One of the impressive geological formations in Bosnia and Herzegovina is part of the Dinarides Central Ophiolite Zone, known in literature as the Bosnian Ophiolite Zone.Within the ophiolite zone, there are 6 ophiolite complexes in Bosnia among which the Krivaja-Konjuh Ophiolite Complex stands out with its size.The paper presents the results on research to date of fracture (vein) minerals in the Bosnian Ophiolite Zone, with accent put on research of vein (fracture) minerals on the southern edge of the Krivaja-Konjuh Ophiolite Complex.The following were conducted in the research on fracture (vein) minerals: an optical examinations by polarization microscope, x-ray examinations and chemical analysis by an electronic microprobe.The following were determined as fracture (vein) minerals in amphibolite rocks: prehnite, zeolite minerals (laumontite, thomsonite, mesolite and analcime), epidote-clinozoisite, chlorite, calcite, then plagioclases, quartz, garnet minerals and corundum.In contact zone between these rocks and metadiabases, the followings were determined: prehnite, epidote and subordinate clinozoisite and quartz.

Krivaja-Konjuh ultramafic complex is mainly constructed of ultramafic rocks associated with different varieties of igneous rocks (gabbro, dolerite, diabase, spilite, keratophyres, granitoids) and metamorphic rocks (amphibolites, amphibolite schists and eclogites). This paper presents results of mineralogical and chemical analysis of ultramafite rocks (peridotite-lherzolites) samples in the southern part of Krivaja-Konjuh massif. The samples were examined optically, by using method of X-ray fluorescence spectroscopy and electron microprobe method. Optical results showed that lherzolites have uniform textural characteristics and mineral composition. Results of chemical studies on these rocks demonstrated modal composition with high content of MgO, low content of CaO and high content of MgO:FeO (about 5 and up). Based on CIPW normative system, their composition is uniform with a very small variation in the content of diopside, with a slightly larger variation in the content of olivine. The rhombic pyroxene in composition correspond to enstatite and monoclinic pyroxenes are diopside by the composition. Spinel in peridotites are Al spinels and Al chromium spinels.

Metallogenic zone Borovica-Vares-Cevljanovici is built of Triassic clastic and carbonate formations that established the presence of significant deposits of iron and complex sulphide-barite deposits. Metalliferous zone Triassic sediments Vares area is located north of Sarajevo at a distance of about 35 km in a straight line. It stretches a distance of about 25 km and an average width of about 2.5 km. Triassic sediments cover an area approximately 70 km 2 , while the brighter part is about 30 km 2 . Systematic geological studies with shorter intervals were performed in the period from 1967 to 1989, when it was interrupted by the exploitation of the only open reservoirs Veovaca. Summing up the results of research of complex sulphide- barite occurrences and deposits in the area are clearly distinguished three groups were identified: north-group deposits and occurrences (the village of Borovice), and the central group of deposits and occurrences-Veovaca, Orti, Seliste, Prijeljev, Droskovac, Brezik, Smreka south and south-eastern group deposits and occurrences: Barice, Brgule, Smajlova forest. Carried out systematic geological exploration works in the period 1967-1989 was executed evaluation of reserves of lead, zinc and barite deposits in Veovaca, Orti, Rupice, Brestica-Jurasevac, and other sites are only indicated which leaves room for further research. The environment Veovace, the localities Seliste, Orti and Prijeljev obtained are indications interesting mineralization and ore, which would support future prospects in this area. The paper gives an overview of the results of research and quality of reserves of lead, zinc, barite, iron, chromium, manganese metallogenic zone Juniper-Vares-Cevljanovici. Displayed are the geological, mineralogical and chemical characteristics of these data explains the genesis of individual deposits. Previous geological, geochemical, geophysical and exploration drilling and underground mining works were found interesting mineralization and mineralization, indicating the perspective of this area.

Bosnia and Herzegovina is characterized by heterogeneous geological structure, and a high degree of tectonic and the seismic activity as well as various relief and the climatic characteristics and water flows of different gradients. All this reflected on engineering-geological characteristics of the terrain.The main causes of landslides' activation are changes in level of underground waters, chopping down of forest, great rainfalls, snow melting, long drought periods, changes in slopes, changes in load of a slope, rock's wastage, uncontrolled diversion of surface waters, earthquakes etc. Researches on landslides are carried out in order to establish the cause of landslide's origin and to find out efficient overhaul measures. Landslide's overhaul success depends not only on established causes of landslide's origin, but also on use of technical measures for stopping that process. Overhaul measures' carrying out is important in protection of the environment.This paper presents an analysis of co-action of natural factors and negative anthropogenic effect in a settled area, where landslides appear, by its studying and eliminating of causes we are creating the conditions for a successful stabilization of landslides. The paper shows some characteristic landslides with defining of geomorphologic, geologic, engineer geologic, hydrogeologic and geotechnical characteristics of the terrain.

Within the project task for the road M-17,3 Buna-Neum, section Neum-Stolac, several variants have been considered and the section has been divided into several sub-sections. The sub-section Stari Neum-Kisevo in the length of cca 3 km has already been built, as well as the sub-section of Kisevo-Brocanac, with length cca 8,5 km. Within the sub-section Brocanac-Drenovac, which construction is in progress, two main variants of the route have been set aside, namely the blue and the red one. The blue route starts from east of the Brocanac village, on mileage km 11+300 if counting from the beginning of the road in Stari Neum, and it follows the corridor of the existing road between Brocanac and Drenovac.The red variant, as well as the previous one, starts from east of the Brocanac village, passes south of the Hutovo village, near the Glumin village, and approaches to the blue variant in the region of Trnovski brijeg. After that, it goes again towards south and over the Burmazi plateau it approaches to Drenovac, while at Varda it approaches to the blue variant and the existing route on north. For adopted blue variant there have been analyzed geomorphologic characteristics, geological structure, and hydrogeological and engineering geological, as well as seismic characteristics of the terrain. Reconnaissance of the terrain has also been done, and all previous documentation has been used as well as results of the former conducted geological investigations. As a basic point there have been used the Main Geologic Maps, papers Ston and Metkovici 1:100 000 with legends.

In the area Bosnia, landslides on natural slopes are frequent occurrences that imperil some housing units, settlements, economic units and people's life or they imperil traffic safety on the roads, degrade agriculture and forest lands and they also lead to dislocation of surface and underground waters. The main causes of landslides' activation are changes in level of underground waters, chopping down of forest, great rainfalls, snow melting, long drought periods, changes in slopes, changes in load of a slope, rock's wastage, uncontrolled diversion of surface waters, earthquakes etc. Researches on landslides are carried out in order to establish the cause of landslide's origin and to find out efficient overhaul measures. Landslide's overhaul success depends not only on established causes of landslide's origin, but also on use of technical measures for stopping that process. Overhaul measures' carrying out is important in protection of the environment. This paper presents an analysis of co-action of natural factors and negative anthropogenic effect in a settled area, where landslides appear, by which studies and removing the causes are made conditions for the successful stabilization of landslides. The paper shows some characteristic landslides with defining of geomorphologic, geologic, engineer geologic, hydrogeologic and geotechnical characteristics of the terrain..

In the paper, a general overview of hydrographical-geomorphologic and geologic characteristics of terrain within the Upper Neretva basin, starting from a wider space of the inter-entity boundary line up to the source river zone, was given. On the basis of OGK: Kalinovik, Foca, Nevesinje and Gacko, a geological map of the river basin was made. According to tectonic structure, the terrain belongs to Zone of Mesozoic limestone and Palaeozoic schist, and the High Karst Zone. The tectonics of the terrain is complex. Along with the folded tectonics, radial tectonics is also expressed. Within the studied terrain, structurally-facial units are distinctive. Along with general characteristics, hydrogeologic and engineering-geological characteristics of terrain were presented as well, and the basic data on seismicity were given. Within the engineering-seismic research a calculation of parameters of seismic forces, at a level of the basic rock, was made. For the purpose of better understanding of hydrogeologic relations in the stream basin, and water abundance inside the specific section of the Neretva, a classification of rock masses and the river basin delimitation were performed. The boundary of river basin-water parting was determined on the grounds of analysis of geologic structure, geomorphologic relations and research of underground water connections. By researching the hydrogeologic relations and characteristics of the included rock masses, it was determined that at the bottom of the Neretva valley (canyon), as well as on high sections of slope sides exist perennial and periodic intermittent springs of different abundance.

The Bosnia River is the longest river in Bosnia and Herzegovina. It rises beneath the Igman Mountain, close to Ilidža, locality of Vrelo Bosne. The river flows through the central part of Bosnia and after 270 km of the course, near Bosanski Samac, it empties into the Sava River. The Bosnia River basin is morphological heterogeneous, which is in connection with the geological structure of the terrain. In the source part of the Bosnia River there is the huge Sarajevo-Zenica valley with Dinaric stretching direction. Morphological, it consists of a number of smaller or larger fields, so that in its upper reaches, the Bosnia River runs through the Sarajevo, Visoko, Kakanj and Zenica fields. In the middle reaches, the river breaks through the gorges cut into the firm rocks, Vranduk-Nemila and Maglaj-Doboj, while in the lower reaches, from Doboj to the mouth, it flows by the unstable riverbed through the alluvial plain where it makes number of branches, islands and curves. This paper gives the analysis on geomorphologic and hydrographic characteristics, then geological-tectonic, hydrogeological and engineering-geological characteristics of the Bosnia River basin in its upper reaches. During the work, there have been used methods of analysis and synthesis, cartography and terrain-research method as well as statistic and comparative method. During the research, the following documentation have been used such are sheets OGK (The Main Geological Maps, scale 1:100 000) of Sarajevo, Zenica,Vares, Bugojno and Prozor, HG (Hydrogeological map, scale 1:100 000) of Yugoslavia, and attached legends for these papers as well as literature data.

In amphibolite rocks, in the southern edge of Krivaja-Konjuh ultramafic massif, six samples are separated (from localities Stupcic I, Stupcic II, Pobilje, Donja Vijaka and Seliste) in which occurrences of minerals of chlorite group are confirmed using optical tests. Mineral composition of samples of rocks is checked using x-ray analysis on the instrument of brand Philips with CuKα radiation with graphite monochromator. Chemical composition of mineral-chlorite in rocks was determined using electronic microsonde (ARL-SEMQ). Analyses of chlorite were calculated in accordance with recommendations of HYPER-FORM (S. Borg, A. Moggesie and E-Bjerg, 1991). Calculation of formulas of chlorite was done on the basis of 28 O and 36 (O, OH). In Bosnia and Herzegovina, minerals of chlorite group are very frequent and developed compounds in igneous, sedimentary and metamorphic rocks. Even though they are mentioned in numerous petrography and mineralogy papers, most of the authors of petrography papers describe chlorites as members of the mineral groups, and articles where more detailed selection or description of certain types of chlorite are given are more rare. Quantity of chlorite in amphibolite rocks in the area of Vijaka is variable. Chlorite in amphibolite rocks in the area of Vijaka occurs in the shape of bands at contacts of amphibolite rocks with ultramafic rocks. In the crust of decaying of amphibolite rocks. As inclusions in corundum, garnets, amphiboles, pyroxene, plagioclase, and in celyphitic rim of garnets as a product of retrograde metamorphism in the hydrothermal conditions of metamorphism.

Corundum-bearing amphibolites are part of the metamorphic basement of the Krivaja–Konjuh ultramafic massif in the Dinaride Ophiolite Zone in Bosnia. Pinkish corundum occurs as porphyroblasts and together with edenitic–pargasitic hornblende and anorthite within the amphibolites. Based on major and trace element contents, the protoliths of the corundum-bearing amphibolites were tholeiitic gabbro cumulates. Geothermobarometric estimations on the corundum-bearing amphibolites yielded preliminary P–T conditions of 620–830 °C and 6–10 kbar for amphibole and plagioclase inclusions inside corundum and 4.5–8 kbar for the main metamorphic assemblage. These estimates are thought to reflect the metamorphic conditions achieved during the Late Jurassic obduction of the Krivaja–Konjuh ultramafic massif onto ophiolite mélange. This study documents the mineralogy, petrology and geochemistry of these unusual corundum-bearing ophiolite-related edenite–pargasitic amphibolites.
