| 英文摘要 | Petrological, geochemical and zircon U-Pb and Hf isotope studies were carried out on the Hajseyran pluton, along the Tarom-Hashtjin metallogenic zone, as part of the Alborz-Azerbaijan magmatic belt, which is located in the central part of the Alpine-Himalayan orogenic belt. The Hajseyran pluton, which is made up of syenite, monzonite, quartz-monzonite and granite, yields a zircon U-Pb age of 39.20 +/- 0.56 Ma (for a quartz-monzonite sample) with shoshonitic features. Enrichment in large ion lithophile elements, depletion in high-field-strength elements and negative anomalies of Nb, Ta and Ti in Chomalou samples suggest a subduction-related arc magmatic setting. The Chomalou epithermal Pb-Zn-Cu deposit occurs close to the Hajseyran pluton with the quartz-base metal sulfide veins predominantly hosted by Eocene volcanic rocks. The ore-forming processes include chalcopyrite and sphalerite-galena formation, with the latter the major mineralisation in this region. Microthermometric results from the liquid-vapour fluid-inclusion assemblages show that the homogenisation temperatures in the first-stage quartz range from 230 to 310 degrees C, in the sphalerite and second-stage quartz from 161 to 293 degrees C and in the late-stage quartz from 175 to 262 degrees C. The salinities of fluids decrease from early-stage quartz to late-stage quartz. The calculated stable isotope values of ore-fluid components (delta O-18(water) = +3.28 parts per thousand to -3.68 parts per thousand; delta S-34(H2S) = +5.5 parts per thousand to +7.8 parts per thousand) show that magmatic fluids have played a significant role during mineralisation. The Chomalou deposit is interpreted as a volcanic-hosted intermediate-sulfidation type of epithermal mineralisation formed through shallow-level emplacement of the Hajseyran pluton, which formed via partial melting of phlogopite-amphibole-bearing sub-continental lithospheric mantle. The Neotethyan slab roll-back and concomitant asthenospheric upwelling led to the decompression melting of metasomatised sub-continental lithospheric mantle and the formation of several K-rich plutons and associated epithermal deposits in the Alborz-Azerbaijan magmatic belt. |
