In this study, we investigate chemical and isotopic characteristics of low-temperature geothermal waters issuing from carbonate reservoirs in the Çürüksu Graben within eastern termination Büyük Menderes western Turkey. Temperatures pH values vary 20.1 to 24.6 °C 6.62 7.11 those cold are 17.1 19.9 6.85 7.72, respectively. Geothermal Ca-HCO3 Ca-SO4 types whereas characterized by these two Mg-HCO3...
This work presents the chronology of Holocene filling Guadalentín Tectonic Depression (Murcia, SE Spain) combining 14C and OSL age data. studies sediments paleosols interbedded in sedimentary sequence between Totana Librilla, using as reference Espuña Karting section (Alhama de Murcia), which has been fully sampled for its geochronological analysis. The entire dated sequences record last c. 20–...
Terrestrial CaCO3 precipitates, including travertines, tufas, and speleothems, are currently of great interest because of their potential as archives of environmental, climatic, and biologic information (e.g., Andrews et al. 1997; Bar-Matthews et al. 1997; Walter and Des Marais 1993). Detailed studies of examples of these terrestrial carbonates therefore provide valuable information to aid inte...
• 5 t ha −1 of micro-dosed manure approx. doubled the yields compared to control. Micro-dosed NPK (70 kg N ) meanwhile increased 3–4 times. Legume supplemented diet quality, and also yield season 4. Animal provides plant nutrients affects soil nutrient availability, pH buffering physical properties through its contribution organic matter pools. However, quality quantity are often low on smallho...
Abstract The water that moves upward inside the stone is affected by capillary absorption (CWA). This trend in historic and old buildings causes rapid destruction. In simple regression model, relationship between CWA with resistance (compressive strengt...
identifying active morphogenetic landforms in payam pass (northwestern iran) for geotourism planning
the proposal of geomorphologic matters in relation to tourism is one of interdisciplinary research approaches that has been considered in recent years. in this manner, geomorphological sites are defined as geomorphological landforms and processes that have acquired a scenic/aesthetic, scientific, cultural/historical and/or a social/economic value due to human perception of geological, geomorpho...
global warming is claimed to be the cause of climate change, which is often held responsible for water shortage. let geopedology represents the complex process of soil formation, out of which much can be learnt about paleoecology; soil formation being a dynamic interaction between the atmosphere, biosphere, lithosphere, and the hydrosphere. in a multidisciplinary sustainability-oriented study ...
The Dniester Canyon is a deep gorge, 100-120-140 m, between the Podil Upland on left bank and Carpathian Prut-Dniester Uplands right bank. canyon famous for its classic geological sections of Silurian Devonian systems, which there gradual transition. There are only four such incisions in world: ours, as well Czech Republic, Scotland United States. Great geomorphological attractiveness canyon: t...
uniaxial compressive strength (ucs) and elastic properties of rocks play a major and vital role for the design of any engineering structure. the specimen diameter size is one of the main factors that influencing on ucs, elasticity modulus and poisson’s ratio (e and υ). here, an attempt has been made to investigate the effect of specimen diameter size on ucs, e and υ. moreover, we studied the co...
