4,714 Minerals arranged by the New Dana classification system.
The classification of minerals was based on chemical composition by Dana in the fourth edition (1854, in two volumes) of his book System of Mineralogy. [5] [6] For the 20th century, this classification was completed thanks to scientific progress, particularly in the field of crystallography.
Dana’s System systematically arranged the 352 mineral species known at the time first by their chemistry (elements, halides, sulfides, silicates, etc.), and then by their atomic structure or symmetry of the atomic arrangement. He published his list in 1837 in A System of Mineralogy.
Dana Classification 8th edition - NATIVE ELEMENTS AND ALLOYS. Click on a subgroup to view further divisions. 1.1. Metals, other than the Platinum Group. 1.2. Platinum Group Metals and Alloys. 1.3. Semi-metals and non-metals.
The number 14 represents the new Dana class for anhydrous carbonates. The second number 01 represents the new Dana type for simple cation formula. The third number 01 represents the calcite group with its hexagonal-rhombohedral structural similarities.
The document discusses general classifications of minerals based on three criteria: 1) Their abundance in rocks - essential minerals are the main components while accessory minerals are present in small amounts.
In the mid-19th century, American geologist, mineralogist, and zoologist James Dwight Dana created a classification system that arranged minerals first by their chemistry and second by their atomic structure or symmetry of the atomic arrangement. This system is called Dana’s System of Mineralogy.
