SIZE: 14pt" lang=EN-US>Calcareous clastics in the tropical beaches are important fractions, which differ from the silicic constituents in the physical character. The beach sediments are chosen to study on the influence of calcareous clastics on the particle grain size distribution through different pre-treatment procedures. After dissolving the calcareous clastics by hydrochloric acid, the main part of particle size distribution curve will be more peaky and move to the fine end. Because of great variability in the shape and species of calcareous clastics in the beach sands, knowing of the species and content of calcareous clastics is necessary to understand the grain-size parameters and study the dynamic environment of beaches similar to those around Tongguling.
