The grain-size distribution of surface sediments in the Bohai Sea (BS) and the northern Yellow Sea (NYS), and its relationship with sediment supply and hydrodynamic environment were investigated based on grain-size compositions of surface sediments and modern sedimentation rates. The results showed t...
Development of a grain-size determination method based on digital images of muddy sediments in coastal areas The grain-size distribution is a fundamental parameter for assessment of coastal environments. In coastal areas, grain-size analysis of sediments is hamper... A Umehara,H Takashima,Y Yoshimor...
The methods discussed include comparison techniques employing standard charts or the Shepherd fracture grain size standards; measurement techniques based on determination of the number of grains per unit area (Jeffries method), the number of triple points per unit area, or the number of grains ...
Variation in the effective strength of the lithosphere allows for active plate tectonics and is permitted by different deformation mechanisms operating in the crust and upper mantle. The dominant mechanisms are debated, but geodynamic models often employ
Samples were sectioned from these bars for grain size determination and etched in a solution that consisted of (50% H2O, 25% HNO3, 15% HCl, 10% HF) for 10s. Download: Download high-res image (203KB) Download: Download full-size image Fig. 2. Geometry of the standard tensile test ...
