The main difference between the different types of sand is in their composition. Siltstone, quartzite and limestone sand are composed of minerals that make up sandstone. These minerals include quartz, feldspar, mica and calcite. Siltsands have a higher percentage of quartz than other sands, while limestone sand has more calcite. Quartzite sand has a higher concentration of feldspar than siltstone or limestone sand. All these types of sand can be found in nature, but they may also be manufactured for use in construction projects.
