Dimension stone converted to dimension stone production. However, first the stone shattered by heavy and indiscriminate blasting must be removed. Dimension stone is separated by more precise and delicate techniques, such as diamond wire saws, diamond belt saws, burners (jet-piercers), or light and selective blasting with Primacord, a weak explosive. A variety of igneous, metamorphic, and sedimentary rocks are used as structural and decorative dimension stone. These rock types are more commonly known as granite, limestone, marble, travertine, quartz-based stone (sandstone, quartzite) and slate. Other varieties of dimension stone that are normally considered to be special minor types include alabaster (massive gypsum),
Anamosa Limestone Anamosa Limestone Anamosa Limestone or Anamosa Member is a dolomitic limestone quarried out of Stone City, Iowa, which is located along the Wapsipinicon River about two miles west of Anamosa, Iowa. It is distinguished by its uniform texture, color, and banding, its durability and most of all by its distinct planar and undulating varve–like laminations. This distinctive stone forms part of the Gower Formation, the youngest Silurian strata in Iowa. The Gower is overlain unconformably by a mid–Devonian formation. The color classification is Buff, which is described as a warm shade of light to moderate gold. Anamosa Limestone has been
