Question

Quizplus · Accepted Answer

Quartz is a very hard and durable mineral that can withstand weathering and transportation. Well-sorted and rounded grains of quartz indicate that the sediment has been transported by the energy of waves in a marine environment that have rounded and polished the grains. Therefore, the most likely environment to produce these sedimentary deposits is a beach. Rivers, glaciers, and alluvial fans typically produce sedimentary deposits with a wider range of grain sizes, shapes, and mineral compositions.
