“…Sampling and analytical procedures 3.1. U-series dating Dating of travertine and associated carbonate veins is important because it places constraints on the timing of tectonic and palaeoseismic activity (Hancock et al 1999;Temiz et al, 2013;Uysal et al, 2007Uysal et al, , 2009 carrier was added. In order to concentrate the U and Th elements from the bulk solution, a Fe(OH) 3 precipitate was created by adding a solution of ammonium hydroxide until obtaining a pH between 7 and 9.…”

“…In contrast, travertine precipitation along major strike-slip fault zones is less common, being restricted to pressure ridges, releasing/restraining bends and the intersection of the normal faults that encircle some part of strike-slip basin, as in the western end of the Bolu Basin, the NAFS, NW Turkey (Gökten et al, 2011;Temiz et al, 2013).…”

“…In previous studies, U-series age data obtained from travertine deposits, and particularly from vein travertines (or vertically banded travertines) have been used for some neotectonic interpretations such as the calculation of dilation in fisssure ridges, the lateral propagation along the length of travertine-filled fissures (Altunel & Hancock, 1993a, 1993bAltunel & Karabacak, 2005;Hancock et al, 1999;Mesci et al, 2008) to determine fault activity (Brogi et al, 2012;Temiz et al, 2013) and seismicity (Uysal et al, 2009(Uysal et al, , 2011. In geothermal fields, circulation and upwelling of hydrothermal fluids and consequently travertine precipitation become easy during faulting and fracturing periods (Brogi & Capezzuoli, 2009).…”

“…With a few notable exceptions (Faccenna et al, 2008;Temiz, Gökten, & Eikenberg, 2013), studies on travertines that are located along (major) strike-slip fault zones are limited. The Tivoli travertine, situated about 25 km east of Rome, Central Italy (Chafetz & Folk, 1984), is one of the best examples related to strike-slip faulting (Faccenna et al, 2008).…”

“…Travertine formation along the western sector of the North Anatolian Fault System (NAFS), i.e. a major right-lateral strike-slip fault system in Turkey, occurred on pressure ridges, releasing/restraining bends, and around the intersections of different trending normal faults that bound the western end of the Bolu Basin (Temiz et al, 2013).…”

Travertine occurrences along major strike-slip fault zones: structural, depositional and geochemical constraints from the Eastern Anatolian Fault System (EAFS), Turkey

et al. 2015

The Eastern Anatolian Fault System (EAFS) is a left-lateral strike-slip fault zone, 30 km wide and 700 km long, that is the second most important neotectonic structure of Turkey. In this study, relationship between travertine precipitation and tectonic activity of some segments along this major strike-slip fault zone has been investigated by a multidisciplinary research. Structural, sedimentological, geochemical and geochronological studies were conducted on several travertine occurrences along the Karlıova-Bingöl segment (KBS) and the Adıyaman Fault Zone (AFZ) of the EAFS. The Baltaşı travertine mass on the AFZ was cross-cut by many extensional fractures that were filled by calcite veins. Geochemical analyses of the calcite veins indicate that some are hydrothermal in origin, whereas others are non-hydrothermal. Hydrothermal circulation in the crust was caused intermittently by the left-lateral strike-slip movements that have oblique-to normal-slip components in both the (KBS) and the (BYS) segments. Our results suggest that, from at least 325 ka until present, tectonic activity was consistently accompanied by travertine deposition. Based on dating of the travertine occurrences in the valley of the Göynük Stream around Hacılar and Elmalı, it is concluded that the NE-trending KBS is currently still active.

The implications of fault zone transformation on aseismic creep: Example of the North Anatolian Fault, Turkey

et al. 2017

Aseismic creep is observed at surface along several segments of the North Anatolian right‐lateral active fault in Turkey, a major plate boundary between Eurasia and Anatolia. Identifying the mechanisms that control creep and their temporal and spatial change represents a major challenge for predicting the mechanical evolution of active faults, the interplay between creep and earthquakes, and the link between short‐term observations from geodesy and the long‐term fault zone evolution. We combine geological observations, laboratory analyses, and imaging techniques, shedding new light on the mechanism of fault creep along the North Anatolian Fault (NAF) and its time‐dependent change. A clear correlation is shown between shallow creep and near‐surface fault gouge composition: locked segments of the NAF are mostly composed of massive limestones without clay gouges, whereas creeping segments comprise clay gouges that contain low‐friction minerals. Such fault gouges appear to result from a progressive change of initial volcanic host rocks during their deformation. Anastomosing cleavage develops during the first stage of displacement, leading to layering, oblique at first and then subparallel to the fault, which accommodates part of the aseismic creep by pressure solution. Soluble minerals are dissolved, leading to passive concentration of phyllosilicates in the gouges where alteration transformations by fluid flow produce low friction minerals. At the same time damage zones are fractured and fractures are sealed by carbonates. As a result, these mineralogical and structural transformations weaken the gouge and strengthen the damage zone leading to the change from diffuse to localized seismic‐aseismic zones.
