Abstract
The Hallaçlar formation of Upper Oligocene-Lower Miocene age is the oldest unit of the area. The volcanics of this formation are affected by widespread hydrothermal alteration. The Dedetepe formation, of Lower Miocene age, unconformably overlies the Hallaçlar formation and is characterized by andesitic lavas, tuffs and aglomerates which are not affected by the hydrothermal alterations. Soma formation (Middle Miocene-Lower Pliocene in age) consists of claystones, marls, dolomites and limestones unconformably overlying the volcanics. This sequence is overlain by the Quaternary alluvium. The volcanics of Hallaçlar formation, displaying various colors as a result of the hydrothermal alteration, are divided into the units of unaltered and altered volcanics. Altered volcanics are further divided, according to the degree of alteration, into the four subunits of slightly altered volcanics, argillic, silicified and sulfidic zones. As the result of chemical analyses, it is concluded that epithermal trace element enrichments are localizied only in the Hallaçlar formation. Au, Ag, Cu, Pb, Mo, As, and Hg anomalies are determined in extensively silicified zones. It has been concluded that the silicified zones of the Hallaçlar formation seem to have a potential for precious metal mineralization.
