| Summary:
With this study particually mineralogical, petrographical and petrological characteristics of adakite like acidic porphyries were determined and their origins and geodynamic evolution terms were put forward. The relatively high Rb-Sr and Sm-Nd isotopic composition of the rocks point out that these rocks might belong to lower mantle crust source. When all data were put together, adakite porphyries studied were formed with partial melting of lower crust. It is understood that the melt occurred with partial melting has not been fractionated of substantial degree. Under the light of these information, it can be said that these rocks were developed during the term mentioned above, in an extantional regime following continent-continent collision event. Key Words: Hamsiköy-Trabzon, Adakites, Andesite and Dacite, NE Turkey Mineralogy, Petrography, Petrology
