Özet

The study area lies in the Klada province of western Turkey. The site has an approximate dimension of 1.5 to 2km north-south length and 3km east-west width. Combined methods from the fields of geology, geochemistry and geophysics were applied to elucidate the regional geologic framework and identify favorable environs for mineralization. There are a few volcanic hills in the center of the Klada caldera, which is actually a field of interest. Magnetics (M), Magnetic Total Field Gradient (Mg), Radiometry (Ra), Microgravity (MG) and Microgravity Gradient (MGG) methods were used to prospect the terrains and boundaries of gold and silver deposition in the area. The observed mineralized zones are characterized by low magnetization, low radiation, and high density contrast. Such zones appear to exist outside and beneath a magnetized cap rock. The locations of proposed drill holes were determined with varying depths. Following completion of geophysical and geochemical exploration, an open cut mine with a yearly production rate of about 5 to 6 tons of gold minerals at depths varying between 50 to 225m has been operational.
