Cím:	Examination of fluvial development on study areas of Upper -Tisza region/ Szabó József, Vass Róbert, Tóth Csaba Albert
Dátum:	2012
ISSN:	1842-4090 1844-489X
Megjegyzések:	Purpose of recent study is to show the fluvial evolution of the Upper-Tisza region on two study areas. In the Bereg Plain (from the border to the mouth of the Szamos) studying the deeply cut shore wall of the Tisza - partly due to meander cuts - together with the morphometric analyses of floodplain deposits and abandoned river beds yield information on the characteristics and pattern of natural accumulation. These indicate that the characteristics and pattern of recent sedimentation are determined primarily by the distance from active river beds. Characteristic feature of the youngest period is the accelerated accumulation rates (0.2-1cm/year) on the floodplains bordered by dams. These rates were determined by digital elevation models (DEMs); shallow boreholes and geodesical measurements. The part of the Tisza floodplain directly above the Tokaj gate (Bodrogzug) is special primarily because no flood preventing dams were constructed between the Tisza and the Bodrog thus the area remained a quasi natural fluvial development area free of intense cultivation up to now. The area is especially rich in forms characteristic for floodplains of the Great Hungarian Plain (abandoned river beds, levees, point bars, crescent beds, floodplain flats, etc.) annual (or even more frequent) flooding of which enable fluvial accumulation even today. Sedimentary analyses carried out with the help of drillings and in situ sediment traps show that accumulated sediments become finer gradually. Grain-size distribution of the sediment is depends on the distance of present (active) and abandoned river beds. Sediments from active beds and levees are coarse grained, while on floodplain flats are fine grained.

Cím:	The application of Earth Science-based analyses on a twin-kurgan in Northern Hungary / Tóth Csaba Albert, Pethe Mihály, Hatházi Ágnes
Dátum:	2014
ISSN:	1842-4090 1844-489X
Megjegyzések:	One of the biggest and archeologically still unexplored twin kurgan of Hungary was formed by the artificial piling up of a soil mass with a total volume of nearly 190 000 m3. The source locations of the heaped material were the originally 2.5-3 meter deep, long trenches that run along the base of the mounds. Based on the sediment-geological analysis of these kurgans, four separate layers can be identified. The uppermost stratum is a "chernozem"-type (black earth) recent soil (930 and 440-50 BP), under which the hillocks' artificially accumulated loessy soil with mixed structure (5760 - 90 BP) can be found. Below them, there is a layer of buried, fossil brown soil (4450 - 60 BP), which can rather be considered a type of forest soil, due to its higher clay and lower organic substance contents, compared to that of the recent soil. Finally, below the buried soil, the base rock mainly consists of yellow-brown loess. By deducting the age of the natural, undisturbed soil of the boundary (located farther away from the mounds) from the age of the fossil soil (both determined by radiocarbon dating), the result gives the approximate date when the 3rd soil layer was buried, i.e. when these kurgans were being built. The corrected results of the radiocarbon dating - which was performed on both the total organic substance content and the humic acid fraction of the fossil soil - turned out to be very similar (2590-120 and 2570-110 BP, respectively). Based on this result, it can be presumed that the creation of these kurgans is closely linked to the Scythian culture which settled in the Carpathian basin in the 6th century BC. Judged by size of these hillocks, they were probably burial mounds of Scythian princes or other dignitaries. Based on the high number of rock pieces - mainly Triassic chalk-stone and Miocene rhyolite tuff - found in the surrounding plough-lands and during the excavation of the sepulchral mounds, it has been established that inside these kurgans there are tombs built of stone. Based on the lithological analysis of the rock samples, these pieces originate from the Bükk Mountains and the Szerencsi island hill (from an approximately 16?20 km distance). Our geophysical (magnetic) investigations revealed the existence of a stone crypt (about 40 m in diameter) inside these mounds. At the same time, the detected magnetic anomalies in the adjacent foreground also indicated a number of Sarmatian graves with circular ditches (3-4th century AD). Based on these findings it can be established that the area and immediate vicinity of the Zsolcai-mounds - rising on an unflooded terrace of the Sajó River - counted as an important burial place for centuries in ancient times.
