(SGEM Scientific GeoConference, 2009, G. Kansun, H. Bas, K. Asan)

Show more

The Alanya unit consists of threeimbricate metamorphic nappes: These are Cambrian - Upper Permian aged The Mahmutlar group (the lower nappe), The Sugozu melange (middle nappe) (Late Cretaceous-Paleocene), and Lower Cambrian - Middle-Upper Triassic aged The Yumrudag group (upper nappe). The pelitic and semipelitic schists of the Alanya unit are shale and wacke in origin. These received material from acidic and probably medium compositional volcanic arc granites and deposited on the active continental margin and pro...

COMPACTION OF TUNGSTEN CONTAINING ULTRA-DISPERSE POWDER IN DYNAMIC CONDITIONS

(SGEM Scientific GeoConference, 2009, N. M. Chikhradze)

Show more

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 ...

EARLY MIOCENE MILDLY-ALKALINE VOLCANISM IN THE KARACADAG AREA (CENTRAL ANATOLIA, TURKIYE)

(SGEM Scientific GeoConference, 2009, K. Asan, H. Kurt)

Show more

In the Karacadag area (Central Anatolia, Turkiye), small volumes of mildly-alkaline lavas associated with large volumes of calcalkaline lavas crop out. 40Ar/39Ar age data indicate that the mildly-alkaline lavas were erupted during Early Miocene (ca. 18 Ma). The lavas are composed of alkali basalt, hawaiite, mugearite, benmoreite and trachydacite, and include olivine, ortho/clinopyroxene, amphibole, plagioclase, opaque and rare anorthoclase. The mildly-alkaline lavas have a sodic tendency (Na2O/K2O = 1.5-3.2) and r...

Nowadays, the problem of fine micro-and nano-scale В«invisibleВ» gold, remains urgent, with the substantial loss of metal during enrichment of sulphide ores. Mineralogical studies show that the vast majority of native gold in sulphides is in the form of fine, dust and thin particles, with a subordinate amount is very small and petty. According to the confirmed reserves of gold, Kazakhstan is among the top ten countries of the world. The considered balance stock of deposits is 196 (126 autochthonous, 47 complex, 23...

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.

THE CAPTURE OF THE MOON BY THE EARTH AROUND 40,000 YEARS BEFORE PRESENT FROM THE GEOLOGICAL PERSPECTIVE

(SGEM Scientific GeoConference, 2009, M. Ticleanu, N. Ticleanu, R. Nicolescu, A. Ion, GH. Borcan)

Show more

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...
