Soil larger soil particles, and their mineralogy is often inherited from the parent material of the soil, but may include products of weathering (such as concretions of calcium carbonate or iron oxide), or residues of plant and animal life (such as silica phytoliths). Quartz is the most common mineral in the sand or silt fraction as it is resistant to chemical weathering, except under hot climate; other common minerals are feldspars, micas and ferromagnesian minerals such as pyroxenes, amphiboles and olivines, which are dissolved or transformed in clay under the combined influence of physico-chemical and biological processes. Due to its high
Emery, Utah identify archaeological sites as Fremont, is not very different from that made by other Southwestern groups, nor are its vessel forms and designs distinct. What distinguishes Fremont pottery from other ceramic types is the material from which it is constructed. Variations in temper, the granular rock or sand added to wet clay to insure even drying and to prevent cracking, have been used to identify five major Fremont ceramic types. They include Snake Valley gray in the southwestern part of the Fremont region, Sevier gray in the central area, Great Salt Lake gray in the northwestern area, and Uinta and
