in taleghan, olivine basalt-basaltic andesite dykes as part of tertiary mamgmatic activities in central and western alborz zone, intruded into both karaj formation and late eocene-oligocene volcanic rocks. these dykes have similar geochemical characteristic which suggest that they are originated from a common source. on the primitive mantle normalized spider diagram, the dykes are characterized...

Feldspar grains, as a significant provenance indicator, of two terrigenous formations from Central Iran, the Upper Red Formation, and Moghan area, Zivah Formation, are used for provenance determination and the study of transportation and depositional history. The Upper Red Formation (URF) is volumetrically the most important siliciclastic unit of the Central Iran and Zivah Formation (ZF) repres...
