“…The Cretaceous to Palaeogene sedimentary successions that are exposed on the Arabian continental margin provide valuable insights into sedimentary evolution, and record details of tectonic processes that affected the southern Neo‐Tethys and the north of the AP. The researches of porphyry tract, ophiolites, and the magmatism in eastern Iran, eastern Turkey, Lesser Caucasus and other parts of the northern Arabian continent indicate a significant subduction‐related continental arc development and collision processes in the Late Cretaceous‐Palaeocene interval (Özer et al, 2017; Pirnia et al, 2020; Saccani et al, 2018; Zürcher et al, 2019). The subsequent Tertiary uplift of the AP as a result of its collision with Eurasia gave rise to significant deposition in the Late Cretaceous to Palaeogene (Bar et al, 2016).…”

In the northernmost AP, deposition began with Aptian-Early Campanian shelf carbonates, followed by deepening turbidites accumulation during the Mid-Campanian in response to regional faulting and tilting (Robertson et al, 2016).…”

The Late Cretaceous sediments on the margin of the Arabia Plate contain information of tectonics and eustatic fluctuation of the Neo‐Tethys Ocean. The sedimentary association in the north of Saudi Arabia, combined with that from Jordan, Israel, and Egypt, revealed three fourth‐order sedimentary sequences that occurred in the Late Cretaceous and Palaeogene. The evolution of the sequences indicates that a most extensive transgression occurred in the south of Neo‐Tethys Ocean during that time, which deposited phosphorite and carbonate overlying the Devonian sandstone directly. The occurrence of thin and interbedded lithological layers implies vigorous fluctuation of the sea‐level during the transgression. We argue that the transgression is the results of tectonic activities and eustatic fluctuation, but may be closely controlled by the regional subduction and Neo‐Tethys collision.

The Lycian nappes lying on top of the para-autochthonous metamorphosed Menderes and unmetamorphosed Bey Dağları successions in SW Anatolia belong to the Tauride segment of the Anatolide-Tauride Block. The Tavas nappe is one of several nappe slices of the Lycian nappes and forms structurally the lowermost tectono-stratigraphic unit. The upper part of the Tavas nappe succession is represented by planktonic foraminifera-bearing uppermost Cretaceous cherty micritic limestones and calciturbidites of the Babadağ Formation and Lower Palaeogene micritic limestones and calciclastic rocks of the Faralya Formation in the study area. Lithostratigraphic characteristics and planktonic foraminiferal assemblages of the two formations in the Bozburun hill locality (S of Köyceğiz) are documented for the first time in three stratigraphic sections in this study. The uppermost part of the Babadağ Formation mainly comprises of alternating calciclastic and micritic limestones, which include diverse planktonic foraminiferal assemblages of mainly keeled morphotypes. The presence of Racemiguembelina fructicosa and Abathomphalus mayaroensis within the assemblages indicates a late Maastrichtian age for the uppermost part of the succession. Two sections of the overlying Faralya Formation comprise mainly planktonic foraminifera-bearing laminated micritic limestones, brecciated limestones and mudstones. Planktonic foraminiferal assemblages of the laminated micritic limestones are dominated by keeled Late Palaeocene morphotypes. The occurrence of Morozovella acuta and Globanomalina planoconica at the base of two sections suggests a Thanetian age for the deposits. The boundary between the Babadağ and Faralya formations is characterized by a stratigraphic gap ranging from the latest Maastrichtian to the earliest Selandian. The gap was linked with the first of the three main events, when ophiolite obduction and incorporation of the Köyceğiz Thrust Sheet into the Lycian allochthon occured. Cretaceous limestone clasts and foraminifers within the Thanetian calciclastic rocks of the Faralya Formation could be clues to that exposure and erosion.

“…The study area is mostly covered with the Lycian Nappes, lied between the Menderes Massif and the Bey Dağları Autochthon (Figure 1b). The Lycian Nappes consists of thrust sheets (nappes piles) of Paleozoic-Cenozoic rocks, ophiolitic and tectonic melanges and serpantinized peridodites (Collins and Robertson, 1997;Özer et al, 2017). The Lycian allochthon is thrust over autochthonous, unmetamorphosed, platform sediments of the Bey Dağları unit (Collins and Robertson, 1998).…”

The estimation of the variation of the b-value, which is frequency distribution of a magnitude given in an earthquake data set of any region, is important parameter for interpretation of tectonic mechanism and seismic hazard assessment of that region. There is an inverse correlation between stress and b-value. The magnitudefrequency relationship is described by the well-known the Gutenberg-Richter relationship. The purpose of this paper is to investigate the recent seismicity of the region between the Bodrum and Fethiye, the south-western Anatolia in Turkey. A total of 27357 earthquake data is taken into account in this study in the period between 2004 to 2020 with magnitude (Ml) larger than 2. The majority of focal depths of earthquakes are concentrated between 0 and 33 km. The b-value in the Gutenberg-Richter relationship was estimated by the maximum likelihood method in this study. The estimated b-values range between 0.5 and 2 in the study region. While the lower b-values (0.5-1) are located at the SE of the study area (mainly the Beydağları unit), higher values (1-2) are trending on the west-east direction along the fault zones. The highest b-values in the study area are possibly related with the brittle lower-mid crust, thermal regime, normal faults and young basins bounded by these faults.
