Systematic zircon, cassiterite and coltan U-Pb dating, Hf isotope and whole-rock geochemical analysis were undertaken. Two-mica granite and muscovite albite granite have S-type granite affinities and chemical compositions suggesting a post-orogenic setting, and the spodumene pegmatites belong to the LCT (Li-Cs-Ta) group of pegmatites.

Mid-Late Paleocene Alibeyli carbonatites intruded into this stocks as semi cir-cle, arc and small cones in two phases (I) early carbonatite phase and (II) late carbonatite phase. LREE-phosphate phase – britholite, fluorite and apatite were found to be associated with the carbon-atites that accounting for only economic minerals of the area.

Several studies have led to a classification of the base metal sulfide deposits in the Bergslagen ore district into two types, Falun belonging to the so-called "Falun" (Magnusson, 1950, 1953) or "SVALS" (strata-bound volcanic-associated limestone-skarn-hosted) type (Allen et al., 1996).Genetic models for this type of deposit involve leaching of metals from mainly submarine felsic
