An Investigation of explosive consolidation processes of W-Cu ultra-disperse and nano sized powder compositions are discussed. For theoretical calculations of the explosive loaded materials were used the hydrodynamic theory and experimental adiabatics of W and Cu. The stress-deformed state of the steel ampoule-containers was estimated using the solutions of elasticity theory. Copper tungsten (W-Cu) powder compositions were consolidated to full or near-full density by explosive-compaction technique. The industrial ...

The metamafic rocks are represented by amphibolite, garnet-bearing amphibolite and amphibole-bearing schists, associated with a series of supracrustal metasediments in Pan-African basement of the Bitlis massif. The geochemical data of the samples propose different igneous protolithes varying from calcalkaline basalt to andezite. The samples can be classified as Group-1(low Zr) and Group-2 (high Zr), all displaying various enrichments in large ion lithophile (LIL) and light rare earth (LRE) elements and depletion i...

The study area is located at the southwest end of Taurid Orogenic belt, around YanД±klar\cCiftlik- Karagedik (Fethiye-MuДџla) and covers approximately an area of 77 km2. In the study area magmatic and sedimentary rocks formed in Mesozoic-Senozoic period crop out. Eventhough the Upper Triassic-Low Jurassic Kayak\"oy formation represented by dolomite, cherty dolomite and dolomitic limestone occurs at the basement of the study area. This unit lies tectonically on the Upper Jurassic-Lower Cretaceous BabadaДџ formation...

Details presents in the paper realize at collaboration the Ministry of Science and Technological Development on project No 17004 R. Serbia. Presented carakterisics clivage in aspect on massif rock research in drillholes B-1k, B-2k, B-3k, B-4k and B-5k. Evaliation of rock stability, in which will be place tunnel axis, took from prospecting Krivelj`s River. Iinvestigations are: structural characteristicsa of rock massif, degree of disintegration, alteration degreee, fracture degreee and physico-mechanical characteri...

\cCakraz district of Bartın province in northwestern Turkey contains wide deposits of quartz sand. Regional geology consist of Lias aged carbonated claystones of Himmetpaşa formation, Barremian aged limestone, dolomitic limestones of Zonguldak formation and Aptian aged sandstone – carbonated sandstones of Kilimli formation. \cCakraz district quartz sand deposits are hosted in Himmetpaşa formation and usually occur as wide lenses in the host rocks. In this study major and minor element chemical analysis, petro...

This study focuses on the geochemical and mineralogical compounds of clay occurrences that had been interbedded low rank coals in Biga Peninsula, Turkey. The usages of these clay formations were also studied. Clay occurrences were formed and alternated along with Tertiary lignite seams in the peninsula where is one of the basic metallic and industrial mineral potential regions in Turkey. Chemical and mineralogical analyses were performed on thirteen clay samples from different lignite beds. The XRD analyses show t...

Kosovo is rich in coal resources / reserves. There are about 14 billion tones coal resources in Kosova. The coal in Kosova is used mainly in power (electricity) generation and less amount for heating. Kosovo coal is lignite type. Exploitation of coal is being donning in two open pits Bardh and Mirash. There is also a project for building of the new power plant (capacity 2000 MW). For this, supply of coal should be made by the new mine - Sibovci. The underground mining was abandoned in 1922. Now it is the surface m...

Kosovo has a varied geology that ranges in age from the Neo-Proterozoic to the Holocene. The geology is characterized by substantial structural features on a regional scale, including, normal faulting and thrusting. The area belongs to the External Vadar Zone (EVZ). The Volcanic complex Mitrovic\"e – Samadrexh\"e is dominated by Jurassic and Neogene volcanic rocks from several eruption centres, interlayered by metamorphic and sedimentary units. The survey area was determined in the adjacent area of the known Pb ...

A revaluation of the important of the climatic variations on the Earth in the last 120,000 years (Quaternary palaeoclimatological data) led us to render evident a special geodynamic moment around 40,000-39,000 years (ka) before present (BP). We have correlated this moment with a severe change of the precessional year duration caused by a modification of the rotational axis position under the influence of a cosmic body. We consider this cosmic event to be the capture of the Moon (by the Earth), former first planet ...

The investigation of the fluvial relief of the north-east side of Kosovo shows a particular scientific and practice interest, so our purpose is to give a circumstantial and full view of morphology and morphogenesis of this part during the evolution phases of its development. In the complex relief of this part, a very important part is the fluvial one, too, so, if we see it by its enlargement, it is ranged immediately after the structural relief, which is regarded to the fact that the fluvial morphogenesis phenomen...

A summary of abundance, quality and usage areas of the known bentonite occurrences in Turkey has been explained for this study. Bentonite that is one of the most important and abundant clays of Turkey has lower cost in comparison to other raw materials. Turkey has significant resources of bentonite that have been reported approximately 370 million tons base reserve. Also Turkey is one of the leading producers with 950 000 tons per year. Lower cost of bentonite in comparison to other raw materials for various usage...
