Detecting Edges Of Geologic Sources From Gravity Or Magnetic Anomalies Through A Novel Algorithm Based On Hyperbolic Tangent Function, Hanbing Ai, Yunus Levent Eki̇nci̇, Ahmad Alvandi, Hazel Deni̇z Toktay, Çağlayan Balkaya, Arka Roy

Turkish Journal of Earth Sciences

Directional derivative-based edge detectors are commonly used to outline the abrupt lateral variations in densities or magnetizations of geologic sources from potential-field datasets. Some subtle traces of faults, lithological contacts, and lineaments can be made more visible on anomaly maps using these algorithms. However, these algorithms generally suffer from common limitations such as blurry edges with low-resolution or faulty boundaries. To minimize these challenges, we proposed a new efficient edge detector that benefits from the hyperbolic tangent function. The performance of this detector was tested on the responses of a synthetic gravity model and Bishop's complex magnetic model. A Gaussian …

Turkish Journal of Earth Sciences

In 1989, the first prolific hydrocarbon reservoirs were discovered by Saudi Aramco in the highly porous and permeable friable continental sandstones (Unayzah reservoirs) and shallow marine carbonates (Khuff reservoirs) of the Paleozoic successions in south of Riyadh, Central Arabia. These successions were strongly affected by tectonic movements (Caledonian and Hercynian orogenesis) and Early and Late Paleozoic Gondwana glaciations. Therefore, some sections were fully eroded or significantly reduced in their thickness. The sequence stratigraphic interpretation of the Paleozoic successions helped to understand the depositional environments and regional distribution of the source, reservoir and cap rock facies in an improved palynologic studies. …

Top To Bottom Interactive Velocity Analysis Using Travel-Time Ellipses And First Break Times From Walkaway Vertical Seismic Profiling Data: A Synthetic Study, Cemal Erdemi̇r

Turkish Journal of Earth Sciences

An interactive velocity analysis method is introduced in this paper and its efficacy is tested on various walkaway vertical seismic profile (WVSP) modeled data sets. In WVSP surveys, interval velocity profiles are determined fairly accurately along the VSP borehole using first break travel time picks from the zero-offset VSP (ZVSP) data. However the accuracy of these vertical velocities fade away quickly as the source distance (offset) from the VSP borehole increases due to possible horizontal changes in the geology or dips of the horizons. If the layer boundaries are not known, a simple approach type of ray tracing using horizontally …

Turkish Journal of Botany

Gamma-aminobutyric acid (GABA) is currently considered to be an important stress metabolite with regulatory functions in plants. Exogenous GABA is known to be able to enhance the tolerance of different plant species to drought and salt stress. However, its effects on the functioning of stress-protective systems in triticale, an intergeneric wheat-rye hybrid with specific adaptation strategies to abiotic stresses, remained completely unstudied. We studied the effects of exogenous GABA (0.5 mM) on the growth as well as on the antioxidant and osmoprotective systems of triticale seedlings (cv. 'Rarytet') under simulated drought (15% PEG 6000), salt stress (100 mM NaCl), or …
