Bozkır is an old town established on the skirts of the Taurus Mountains, and contain various tectonic units, eg. Bozkır unit, extending laterally several hundreds of kilometres. The Bozkır unit typically crops out and hence named around Bozkır district. It is formed by deep sea sediments, ophiolites and submarine basic volcanic rocks, all of which overlied by well-exposed Paleogene and Neogene? units. Bozkır is rich not only for its geological occurrence, but also for its culture, history and nature. Bozkır is in a central position of ancient Isauria and represented by Zengibar castle. The town has also a bridge of Seljuk period and various Seljuk and Ottoman Mosques. Çarşamba stream, source of the life in the region, is originated from Taurus Mountains both as Aygır spring, and as leakage from Sarıot lake. It crosses from various villages and town up to Mavi Gorge to meet with the water channel. All of which suggest that Bozkır district should be declared as a Geopark.

The activity concentrations of 222Rn with an AlphaGUARD system in well having different depths and in natural spring waters were measured to assess the natural radioactivity level of the Çorlu region. The measured concentrations varied from 22.04 to 63.92 Bq L−1 for 6 well water samples, 15.38–24.33 Bq L−1 for 6 spring water samples. The activity concentrations from 238U, 232Th and 40K in 11 soil samples collected from the same region were also determined and the outdoor gamma dose rates at 1 m above the surface at the same sampling points were measured. The results obtained in this study lie within safe limits recommended by WHO and UNSCEAR with the exception of the mean specific activity of 40K radionuclide. © 2021, Akadémiai Kiadó, Budapest, Hungary.

This study aims to characterize the mineralogical characteristics and chemical composition of the amphiboles in the metamagmatic sole rocks of the Hatıp Ophiolitic Mélange. The main rock types in the metamorphic sole rocks are amphibolite (amphibole up to 90.3 %); epidote-amphibolite (65.3% amphibole); zoisite-amphibolite (amphibole 52.2%) and amphibole-quartzite (amphibole 28.5%) with nematoblastic to porphyroblastic texture. The microprobe analyses of the amphiboles suggest that the amphiboles have crystallized from a wet magma in medium pressure condition (≤ 7 kb), and are magnesiohornblende, pargasite and edenite in composition. The obtained data also reveal that the Neotethyan assemblage has experienced a regional metamorphism in greenschist facies conditions, which resulted in no chemical changes in the amphiboles., Konya yöresinde Neotetis topluluğu, Geç Kretase yaşlı makaslanmış serpantinit ve harzburgitlerin altında ince dilimler şeklinde metamorfik taban kayaçlarının bulunduğu Hatıp ofiyolitik Melanjı ve Çayırbağı ofiyolitleri ile temsil edilirler. Bu çalışmada, metamorfik dilimde yer alan metamagmatik kayaçlardaki amfibollerin mineralojik özelliklerinin ve kimyasal bileşimlerinin ortaya konulması amaçlanmıştır. Metamorfik dilimdeki ana kayaç tipleri nematoblastik - porfiroblastik dokuya sahip olan amfibolit (% 90.3 lere varan amfibol); epidot amfibolit (%65.3 amfibol); zoisit amfibolit (%52.2 amfibol) ve amfibol kuvarsit (%28.5 amfibol) tir. Amfibollerin kimyası, amfibollerin orta basınç şartlarında (≤ 7 kb) sulu bir mağmadan kristalleşen magnezyohornblend, pargazit ve edenit bileşiminde olduğunu ortaya koymaktadır. Eldeki veriler, ayrıca Neotetis topluluğunun daha sonra amfibollerde kimyasal bir değişiklik oluşturmayan yeşilşist fasiyesi şartlarında bölgesel bir metamorfizmaya uğradığını vurgulamaktadır.

These conditions are strictly controlled by environment and nature of rock varieties (marble and stone). This study is a first approach to understand the relation between some geological features and behavior against salt (Na2SO4) decay of Moroccan marbles and stones. For this purpose, widely used four dolomitic limestones, two crystalline limestones, one limestone and one basalt sample (total 8) were chosen from Morocco. Extra attention paid to choose locations being a representative of all Moroccan country. The carbonate samples (limestone and dolomite) consist of mainly dolomite and calcite with micritic and sparitic cement. The sole, non-carbonaceous sample is basalt of Khenifra containing mainly plagioclase and pyroxene. In general, both bulk-dry and powder density values of the studied rock samples are homogeneous. The limestone of Bir Jdid has the highest (10.81 %) effective porosity and dry weight loss value (4.61 %). The loss on ignition value of the Khenifra basalt has the lowest value with 1.26 %. The loss on ignition values are also relatively uniform. The obtained data indicate that outdoor uses (especially in coastal areas) of limestones of Bir Jdid and dolomitic limestones of Taza are more risky than the others., Hem geçmiş dönemlerde hem de günümüzde çok çeşitli amaçlar için kullanılan doğal taşlar farklı ayrışma, dağılma ve bozunmaya uğramaktadırlar. Bu şartlar çevre ve kayacın türüne (mermer ve taş) sıkı sıkıya bağlıdır. Bu çalışma Fas mermerleri ve taşlarını tuza (Na2SO4) karşı dayanımlarını ve bazı jeolojik özelliklerini anlamak için yapılan ilk çalışmadır. Bunun için Fas’tan getirilen çok kullanılan 4 dolomit, 2 kristalize kireçtaşı, 1 kireçtaşı ve bir bazalt (toplam 8 adet) örneği seçilmiştir. Örnekler mümkün mertebe Fas’ın değişik yerlerinden seçilmiştir. Karbonat kayaçları (kireçtaşı ve dolomit) temel olarak dolomit ve kalsit minerallerinden müteşekkil olup çimento mikrit ve sparittir. Karbonatsız tek kayaç olan Khenifra bazaltı esasen plajiyoklas ve piroksen içerir. Genel olarak örneklerin kuru ve öğütülmüş ağırlıkları birbirlerine benzer. Bir Jdid kireçtaşları en yüksek etkili porozite (% 10.81) ve kuru ağırlık kaybına (%4.61) sahiptir. En düşük ateş zayiatı Khenifra bazaltlarındadır (%1.26). Ateş zayiatları genel olarak homojendir. Eldeki veriler Bir Jdid kireçtaşları ve Taza dolomitik kireçtaşlarının dışarda (özellikle sahil bölgelerinde) kullanımlarının diğerlerine göre daha riskli olduğuna işaret etmektedir.

Turkey has important chromite, magnesite and olivine deposits within peridotite host rocks. The peridotites (harzburgite, verlite, lherzolite and dunite) are mostly serpentinised as a result of metasomatic reaction of olivine and pyroxene minerals with percolating water. The serpentinites are generally an important part of ophiolitic complexes which displays a discontinuous belts all over the country. The chromite deposits are often related to cumulates and tectonites (as Alpine and/or podiform type deposits) and despite their small reserves, their grade can reach up to 58 %. In most deposits, a little enrichment efforts, the grade of chromite can easily be reached from 25 % to 40-45 %.The magnesite deposits of West Anatolia is especially concentrated in three provinces. These provinces are Konya, Kutahya and Eskisehir. The magnesites are of cryptocrystalline type and, like chromite deposits, their reserve are small but have high grade with low FeO-CaO and high MgO ratio. Once again, these deposits are fo...

We examined the rare earth element content of several cryptocrystalline magnesites as well as hydromagnesite, host rock serpentinites, lake water and hot spring water from Turkey. Southwestern Turkey hosts cryptocrystalline magnesites, sedimentary magnesites with presently forming, biologically mediated hydromagnesites and travertines. Our results show the REE content of the minerals, rocks and waters are well below detection limits. One hydromagnesite sample from Lake Salda has slightly high La (2.38ppb), Ce (3.91 ppb) and Nd (1.68 ppb) when compared to other samples, but these are also still below detection limits of the method we followed.

In this study, three type of marble and one granite were chosen to understand if the coating is effective on hardness of the commercial rocks. To understand the hardness of the rock, Schmidt hammer tests were undertaken. The used device allowed us uniaxial compressive strength (UCS) as well as Schmidt rebound (R). The coated samples have clearly high R and UCS values when compared to uncoated samples. The Elazig visne, the well-known marble of Turkey, have 35.6 R and 44.2 MPa UCS values of coated samples. On the other hand, uncoated surface of the same marble have 30.5 R and 35.4 MPa UCS.

Approximately 8% of Turkey is covered by ultramafic rocks which host economically important deposits of magnesite, chromite and olivine. Magnesite deposits are of three types: (1) Massive or crystalline, (2) Cryptocrystalline and (3) Sedimentary. Cryptocrystalline and sedimentary type magnesite deposits are widespread all over Turkey although the massive type deposits are seemingly absent. In this study, we examined the sedimentary magnesite deposits of Hirsizdere, located in the province of Denizli, SW Turkey. The deposits formed as five beds within an ultramafic environment. The thickness of the magnesite beds can reach up to 4 meters and may be traced up to 3 km from west to east. The deposit comprises half a million tons of magnesite with some associated dolomite.

The study area is located at 20 km southwest of Seydişehir (Konya) and the chromites are cropped out in the dunitic rocks of the Kızıldağ ultramafics. The chromites are found as banded, schliren and massive occurrences and their chemical composition have a features of Alpine type chromites. These chromites can be classified as Al- rich and ferric chromites and their Cr/Fet is between 2.77 and 3.28 (mean 2.99). In the Cr/Cr+AlMg/Mg+Fe +2 binary diagram, r/Cr+Al values covers a festricted area while Mg/Mg + Fe+2 ratios distrubuted in a wider range. There is a strong negative correlation between Cr and Mg and negative (not too strong) correlation between Cr and Al., Seydişehir'in yaklaşık 20 km güneybatısında bulunan Kızıldağ'da ortaya çıkan kromitler ultramafik kütlenin dunit bileşimli kayaçları içerisinde bulunmaktadır. Bu kayaçlar içerisinde bandlı, saçılımlı ve masif yapılı olarak bulunan kromitler, kimyasal bakımdan Alpin tip kromitlerin özelliğini taşımaktadır. Al'lu ve Ferri kromit olarak adlandırılan kromitlerin Cr/Fet oranı 2.77 ile 3.28 arasında (ort. 2.92) değişmektedir. Cr/Cr+Al-Mg/Mg+Fe+2diyagramında üç değerlikli bileşenler dar bir alanda iki değerlikli bileşenler ise daha geniş bir alanda dağılım gösterirler.
