Mineral Classification Sternberg Museum of Natureal
2021-11-28 Geologists first classified minerals according to their primary chemical composition, such as iron or copper. 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.

mineral Classification of minerals Britannica
1 天前 mineral mineral Classification of minerals: Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (e.g., halides, oxides, and sulfides). Several reasons justify use of this criterion as the distinguishing factor at the highest level
