Lowsphericity

Lowsphericity is a term used in the field of geology and mineralogy to describe the shape of a mineral or rock crystal. It refers to the degree to which a crystal deviates from a perfect spherical shape. In contrast to high sphericity, which describes crystals that are nearly spherical, low sphericity indicates that the crystal has a more irregular or elongated shape. This characteristic can be influenced by various factors, including the crystal's growth conditions, the presence of impurities, and the specific crystal structure of the mineral. Lowsphericity is often observed in minerals that grow in environments with limited space or where growth is constrained by surrounding crystals. The term is particularly relevant in the study of sedimentary rocks, where the shape of detrital grains can provide insights into the transport and depositional history of the sediment. Additionally, low sphericity can affect the physical properties of a mineral, such as its density and surface area, which in turn can influence its behavior in geological processes.
