This is the main problem that covers general geological conditions. Therefore, the purpose of this research is to map surface geology in general as an effort to present geological information, while the aim is to find out the geomorphological, stratigraphic, geological structure, and hydrological aspects. The research method begins with a literature review, survey, and interpretation of field data. Environmental observations provide information about the landscape including the terrain morphology unit. Trellis-patterned, rectangular river, old mature river, and periodic/permanent river. The constituent rocks are alluvial, and the Kasai Formation. Geological structure in the form of anticline and syncline. The hydrology consists of surface water and groundwater. Research in Menapo Ujung Tanjung II has succeeded in finding the structure of bricks, which are thought to function as waterways. This assumption cannot be justified scientifically.

Lahat is one of the districts within the province of South Sumatra, the site of research, saving many cultural remains, one of them from the paleolithic period, which for so long received no attention from environmental researchers. This is the basis of the main problems that cover geology in general. Therefore, the purpose of this study is to conduct surface geology mapping in general as an effort to present geological information, while the aim is to know the geomorphological aspects, stratigraphy, geological structures associated with existence in paleolithic sites of research area. The research method begins with literature review, survey, analysis, and interpretation of field data. Environmental observations provide information about the landscape consisting of terrestrial morphology units, weak corrugated morphology units, and strong corrugated morphology units. The rivers are in the Old River, the Adult River, and Periodic /Permanent River. The constituent rocks are Gumai Formation, Benakat Air Formation, Muara Enim Formation, Kasai Formation, and alluvial. The geological structure is a strike slip fault that flows northeast-southeast. The study was conducted on the Kikim River, Lingsing River, and Pangi River, which stretches from east to west with direction from south to north.

<p class="Normal1"><em><span>The research aimed to reconstruct the geological structure and tectonics based on fault, shear fracture and veins data of the Botutonuo and surrounding areas. This research was conducted with DEM interpretation method to determine the lineament pattern of rock offsets and the geological structure mapping method. Geological structure analysis was carried out by using kinematic analysis method of fault, fracture and veins data using the Win Tensor program to obtain the direction and type of stress forming it. Based on the results of the analysis, extensive stress and transtensive stress trendingN-S resulted direction of Normal Fault and Slip Fault (NE-SW). Extensional stress trending (NE-SW) is the result of reorientation stress trending (N-S) in the North Sulawesi arm which is accommodated by the Gorontalo Fault regime. Normal fault and slip fault are the 2nd order faults of the 1st order faults of Gorontalo faults.</span></em></p>

The analysis of geological and geophysical materials in order to study the peculiarities of the geological structure of the Vikulov Formation within the Vodorazdel license area was carried out. The presented factual material makes it possible to characterize the geological structure of the investigated area more informatively and for interpreting of seismic materials. The analysis of geological information (GIS and test results) confirms the approved water–oil contact (WOC) level in the investigated section of the deposit, which makes it possible to recalculate its reserves.

AbstractIn deep tunnels with hydro-geological conditions, it is paramount to investigate the geological structure of the region before excavating a tunnel; otherwise, unanticipated accidents may cause serious damage and delay the project. The purpose of this study is to investigate the geological properties ahead of a tunnel face using electrical resistivity tomography (ERT) and tunnel seismic prediction (TSP) methods. During construction of the Nosoud Tunnel located in western Iran, ERT and TSP 303 methods were employed to predict geological conditions ahead of the tunnel face. In this article, the results of applying these methods are discussed. In this case, we have compared the results of the ERT method with those of the TSP 303 method. This work utilizes seismic methods and electrical tomography as two geophysical techniques are able to detect rock properties ahead of a tunnel face. This study shows that although the results of these two methods are in good agreement with each other, the results of TSP 303 are more accurate and higher quality. Also, we believe that using another geophysical method, in addition to TSP 303, could be helpful in making decisions in support of excavation, especially in complicated geological conditions.

AbstractTransient electromagnetic method (TEM) is often used in urban underground space exploration and field geological resource detection. Inversion is the most important step in data interpretation. Because of the volume effect of the TEM, the inversion results are usually multi-solvable. To reduce the multi-solvability of inversion, the constrained inversion of TEM has been studied using the least squares method. The inversion trials were performed using two three-layer theoretical geological models and one four-layer theoretical geological model. The results show that one-dimensional least squares constrained inversion is faster and more effective than unconstrained inversion. The induced electromotive force attenuation curves of the inversion model indicate that the same attenuation curve may be used for different geological conditions. Therefore, constrained inversion using known geological information can more accurately reflect the underground geological information.

Heiyu Lake zone of Daqing is located in the southwest hollow borderland of Heiyu Lake and on the arching transitional zone of Daqing placanticline. Based on the geological background of Heiyu Lake, this paper analyzes the landform, the regional geological structure, the formation lithology and the irruptive rock and other metallogenic conditions in detail. The indispensable geological conditions for forming geothermal field in layers were summed up. Combining with the development characteristics and geophysical data of formation, the bore hole site of geothermal well and target stratum were ascertained. The four major elements of forming geothermal resources in this region were confirmed by carrying out geothermal drilling.
