Figure 5.3.1 5.3. 1: Enlarged image of frosted and rounded windblown sand grains. Medium-grained rocks composed mainly of sand are called sandstone, or sometimes arenite if well sorted. Sediment grains in sandstone can having a wide variety of mineral compositions, roundness, and sorting.

Pointed crystals of white calcite and translucent yellow cubes of fluorite line the edges of this gray limestone collected near Postville in Allamakee County. Calcite (calcium carbonate, or lime) is the primary mineral in limestone, while fluorite is rare. Such crystal growths are found along open spaces (vugs or fracture traces) within the rock. Limestone: Over time, the shells and skeletons of tiny organisms like brachiopods built up on the seafloor. These shells and skeletons were made of the mineral calcite. The layers of calcite fragments pressed down on top of each other. Rondi: The weight of all those layers must have been intense. Limestone: It was.
