salafchegan-khorhe volcanic rocks are exposed within urumieh-dokhtar magmatic belt. different kinds of volcanic and subvolcanic rocks of calc-alkaline to alkaline character have been reported throughout this magmatic belt. since, isotopic investigations are very useful for detection of magma petrogenesis and because no isotopic studies have been done in this area, so a geochemical and isotopic ...

Ab&r&-Sulphur isotope abundances of thirty-nine specimens of seventeen meteorites are reported. The resultril show again the remarkable constancy of the sulphur isotope ratios for meteorites of all types. However, differences in the SBa/Sa* ratios of 0.4 %a would appear to be significant. The Ssz/P4 ratio for meteorites is discussed as a possible base level from which fr~tion&tion in the earth’...
