Minerals are defined as: naturally-occurring, inorganic, solid materials, with a crystalline structure, and a well-defined chemical composition that can be written as a chemical formula. Geologists give proper names to different minerals.
Define: What is a mineral: A solid with a highly ordered atomic arrangement and a definite (but not necessarily fixed) homogenous chemical composition. Highly ordered atomic arrangement: internal structural framework of atoms/ions arranged in a regular repeating geometric pattern. -> crystalline (compared to amorphous) .
29 Ιαν 2023 · In geology, a mineral is a naturally occurring solid that has a well-defined chemical composition and crystal structure. Most minerals are inorganic, although some mineralogists allow for minerals that are organic compounds or else made by organisms rather than geological processes.
Minerals may be identified by different physical and chemical properties. It is important to understand that a minerals is usually identified by a variety of properties. No single property is diagnostic for all minerals. Common diagnostic properties include: •Color •Streak •Luster •Hardness
Minerals. Naturally Occurring - minerals must be formed naturally - glass, concrete, synthetic diamonds, rubies and emeralds don’t count. Inorganic - minerals are not formed by anything that was ever alive. Therefore, materials such as: Ivory, Amber, Coal, Pearls are not minerals! Crystalline.
