Opal: The Play-of-Color Gem – Formation and Symbolism
Formation of Opal 1. Geological Process. Opals are formed from a solution of silica and water. When water runs through the Earth's crust, it picks up silica from sandstone and carries it into cracks and voids. Over time, as the water evaporates, the silica deposits build up, eventually forming opal. This process can take millions of years, and the conditions must be just right for ...

Metamorphic Ore Minerals
Metamorphic ore minerals are minerals that form during the process of metamorphism, which is the alteration of pre-existing rocks due to changes in temperature, pressure, and/or fluid composition. Metamorphic ore minerals can form in a wide range of rock types, including sedimentary, igneous, and other metamorphic rocks. Some examples of …

Sandstone | Composition, Properties, Formation, Uses
Sandstone Formation. Formation of the sandstones are cemented grains that may either be fragments of a pre-existing rock or be mono-minerallic crystals. The cements binding these grains together are typically calcite, clays, and silica. Grain sizes in sands are defined (in geology) within the range of 0.0625 mm to 2 mm (0.0025–0.08 inches).
