The results indicate that where rivers pass through the Siwalik conglomerates, the grain-size and volume of bedload is significantly modified, becoming enriched in rounded quartzite cobbles. In contrast, in rivers such as the Kosi, the bedload comprises more varied bedload lithologies and grainsizes, and more angular clasts.Question: Sample Texture (grain size, shape, sorting) SEDIMENTARY ROCKS STUDY SHEET Components Minerals/rock fragments present (approximate %) Clastic Chemical Biogenic Name Name of sedimentary rock Rock history (transporting agent, environment, etc.) coarse grain Breccia Conglomerate Sandstone Shale Limestone Click to add notes NOTES COMMENTS EStudy with Quizlet and memorize flashcards containing terms like Conglomerate, grain size, sorting, rounding, composition?, Breccia,grain size, sorting, rounding ...Classification of Clastic Sedimentary Rocks · Conglomerate, Dominated by rounded clasts, granule size and larger (>2 mm), poorly to very poorly sorted · Breccia ...Conglomerate consists of a single grain size.
