Cím:Archaeometric investigation of the stone tools of the Vatya culture (Pest county, Hungary) / Farkas-Pető Anna, Horváth Tünde, Papp István, Kovács-Pálffy Péter
Dátum:2014

Megjegyzések:With the analysis of the middle Bronze Age (2000-1350 BC) Vatya culture findings in Pest county (Central Hungary) comprising of more than 400 polished stone tools and instrument tools this is the first archaeometric study with such scale in Hungary. In order to characterize petrographically the raw material of the stone tools macroscopic and microscopic stone analyses were made together with mineralogical and geochemical analyses. In the course of the work a new digital database the ArchaeometricStone Tool Database was established. Based on the results, the material of the instrument stones is mainly sandstone and quartzite that were easy to collect from their source areas. Local volcanics, mostly amphibole containing andesite variations dominated among the material of the polished stone tools. Ophiolites (metamorphic basic rocks, serpentinized basic and ultrabasic rocks) were the raw-material of stone axes thatindicate either more distant travels for raw-material or exchange import.

Cím:Behaviour of ladle slag primary and secondary minerals in slag heap considering utilisation / Koleszár Péter, Papp István, Kozák Miklós, Kónya Péter, McIntosh Richard William, Grega Oszkár
Dátum:2016
ISSN:1842-4090 1844-489X
Megjegyzések:Secondary steelmaking slags contain numerous types of minerals such as larnite and various Ca-aluminates. Fresh ladle slags are unstable in the atmosphere disintegrating into fine white dust. The modification change of larnite (C2S) is the main cause of this phenomenon. The freshly formed white slag powder is unprotected against wind erosion. When water is sprinkled on it, however, a solid crust is formed instantly. According to the results, this hard layer contains calcium aluminate hydrate causing quick bonding and reducing the threat of wind erosion significantly. The major composing minerals of slags belong to two groups: the gehlenite?akermanite series belonging to sorosilicates and the larnite?bredigite series that belong to nesosilicates. In very small quantities these slags also contain various heavy metals. The most characteristic among them is barium that is mostly precipitated as non-soluble barite in the course of the disintegration of the slag therefore it presence no environmental risk. The chemical composition of slags determines their possible utilization which is also discussed in the paper.

Cím:Evaluation of the relationship between soil properties and vineyards: a case study from a cool climate wine region of Hungary / Nagy Richárd, Zsófi Zsolt, Papp István, Földvári Mária, Kerényi Attila, Szabó Szilárd
Dátum:2012

Megjegyzések:Sedimentological investigations and thermal analyses were carried out in a steep slope vineyard in 2007 (Nagy-Eged hill - located in the north-eastern part of Hungary). This area is proned extremely eroded due to its significant steepness and vine-growing cultivation. Soil thickness is approximately 50 cm near the top while at the bottom the thickness of horizon A alone reaches up to 150 cm. According to the results the ratio of fractions smaller than 0.02 mm and those larger than 2 mm between the top and the bottom is reverse. In the lower slope section the ratio of particles smaller than 0.02 mm is three times that in the upper slope section. Similarly the ratio of particles larger than 2 mm in the lower slope section is five times that in the upper slope section. The quantity of clay minerals measured by thermal analysis is larger than that measured by elutriation indicating that a part of them exceeds the diameter of 2?m. Our results revealed the effects of soil erosion on the mineral composition of the soil. The amount of clay minerals (e.g. montmorillonite) is about the double in the lower section, than in the upper of the slope. Clay minerals caused negative water budget in the upper levels resulting in the occurrence of anthropogenic water deficit as the consequence of soil erosion. Therefore vegetative growth of plants in the lower areas is better than that of those in the upper areas.
