This chapter presents the Late Quaternary neo-tectonic movement in the Pearl River Delta (PRD) region of China and its effects on the coastal sedimentary environment. Taking the Xilin Hill fault as the example, we have explained the reason of the PRD formation, inferred its interactions with local/regional climate and sea-level changes, and analyzed the evolution of the PRD formation and its co...

reliable characterization of subsurface soil in urban areas is a major concern in geotechnical and geological engineering projects. in this regard, this research deals with development of a 3d geological engineering model on mashhad city soil using sequential gaussian simulation (sgs) approach. the intense variability of soil in the study area has sometimes caused serious problems in civil engi...

this research was performed to determine the efficiency effect of sedimentary environment of kerman city area on soil structure bycomparing natural and reconstituted consolidation curves. in this regard, four different criteria such as sensitivity strength, stresssensitivity, schmertman criteria and the result of the uniaxial compression test were used. the base of these criteria is to compare ...

holocene in southwest khuzestan is represented by a fluvio-tidal succession termed thebahmanshir series which consists of two clayey layers separated by silty sand to silt beds. this paperdescribes the geotechnical properties of the clayey layers that have wide exposure in the lowlands of thepersian gulf coast. studied layers are generally clay sized and consist of a lesser percentage of clay m...

The coastal region of Chabahar Gulf with 1113.7km2 area has been located in the southeast of Iran. In this research, satellite images of ETM+ (2004) were used in order to zoning of sedimentary environments in this Gulf. Methodology of this research was baesd on synthesis of supervised and unsupervised classifications in GIS and ENVI softwares. Based on studies and calculat...

Methylmercury (MeHg) is the most bioavailable and toxic mercury species in the marine environment. MeHg concentration levels, methylation rates leading to MeHg formation, and methylation index (MI) are all used to assess the compliance of mercury to be methylated in the marine sedimentary environment. This paper reports on the works conducted on the MI upgrade. This paper proposes a new formula...
