Bányaföldtani megfigyelések a Gánt felsôlegelôi dolomitbányában.

The Gánt felsőlegelő dolomite quarry is located in the South-East edge of the Vértes, on the North- East side of the No. 8123 highway, at about 3 km distance from Gánt village. The total length of the pit wall in the Gánt felsőlegelő dolomite quarry is 4590 m. As a result of the mining activity, the dolomite has been explored in vertical direction at 46 meters. The diploporic dolomite is generally light or pale grey in colour, dense, hard and locally fragmented due to tectonic activity. At certain locations, light red and brown discoloration is observed by limonite formation that is the result of the precipitation from iron contaminated solutions filtrating through crevices. Mining geology observations confirmed the thickness of dolomite benches in the range of several cm to several m. Blocks are also observed in the extracted dolomite bulk. Volume of blocks is generally between 0.5-1.0 m3, sometimes 2-5 m3. The largest block ever observed had the volume of 18 m3. Shape of blocks is irregular, fragmented, eventually crumbled. The high quality dolomite products of the quarry can be utilized as crushed stone products for road construction (road base), as aggregate for concrete and - due to its frost resistance - as construction blocks. The dolomite/clay products can be used for embankments or in recultivation. The rich dolomite resources at the Gánt felsőlegelő dolomite quarry can provide high quality products for the region for a long time. [ABSTRACT FROM AUTHOR]
