Explorational studies on the granitic and soft building stones in the Ardebil province
This study carried out in the three fourth area of the province, i.e. central and northern portions. Considering the previous exploration in past years, the crystalline limestone or marble at NW of Namin to Razi, Iman intrusive rock at NW of Meshkinshar, dark andesites of Aqamorad, olivine basaltic dykes of Bayram and Nir travertines are among the existing building stones.
During the prospection, five intrusive bodies, 10 andesitic and basaltic volcanic exposures, two marble occurrences, three travertine deposits, two basic dykes and two crushed stone occurrences were visited and sampled.
In the preliminary exploration, Iman granodiorite, Nurikandi ignimbrite, Moshiran tephrite, Chapouqan ignimbrite, Aqamorad andesite-basalt, and two dykes were studied in more detailed, of which for four occurrences geology map and cross section were prepared on the scale 1:5000.
Based on the performed study, the Iman granodiorite, Nurikandi ignimbrite, Aqamorad andesite-basalt and Bayram dyke are favorable deposits for building stone.
