Isotope geochemistry of sulfur: implications for origin and distribution of sulfur in Isparta Angle of Western Taurus Belt, SW, Turkey
Abstract
The study area is located between Isparta and Burdur cities in Turkey, with an area of 350 km2
. According
to sulfur isotope (δ34S) data of samples, the calculated δ34S (‰) values are between 0.0447 and 0.0449
and the variation range [Δ(δ34S)] is 7.7. These values suggest a genetic environment that suitable for a
shale formation. When it was examined the volcanic rocks in the region, it has shown that the rocks were
quite poor in point of sulfide ores, but it has been found Triassic bituminous shale, oil seepages in vicinity.
Previous researchers asserted that the sulfur must have been originated from the volcanism. However,
isotopic and geochemical analyses, detailed field surveys of volcanic rocks suggest that the sulfur has
organic origin and may have occurred in a shale environment. It is thought that the sulfur may have been
reached to the surface by hydrothermal water and gas in the end of the volcanism.
