Özet:

 Malachite Cu2CO3 OH2 and azurite Cu3CO32OH2 minerals were observed in the Mersin ophiolite, which was tectonically settled in the region in the Upper Cretaceous, around Musalı village in Mersin province. Blue and green colored azurmalachites are found as veins in the cracks and pore spaces of the altered gabbro host rock.In the thin section examination of the host rock sample, which consists of plagioclase and clinopyroxene minerals and presents a granular texture, gabro was determined that proxenes turned into amphiboles, intense opacification and epidotization-chloritization. According to the X-Ray Diffraction XRD analysis results, pyrite, chalcopyrite, azurite, malachite, pyroxene and amphibole minerals were found in the samples taken. According to the X-Ray Fluorescence XRF analysis results of azurite and malachite dense samples, the determined values of the amount of SiO2 are 31, the amount of Al2O3 is 15.7 - 19.2, the amount of CaO is 19.3 - 20.8, the amount of Fe2O3 is 13.4 - 8.8, Cu amount 7.09 - 9.19, S amount 3.94 - 3.15. According to ICP-MS results, it was observed that the amount of Cu was above 50000 ppm, while the ppm amount of V, Cr, Sr, Ni, Co was higher than other elements.In order to measure the gemological value of Azurmalachites, slices were taken and many geometric and amorphous forms were given, and flat or cabochon shapes were made. Mineralogical examinations, the blue-green colored minerals found in Mersin-Musalı were determined to be azurmalachite and were suitable for the production of ornamental stones or ornamental objects with their visually attractive color, and the shaped samples were combined with metal and jewelery applications were made.

 Malahit Cu2CO3 OH2 ve azurit Cu3CO32OH2 mineralleri Mersin iline bağlı Musalı köyü civarında Üst Kretasede tektonik olarak bölgeye yerleşen Mersin ofiyoliti içerisinde gözlemlenmiştir. Altere olmuş gabro yan kayacının çatlak ve gözenek boşluklarında mavi ve yeşil renkli azurmalahitler, damarlar halinde bulunmaktadır. Plajiyoklaz ile klinopiroksen minerallerinden oluşan ve taneli bir doku sunan gabro türü yan kayaç örneğinin ince kesit incelemelerinde piroksenlerin amfibollere dönüştüğü, opaklaşmanın yoğun olduğu ve epidotlaşma  kloritleşmeler türü bozunmaların varlığı tespit edilmiştir. X Işınları Kırınım XRD analiz sonuçlarına göre alınan örneklerde pirit, kalkopirit, azurit, malahit, piroksen ve amfibol minerallerine rastlanmıştır. X-Işını Floresansı XRF analizlerinde SiO2 miktarının azurit ve malahit yoğunluklu örneklerde 31 civarında olduğu gözlemlenirken, Al2O3 miktarının 15.7-19.2, CaO miktarının 19.3-20.8, Fe2O3 miktarıın 13.4-8.8, Cu miktarının 7.09-9.19, S miktarının 3.94-3.15 değerleri arasında olduğu tespit edilmiştir. ICP-MS sonuçlarına göre Cu miktarının 50000 ppmin üzerinde olduğu saptanırken, V, Cr, Sr, Ni, Coın ppm miktarının diğer elementlere göre daha yüksek değerde olduğu gözlemlenmiştir Azurmalahitlerin gemolojik açıdan değelendirilebilirliğini ölçmek için dilimler alınarak çok sayıda geometrik ve serbest formlar verilerek, düz ya da kabaşon şekillendirmeler yapılmıştır. Mersin-Musalıda bulunan mavi yeşil renkli minerallerin mineralojik incelemeler neticesinde azurmalahit olduğu ve görsel olarak cezbedici rengiyle süs taşı veya süs objesi üretimine uygun olduğu belirlenmiş, şekillendirilen örnekler metalle birleştirilerek takı uygulamaları yapılmıştır.
