“…It could be explained by the developing of new fault in the middle part of the Başkale basin or consequence of kinematics changes of the master fault. The trends of long axis of Quaternary travertine ridges in the Lake Urmia area (Mohajjel & Taghipour, 2014), located immediately to east of our study area represent strong similarities with those observed in the Başkale basin. The Çamlık travertines contain three different FRT systems, with variable widths of travertines within the central fissures.…”

“…The extension directions have been determined from the orientation of fibres existing in the banded travertines of vertical fractures (Mohajjel & Taghipour, 2014). Therefore, it is a good indicator for regional extension direction (Altunel & Hancock, 1993a;Altunel & Karabacak, 2005;Çakır, 1999;Mesci et al, 2013;Mohajjel & Taghipour, 2014). The FRTs within the central fissures are partially filled with banded travertines with NW-SE orientations (Figure 4(b)).…”

Fissure-ridge travertines (FRTs) are of great importance for the determination and comparison of tectonic deformation in a region. The coeval development of these travertines with active fault zones supplies significant information about regional dynamics in terms of deformation pattern and evolution. In this paper, the characteristics of FRTs of the Başkale basin (eastern Turkey) and responsible regional tectonism are discussed for the first time. The Başkale basin is located between the Başkale Fault Zone (BFZ) characterised by Çamlık fault and Işıklı-Ziraniş fault. It is located between dextral Yüksekova Fault Zone and southern end of dextral Guilato-Siahcheshmeh-Khoy Fault system (Iran). Various morphological features indicating recent activity are exposed along the BFZ, including offsetting rivers, fissure-ridge travertine and fault scarps. The Çamlık fissure-ridge travertine composing of three different depositions is observed along the eastern edge of the BFZ with approximately parallel orientations. The Çamlık fissure-ridge travertine has been formed and developed on fault zone related to strike-slip or oblique movements. We explain how kinematic changes of faults can influence the fissure-ridge development.

“…In extensional and transtensional provinces, the faults and associated fissures served as natural conduits for the emerging thermal waters. Fissure ridges are elongated, wedge-like structures that formed as ridge travertine was precipitated from the thermal waters that ascended along a fracture or fault plane (Altunel and Hancock, 1993c;Öztekin Okan, 2004;Dilsiz, 2006;Öztekin Okan et al, 2008;Brogi and Capezzuoli, 2009;Temiz et al, 2013;Brogi et al, 2014a;Mohajjel and Taghipour, 2014).…”

IntroductionTravertine deposits located 24 km northwest of Karakoçan (Elazığ) and 60 km southwest of Mazgirt (Tunceli) (Figures 1a and 1b) are on the Karakoçan Fault Zone (KFZ) and Pamuklu Fault Zone (PFZ) and segments of the faults. The terms 'travertine' and 'carbonate tufa' are often used indiscriminately. 'Travertine' is frequently used to refer to carbonate rocks formed from thermal water deposits on the earth's surface, forming various deposit morphologies such as cascades, apron and channel travertines, fissure ridges, plateaus, and towers (Pedley, 2009;Pedley and Rogerson, 2010;Fouke, 2011). According to Andrews (2006) and Capezzuoli et al. (2014), tufas are terrestrial carbonates that form under surficial open-air conditions in streams, rivers, and lakes. Tufa is a product of physicochemical and microbiological biomediation processes. Because tufas form under exposure to light, they contain microbial (bacterial and cyanobacterial) and sometimes other algal components; many tufas encrust higher plants that live on the margins of streams, waterfalls, and wetlands (Pentecost et al., 1997). Tufa carbonates precipitate at ambient temperature from the calcium-bicarbonate waters derived from the dissolution of carbonate bedrock. Travertines are freshwater carbonates precipitated by organic or inorganic processes from the resources of calcium-and bicarbonaterich underground waters (Guo and Riding, 1998). Rapid travertine precipitation initiates when the CO 2 gas within the outcropping waters is emitted to the atmosphere. These freshwater carbonates have an internal structure that frequently changes laterally and vertically. Many conditions, such as differences in the lateral and vertical facies, the position of the resource, the base topography, fluctuations in the amount of the waters storing travertine, and changes in the flow rate and direction of water, organic activities, and surface waters, are frequently encountered in travertine fields due to seasonal climatic factors and tectonic zones. Topography plays a determinative role in the development of facies and in the storing of travertines. The climatic changes' influence on algal growth and travertine precipitation, besides tectonic settings, may produce a significant effect on depositional geometry of the hydrothermal travertine formation.
