Bulletin of the Mineral Research and Exploration

Noises in marine seismic data are one of the biggest obstacles in seismic imaging. The most significant step in seismic data processing is the removal of seismic noise, which can be classified as instrument and background noise. Noise attenuation usually results in improved seismic interpretation by increasing the signal-to-noise ratio. In this study, we will focus on attenuating these seismic noises with several data processing techniques. A number of denoising examples describing swell, strumming/tugging, and cavitation, which are background-type noises, and streamer-mounted device noise (Nautilus), which is an instrument-type noise, were illustrated by analysing a marine 3D seismic dataset recorded …

A Brief Overview On Geothermal Scaling, Tuğba Isik, Alper Baba, Dornadula Chandrasekharam, Mustafa Muammer Demi̇r

Bulletin of the Mineral Research and Exploration

Hot spring waters are rich in terms of minerals. Since there are dramatic changes in thermodynamic parameters in geothermal power plants, such as a decrease in temperature and pressure, severe precipitation occurs throughout the system components in an uncontrolled manner. There are three main chemistries in deposits: carbonates (mainly calcium carbonates), silicates (metal silicates), and sulphides (antimony sulphide-stibnite). Energy harvesting is remarkably reduced out of the insulating nature of the deposit. Various actions need to be taken to mitigate this undesirable issue of scaling in geothermal systems. Geothermal systems are in fact quite complex, and the composition of brine and, …

Bulletin of the Mineral Research and Exploration

The Monitoring of the Ganos Fault data presents significant opportunities and challenges for earthquake detection, location and magnitude calculations, source mechanism solutions, and discovery of fault zone waves. This study indicates mostly of preliminary data analysis and seismological evaluations. While narrow distance aperture installation has an opportunity to detect microearthquakes, it also causes significant difficulties in determining the source parameters of micro-earthquakes. Extracting microearthquakes from continuous data shows that special strategies need to be used. MONGAN data revealed the presence of many earthquakes with magnitude M<1.0 in the study region. These earthquakes are mostly out of network earthquakes and it is very difficult to obtain reliable solutions due to the insufficient azimuthal distribution of the stations. It is obvious that different network techniques and wave particle motion analyzes are contributed to the location and source parameters. Although the fault zone structure consists of two different lithologies that make significant differences in seismic wave phase arrival times and wave amplitudes, we observe fault zone head waves on both sides along the Ganos fault. Moment tensor analyzes depict that reliable source mechanism solutions can be obtained using a small number of station records.

The main objective of this study is destined to combine the Analytical Hierarchy Process (AHP), Weight of Evidence (WOE), Logistic Regression (LR) methods and geographic information system (GIS) to predict landslide susceptibility of the Echorfa region (northwestern of Algeria). Nine factors such as slope, aspect, lithology, distance to faults, lineaments density, distance to the streams, precipitations, land use and altitude are included in landslide susceptibility evaluation process. A detailed landslide inventory map was established by satellite images and filed surveys. Three landslide susceptibility maps are established using the different statistical models. Five landslide susceptibility categories are generated by the GSI …
