  Solved A soil profile consists of 10-m-thick fine sand of

  Step 1. A soil profile consists of 10-m-thick fine sand of effective 1 size 0.15 mm above a very thick layer of clay. Ground-water level is at 3 m below the ground surface. Determine the height of capillary rise, assuming that the equivalent capillary tube diameter is 10% of the effective size and the sand surface is similar to smooth glass.

  Dynamic responses of sand-clay mixtures under long-term …

  202431 · In this study, the dynamic responses of sand-clay mixtures under a large number of shear cycles were investigated through 25 constant-volume cyclic direct simple shear tests on sand-clay mixtures with sand contents of 0 %, 25 %, 50 %, and 75 %. The results indicate that high sand contents and high cyclic stress ratios accelerate the …

  In-situ analysis and genetic investigation of Li-bearing …

  202431 · Clay-type Li deposits are poised to play a pivotal role in addressing the surging global demand for Li. The McDermitt clay-type Li deposit, located in Nevada, is the largest Li deposit in the United States, with Li hosted by a clay-rich sequence of smectite-dominated intervals and illite-dominated intervals, respectively. However, the occurrence …

  Lithium isotopic constraints on the evolution of continental clay ...

  2024329 · Lithium isotopes represent a promising tool to explore the extent of continental clay contribution to marine siliciclastic sediments, as clay minerals preferentially incorporate the lighter Li isotope ( 6 Li) relative to upper crustal materials ( 44 – 47 ).

  3.2 Effective Porosity – Hydrogeologic Properties of Earth …

  Effective porosity ( ne) is defined as the ratio of the volume of interconnected pore spaces ( VI) to the total volume ( VT) as defined in Equation 6 and illustrated in Figure 7. Interconnected void space allows groundwater to move into and out of porous material.
