Grain size characterization of siliciclastic sedimentary and sedimentary rocks Sediment sorting and mineralogy can also be used to name siliciclastic sedimentary rocks, particularly sandstones. If a sandstone contains little silt and clay (e.g., less than 15% by volume), it is said to be an arenite.
A: Chemical dissolution is when a solute contacts a solvent and forms a solution by dissolving. Dissolution is the reverse of the precipitation process, and the two processes form a dynamic equilibrium. The precipitation of a solid form or the evolution of gas occurs when evaporation or another process removes the solvent from the solution.
