Geochemical Evaluation Sediments and Water of Shurabil Lake, Northwest of Iran
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2012, Vol 3, Issue 12
Abstract
Shurabil Lake, situated in south west of Ardebil City (Northwest of Iran) with 2 km distance from city centre, is one of the natural and continental lakes in Iran. It was created as a result of Shurabil fault activity within the limy hillocks in early Quaternary. This is the type of pluvial lake and has been formed along with argillite interlayers on the synclinal bed with limymarl basement rock. The samples taken from sediments deposited on the surface of the lakebed and investigation of the results from granulometry and chemical analyses indicate that these sediments are actually limy sands carried into the lake as a result of erosion of marls in surrounding hills. On the western coast of the lake, the above mentioned sediments are characterized with clayey sand texture, while towards the eastern side as the presence of clastic materials decreases and granules within the sediments get finer, the texture becomes silty. Lakebed sediments with PH>7, contain 3 – 12% of organic material. The presence of salts, especially calcium carbonate and magnesium in abundance within the clastic materials carried into the lake, has caused the lake water to be excessively saline and being called Shurabil which means "Brine Lake". The studies show that deep into the floor of the lake, on the clastic sediments, a sludge-like thin layer with black color have been formed by the biochemical deposits. Up until the time when the water of Balkhlou-chay River didn’t introduce into the lake and prior to the biological and chemical changes of lake's water, this sediment had been deposited in significant thickness on the entire lakebed and even around it and due to the presence of abundant salts, local people used it as the therapeutic sludge for treatment of some diseases.
