Abstract

Sungun and Haftcheshme mines located in Arasbaran volcano-plutonic complex in the North West of Azarbaijan province. lamprophyric dikes of Sungun with younger age  Oligo-Miocene including minerals, biotite, plagioclase and pyroxene, porphyritic texture, classified part of the calc-alkaline and kersantite and The area lamprophyric rocks are intruded in to Sungun quartz - monzonite. lamprophyric dikes of haftcheshme with with younger age  Oligo-Miocene including minerals, biotite, alkali feldspar and pyroxene, the main textures microlitic porphyy and flow, Calc-alkaline Lamprophyre component - are classified minette and The area lamprophyric rocks are intruded in to 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. Review geochemical characteristics of the study show that the origin of mantle-derived magmas essentially lamprophyres. The lamprophyric rocks are generated from calc-alkaline lamprophyrecomponent, related to magmatic arc tectonic setting and these lamprophyres  have  gneated from lamprophyre low degree of partial melting of garnet lherzolite.
