systematics of minerals according to Dana is a system developed by James Dwight Dana for the classification of minerals according to chemical composition and crystal structure. It is used in the English-speaking world, especially in the USA . A new system was published in 1997 based on the old Dana system.
In the German-speaking area, the
Hugo Strunz system is mostly used, which is available in two editions: An old Strunz system of minerals (8th edition) and, since 2001, the new Strunz system of minerals (9th edition) , which also used by the International Mineralogical Association (IMA) and its main commission CNMNC ( Commission on New Minerals, Mineral Names and Classification ).
History of the system
The systematics of minerals was extended by Dana in 1854 in the fourth edition of his
System of Mineralogy, first published in 1837, to the chemical composition of minerals. In the course of the 20th century, the system was further supplemented against the background of scientific advances, especially in the field of crystallography . In 1941 Hugo Strunz derived his system from this. The original classification was also further developed and published in 1997 in a new system.
Structure of the system
The minerals are arranged in a hierarchical system. Each mineral has a system number, which consists of four numbers separated by dots and which should allow a clear assignment of known minerals under different names. The first number represents the mineral class. The second number stands for the type of mineral, in some cases taking into account the atomic structure. The third number stands for a group of similarly structured minerals, while the fourth clearly identifies the mineral.
