“…Thus, cementation of the amalgamating grains and gravels likely commenced with the precipitation of micritic coatings, followed by pore-filling spary calcites and meniscus bridges. These fabrics, suggestive of intertidal and upper intertidal cements (Vousdoukas et al 2007), are common as various authors which have pinpointed along the Mediterranean coast of Turkey from the Gulf of Iskenderun to the Gulf of Saros (Erol 1972;Bener 1974;Erginal et al 2008Erginal et al , 2010Çiner et al 2009;Desruelles et al 2009), as well as (Erginal 2012;Ertek et al 2015) and, unexpectedly, the Thracian Black Sea coast of Turkey (Erginal et al 2013).…”

On the seaward northwest slopes of Mount Keldağ, Hatay, the combination of an unconformably overlapping sequence of cemented gravels on a wave-cut platform, and a raised notch and irregular pits left by grazing molluscs on the walls of this notch, carved in an NE-trending high-angle fault plane, retain the record of raised braided stream gravels transformed into beachrock. From the OSL ages, this study reveals that deposition of this sequence occurred between 232.30 ± 31.62 and 214.01 ± 27.42 ka during the penultimate interglacial. The four distinct facies identified are massive matrix-supported conglomerate, massive to crudely stratified gravel, cross-stratified gravel, and clast-supported open-work gravel. Extending to the paleo-coastline during the MIS7 highstand, this sequence was cemented by carbonate and iron-oxide cements and records an uplift of around 0.1 mm/year up to the present.

“…Bilindiği üzere, bilgisayar denetimli çoklu elektrot özdirenç ölçüm sistemlerinin gelişimi ve kullanılan ters çözüm algoritmaları, farklı problemler için sığ yeraltı yapılarının araştırılmasında elektrik özdirenç tomografi (EÖT) yöntemini oldukça cazip hale getirmiştir [3][4][5][6][7][8]. Gerçekleştirilen ölçümler iki-veya üç-boyutlu olarak çok kısa sürede tamamlanabilmekte ve başarılı sonuçlar alınabilmektedir.…”

ÖzetBu çalışmada, jeofizik ölçümlerden elde edilen sayısal verilerin ortogonal dilimler kullanarak üç-boyutlu hacimsel görüntülenebilmesi için geliştirilen basit bir algoritma sunulmuştur. Bu algoritma doğru akım özdirenç (DAÖ) yöntemi ile sığ derinlikte gömülü kuramsal modellerin tepkisini sunmak için kullanılmıştır. Kuramsal görünür özdirenç verileri iki-boyutlu ters çözüm tekniğiyle değerlendirilmiş ve yer elektrik kesitler elde edilmiştir. Sonuçlar, birbirlerinden bağımsız paralel hatlara ait iki-boyutlu yer elektrik kesitlerin bir araya getirilmesi ile oluşturulan üç-boyutlu hacimsel görünümlerle sunulmuş ve model yapılara ait belirtilerin hem düşey hem de yanal yöndeki sürekliliklerinin tek bir şekil üzerinde kolaylıkla izlenebilmesi sağlanmıştır. Ayrıca, geliştirilen algoritma farklı ortamlarda farklı problemler için gerçekleştirilmiş DAÖ çalışmalarında elde edilen verilerin değerlendirilmesinde de kullanılmış ve yorumlamaya katkı sağlayan bu hacimsel görüntüler sunulmuştur.Anahtar Kelimeler: Algoritma, ortogonal dilimler, doğru akım özdirenç (DAÖ), üç-boyutlu görüntüleme Application of Three-dimensional Visualization Techniques to Electrical Resistivity Tomography Data Using New Generation Software Packages AbstractIn this study, an algorithm that was developed for three-dimensional volumetric visualization of numerical data sets obtained from geophysical measurements by using orthogonal slices is presented. This algorithm was used for the presentation of the response of shallow synthetic models using direct current resistivity (DCR) method. Synthetic apparent resistivities were processed by two-dimensional inversion scheme and inverse model resistivity sections were obtained. The results were presented by three-dimensional volumetric sections produced from twodimensional inverse model resistivity sections of parallel profiles, and horizontal and vertical continuities of the anomalies of model bodies were easily demonstrated on a single figure. Additionally, the developed algorithm was used to evaluate DCR data sets which were obtained from various investigations in different areas, and the resultant volumetric images contributing to the interpretations were presented.

“…De spite the dif fer ent ce men ta tion pro cesses and prod ucts, there is one com mon im por tant fac tor in beachrock for ma tion; ce men ta tion com monly oc curs within the intertidal zone (Bricker, 1971;Spurgeon et al, 2003). Beachrocks have been ex ten sively stud ied in many re gions in the world, such as on the coast of the Red Sea (e.g., Holail and Rashed, 1992;Ghandour et al, 2014), the Black Sea (Erginal et al, 2012(Erginal et al, , 2013, Florida (e.g., Spurgeon et al, 2003), the Med i ter ra nean (e.g., Alexandersson, 1972;El-Sayed, 1988), Cen tral Amer ica and the Ca rib bean (e.g., Beier, 1985), In dia (Kumar et al, 2000(Kumar et al, , 2012, the Ara bian Gulf (e.g.,Tay lor and Illing, 1971), Ha waii (Meyers, 1987), Aus tra lia (e.g., Chivas et al, 1986) and Scot land (e.g., Kneale and Viles, 2000).

Un rav el ing ce men ta tion en vi ron ment and pat terns of Ho lo cene beachrocks in the Ara bian Gulf and the Gulf of Aqaba: sta ble iso tope ap proach. Geo log i cal Quar terly, 58 (2): 207-216, doi: 10.7306/gq.1144 This pa per anal y ses Ho lo cene beachrocks from the Ara bian Gulf and the Gulf of Aqaba to ex plain the mech a nisms that in fluence the ce men ta tion pro cess in these ar eas. Ho lo cene beachrocks in the Gulf of Aqaba are com posed of pre dom i nantly terrigenous ma te rial de rived from ero sion of ad ja cent up lifted Pre cam brian base ment, while the beachrocks in the Ara bian Gulf are com posed mainly of ma rine bioclasts and wind-blown siliciclastic sands. The ce ments of beachrocks in both ar eas show three tex tural va ri et ies: (1) isopachous phreatic acicular ar agon ite; (2) a micritic en ve lope of high-Mg cal cite (HMC); (3) meniscus and grav i ta tional vadose HMC. Ra dio car bon dat ing of beachrock sam ples from the Ara bian Gulf yielded ages from ca. 2300 to 660 yr cal BP whereas sam ples from the Gulf of Aqaba range in age be tween 5500 and 2800 yr cal BP. Ox y gen iso tope val ues range from 2.6 to 4.4‰ re spec tively for the Ara bian Gulf whereas the Gulf of Aqaba val ues range from 1.2 to 1.5‰. Car bon iso tope val ues range from 3.2 to 5.9‰ for the Ara bian Gulf whereas those from the Gulf of Aqaba range from 3.8 to 4.6‰. The val ues of d 18 O VPDB and d 13 C VPDB in the beachrocks of both ar eas sug gest a ma rine or i gin. The beachrocks of the Ara bian Gulf were pre cip i tated un der high evap o ra tion con di tions, while beachrocks from the Gulf of Aqaba were pre cip itated in nor mal shal low-ma rine con di tions. The min er al ogy and tex tural hab its sug gest that ce men ta tion of these beachrocks started within the shal low-ma rine phreatic zone.
