A break in the acetabulumâthe socket located on each side of the pelvisâis less common than other types of pelvic or hip fractures. It usually occurs as the result of a car accident or fall from a significant height, with damage to other bones and soft structures in and around the hip and pelvis.
What are some characteristics of all minerals? Color is one of the most important distinguishing characteristics of minerals. Minerals vary widely in color: some are translucent and appear as white or light gray, even pastel, while others are darker and reflect light. Streak refers to the color that a mineral takes on when ground into a powder. Along with hardness, it is an important characteristic.
Olivine always has silicon and oxygen as well as iron or magnesium or both, (Mg, Fe)2SiO4. The physical properties of minerals include: How physical properties are used to identify minerals is described in the lesson on Mineral Formation. Mineralogists divide minerals into groups based on chemical composition. mineral is formed through natural processes and has a definite chemical composition. Minerals can be identified by their characteristic physical properties such as crystalline structure, hardness, density, flammability, and color. Minerals are crystalline solids.
