This paper aims to study the geochemical characteristics of shale of Disang group of Eocene age. Geochemical study and the data reported indicate that Shales are deposited under the marine condition. Tectonic setting was active continental margin to passive continental margin and sediments were derived from volcanic and/or granitic source area. Study reveals that Source-rating of studied shale ...

Mount Kubing holds significant potential as a tourist attraction, despite being situated in tectonic zone prone to faults. Its size and attractions make it suitable for both travel exploration. Hence, the study has been conducted identify subsurface structures that can structural fault lines when mitigation occurred during an earthquake or landslide. The derivative analysis method is used deter...

S U M M A R Y A 2-D upper crustal structural profile with seven steeply dipping faults was constructed from the Los Angeles Region Seismic Experiment phase II (LARSE II) seismic refraction data recorded over the north central Transverse ranges and adjacent Mojave desert in southern California. The profile extends to a depth of approximately 4 km. The faults were identified from distinctive feat...

Abstract Granitic rock is considered one of the most important economic materials used as building materials, ornamental stones, and other purposes. According to previous radiological studies conducted on these granites, it was found that activity concentrations 238 U, 232 Th 40 K granitic rocks are natural well radiation effects not harmful due radioactivity examined granites so can be exploit...
