Sandstone is made up mostly of quartz. There are two reasons for this. First quartz is one of the most abundant minerals on earth. Second is that quartz is very durable. It resists weathering and chemical change. Silica, calcite, and iron oxides are the most common cementing minerals for sand stone.
