Abstract

Sungun and HAFTCHESHME mines are located in the Arasbaran volcano-plutonic complex at the North West of Azarbaijan province. Lamprophyric dikes of SUNGUN with ages younger than Oligo-Miocene contain biotite, plagioclase and pyroxene with porphyritic texture and are classified as calc-alkaline and KERSANTITE. They are intruded into the SUNGUN quartz - monzonite. Lamprophyric dikes of HAFTCHESHME with ages younger than Oligo-Miocene include minerals such asbiotite, alkali feldspar and pyroxene. The main textures are microlithic porphyry and flow texture. These CALC-ALKALINE LAMPROPHYREs are classified as MINETTE, intruding the HAFTCHESHME quartz - diorite. The behavior of trace elements studied by the means of spider diagrams show low enrichment of LREE relative to MREE and HREE. Investigations on geochemical characteristics of the studied lamprophyres show that the lamprophyric rocks are of calc-alkaline type, formed in a magmatic arc tectonic setting. These lamprophyres are generated from low degree partial melting of a garnet lherzolite source.
