چکیده

زون ماگمایی ارومیه دختر در ایران به عنوان یک کمربند چند فلزی شناخته شده است که دارای سنگ میزبان کانسارهای پورفیری، کانسار اسکارن چند فلزی است.در این تحقیق تحلیل آماری چند متغیره برای شناسایی آنومالی های ژئوشیمیایی مورد توجه است.تحلیل های آنالیز فاکتوری مرحله به مرحله ، آنالیز خوشه ای و مدل فراکتال برای شناسایی آنومالی های عناصری چون طلا،مس، سرب، روی، نقره، مولیبدن، تنگستن، قلع و آرسنیک برای کانسارهای اسکارنی مورد تجزیه و تحلیل قرار گرفت و مشخص شد که کمربند ارومیه -دختر میزبان طلا در این منطقه است. به علاوه مشخص شد که تلفیق روش های آماری و مدل فراکتال ابزار های مناسب برای شناسایی آنومالی های ژئوشیمیایی هستند.
