ABSTRACT: There are important travertine deposits in the eastern Black Sea Region, especially in Bayburt,Gümüşhane and Şiran. In the region, production of natural stones has been increased in the last decadeand production of travertine reached to 450 millions tons in 2003. Traverten formations are controlledwith NE-SW directed fault systems crosscutting NAF. In this study, physico-mechanical properties andformation condition of Bahçecik travertine as the biggest travertine deposit in the region weredetermined.Bahçecik travertine was formed with carbonic acid-rich water percolated through rocks in limestone,the water dissolved the Berdiga limestones and becomes saturated with it. When the water resurfacedrelated with vertical faults, the sudden drop in pressure caused the water to release thegas and the calcium carbonate then recrystallized. Widely outcropping terraced-mount type travertine was formed by saturated water resurfaced on the low slopes topographical surface. Considering to itsmorphological properties and formation condition, reserve of terraced-mount type Bahçecik travertineis about 400000 m .Determination of uniaxial compressive strength of intact rocks can be quite difficult owing to timeconsuming and expensive to prepare specimens and to conduct this test. Thus, if there is a linearcorrelation between strength and index properties of travertine samples is tested. As a result of this study,it is concluded that there is a linear correlation between uniaxial compressive strength and sonic velocitytest results.
