This study provides a global assessment of the abundance major oxides in deep continental crust. The combination geochemistry and seismology better constrains composition middle lower crust than either discipline can achieve alone. inaccessible nature (typically >15 km) forces reliance on analog samples modeling results to interpret its bulk composition, evolution, physical properties. A common...

– The final result of the project is to create a 2D model mine plan based on results geophysical measurements. ERT was chosen as primary method in this due fact that voids and air have very high resistivity (3,3 ∙ 1016Ωm). Voids are well recognizable results. Using Seismic Refraction Tomography (SRT) planned some profiles. SRT rarely used archaeogeophysical research.

Seismic inversion is a fundamental tool in geophysical analysis, providing window into Earth. In particular, it enables the reconstruction of large-scale subsurface Earth models for hydrocarbon exploration, mining, earthquake shallow hazard assessment, and other tasks.

• Reflection data image complex ore-bearing horizon. Mixed recording sensors and setup were instrumental for deep imaging. Interpretation benefited from well-log geological constraints. Cost-effective targeting is possible in the Bergslagen district. The Zinkgruvan mining area located on south-eastern part of district, one three major mineral producing regions Sweden. In this study, we present ...

Abstract Superimposed tectonic movement and karst erosion resulted in a combination of fractures irregular caves deep/ultradeep carbonate rocks, typically along major fault swarms. Outlining these fault-karst reservoirs mainly depends on recognizing the strong reflection seismic profiles; however, characterizing their internal structures is still difficult, which are represented as weak amplitu...
