What minerals make up sandstone

7.1 Weathering. Sediments and sedimentary

What is the composition of a sandstone? Sandstones are composed mainly of the mineral quartz, along with different amounts of other constituents. Variations in quartz content affect a rock’s color and hardness. Rocks with greater than 90 percent quartz grains are almost white in color, and are extremely hard and brittle when struck with a hammer.Description. Conglomerate is a sedimentary rock made of rounded pebbles and sand that is usually held together (cemented) by silica, calcite or iron oxide. It is a stone similar to sandstone but the rock particles are rounded or angular gravel rather than sand. Conglomerate is a coarse-grained rock that is often formed in riverbeds.
