Introduction of Quartz Group Minerals
Quartz group minerals are a group of oxide minerals composed of quartz and mineral species with the same or closely related chemical composition. A total of 12 minerals. Except for quartz, each silicon ion in their crystal structure is surrounded by 4 oxygen ions, forming a silicon-oxygen tetrahedron, the centers of the 4 oxygen ions are located on top of the four corners of the tetrahedron; and each The silicon-oxygen tetrahedrons each share a corner vertex (that is, the oxygen ions on the public corner vertex) with the adjacent four tetrahedrons, so as to be connected to each other into a three-dimensional frame-like structure.
