LAC reservoirs. Similarly, the results highlight the applicability of the groundwaters, facilitating their regional research and use, further encouraging new initiatives for the preservation and protection of human and animal health.

AB  - Rocks of the Diabase-hornfels formation built great part of Zlatar and its surrounding area. Into the composition of this formation enters: sandstones, siltstones, claystones, hornfels, and fewer limestones, as representatives of the sedimentary rocks; whereas magmatic rocks consist from diabases, spilites, gabbros, and less serpentine. It is very interesting occurrence of barite in this formation, whose outcrop was discovered at the area of about 100 m2. In this paper barite was crystallographicaly and chemically characterized. Observed values of the inter-planar spacings (d), as well as calculated unit cell dimensions of: a = 7.146(1) Å; b = 8.869(1) Å; c = 5.446(1) Å; and V = 345.14(8) Å3; are something smaller regard to the literature data which are adequate to “pure“ barite. Such is consequence of partially (about 2 %) isomorphic substitution of Ba2+ with Sr2+ and Ca2+ cations which have smaller ionic ratio. Presence of Pb2+ cations in the structure is neglected, so the crystal-chemical formula of the investigated barite could be presented as: (Ba0.99Ca0.01Sr0.01)1.01S1.00O4.
