Bu çalışmada, Eşme İlçesinde (Uşak) yeralan Güneyköy’de Paleozoik yaşlı granitik gnayslarda bulunan Au-içeren arsenopiritli kuvars damarlarında gelişen skoroditleşmenin mineralojik-petrografik özellikleri ile Au-skoroditleşme ilişkisi incelenmiştir. Çalışma alanında başlıca en yaygın olan cevher minerali arsenopirittir. Arsenopiritler kenar ve dilinimleri boyunca skorodite dönüşmüştür. Yaptırılan jeokimyasal analizlere göre arsenopiritlerin Au içeriği 0,5 ppm ile 10 ppm aralığında değiştiği belirlenmiştir. Arsenopiritlerde mikroskobik olarak görülebilir Au olmamasına rağmen arsenopiritin alterasyon ürünü olan skoroditte ise mikroskobik olarak 30-100 mµ boytunda Au taneleri olduğu belirlenmiştir. Arsenopirit ve arsenopiritte yeralan Au hipojen olarak oluşurken, arsenopiritin alterasyonu sürecinde, oluşan skorodit ile skoroditteki Au birikmesi ise süperjen oluşum olarak tanımlanmıştır.
