  Identification of chrysotile in local soil at Beypinari village (Sivas-Turkey) regarding mine and health issue

  Asbestos is dangerous for health and is forbidden to use in Turkey, but villagers who live in rural eastern part still use it especially for their home for insulation purposes and even as a substitute for baby powder. Therefore, geological and chemical properties of this type of soil, which is near the settlement, should be characterized and identified from the point of view of health. Beypinari asbestos deposits are located at Beypinari village, about 90 km southeast of Sivas, Turkey within Central Anatolian Ophiolites. Therefore, in the present study, the existence of chrysotile in Beypinari asbestos deposit were characterized and identified by mineralogical analysis and by major, trace, REE analysis. The results show that the samples contain different amount of calcite mineral, the main mineral being chrysotile.

  207Pb-206Pb, 40Ar-39Ar and Apatite Fission-Track Geothermochronology Revealing the Emplacement, Cooling and Exhumation History of the Karacayir Syenite (N Sivas), East-Central Anatolia, Turkey

  Boztug, Durmus; Türksever, Esra; Heizler, Matt; Jonckheere, Raymond C.; Tichomirowa, Marion

  The Karacayir syenite, intruding the Palaeozoic crustal metamorphics and unconformably overlain by Upper Paleocene to Eocene Tokus formation in the north of Sivas (east-central Anatolia), has been studied with respect to Pb-207-Pb-206 single zircon evaporation, biotite 40Ar-39Ar, and apatite fission-track geothermochronology. Pb-207-Pb-206 single zircon evaporation dating yields an age of 99.0 +/- 11.0 Ma (Cenomanian-Turonian) which is considered to be the intrusion age. Biotite 40Ar-39Ar age determination gives a cooling age of ca. 65 Ma. Apatite fission-track dating, combined with T-t modeling based on track-length distribution data, determines a fast tectonic exhumation with an uplift rate of > 1 mm/a which occurred 58-61 Ma ago. This Middle Paleocene fast tectonic uplift is considered to have resulted from a compressional regime induced by the collision between the Tauride-Anatolide platform (TAP) and the Eurasian plate (EP) along the Izmir-Ankara-Erzincan (IAE) suture zone following the closure of the north-dipping subducted IAE ocean which belongs to northern Neo-Tethyan realm. This compressional regime has also formed the peripheral foreland basins in central Anatolia.
