The aim of CCM is to collect, document and to help improve existing or proposed classifications of minerals. The CCM intends to maintain informed all the members of IMA about the new developments on the classification of minerals, and to promote meetings for their discussion.
The various classifications of minerals. It is well known that the classification of minerals has changed throughout the ages the criterion of classification following the development of the mineralogical science.
The criterion was first based on practical purposes, then on physical properties, later on chemical properties.
Mineral classification today is largely structural, when the relation and hierarchy between minerals are based on structure similarity. The ancient classification of minerals was mainly based on their practical uses, minerals being classified as gemstones, pigments, ores, etc.
In the middle ages Geber Jabir Ibn Hayyaan, - proposed a classification of minerals based on the external characters and on some physical properties such as fusibility, maleability and fracture. This physical classification was developed by Avicenna Ibn Sina, , Agricola and A. Werner , published by his student, L.
Emmerling This system was substantially refined by F. Dana since With Werner the physical classification attained its maturity, and was generally adopted at the end of the XVIII century. However, it became far too complicated. For instance, Werner mentioned 54 varieties for colour.
Cronstedt seems to be the first to have outlined a classification whereby the chemical properties were taken first, followed by the physical properties. With the development of chemistry the chemical properties became more and more important, and J.
Berzelius in proposed a chemical classification of minerals. He recognized that minerals with the same non-metal anion or anionic group had similar chemical properties and resembled one another far more than minerals with a common metal.
At this time Christian Samuel Weiss introduced the seven crystal systems and Mitscherlich discovered isomorphy and polymorphy Dana, the founder of Dana System of Mineralogy, strongly contributed to the development of the chemical approach , , 3-rd and 4-th editions.
With this knowledge, Gustav Rose combined chemistry, isomorphy and morphology to produce a chemical-morphological mineral system: I - Elements, II - Sulfides, III - Halides, and IV - Oxygen compounds, divided into simple and complex oxides, as carbonates, phosphates, silicates, borates, sulfates. The highest standard of this classification was achieved in the System of Mineralogy by E. Groth , that made this classification widely accepted.
After , when the first structures of minerals were determined, the structural criterium for classification was taken into account. The first classifications of this type, which take in consideration the distribution of bonds in a structure, are that of silicates proposed by Machatschki , Naray-Szabo and developed by Bragg Winterkorn Engineering Applications of Soil Mineralogy doi Pertinent also are engineering specialty uses of relatively pure clays such as bentonite.
The importance of the stability and durability of engineering facilities containing soil mineral constituents places emphasis on chemical mineralogy, i. However, physical - mainly optical - identification methods play an ever increasing role in detecting potentially troublesome minerals.
In practically all engineering uses of soil minerals, their actual and potential interaction with the water substance is of special significance.
While this interaction varies in degree and type as a function of the extent, molecular composition and structure of the accessible surfaces, there exists a unifying element of great theoretical and practical promise in the fact that practically all soil minerals as well as the water substance are volumetrically essentially oxygen ion structures. Some of the major consequences of this are pointed out in the paper.
Several reasons can be advanced for previous lack of use of mineralogy as a taxonomic criterion--lack of mineralogical data, emphasis on broad environmental features as differentiating criteria, and uncertainty as to correlations between clay mineral species present in soils and soil properties.
Mineralogy is directly introduced into soil classification at the family level in the USDA System and also is employed together with other features to differentiate certain taxa at other categorical levels. This is a reflection of remarkable advancements in knowledge and techniques in soil mineralogy, as well as a desire to base soil classification on properties of the soil itself.
Some problems still remain--lack of complete mineralogical data for representative soils, need for more convenient and precise methods of allophane and halloysite determination because of their pronounced effects of soil properties, and need for better correlations of montmorillonite and other and clays with soil properties. The discovery of the crystalline nature of a large portion of the clay fraction of most soils gave emphasis to crystal chemistry with its implications concerning bonding and sources and position of charge.Emmerling Stage The microscope stage is flat and can be rotated.
The greater the difference between a mineral's RI and that of the enclosing cement, the rougher the surface of the mineral appears. Limonite and goethite are important as a source of low-grade iron and nickel ore. Groth , that made this classification widely accepted. In the middle ages Geber Jabir Ibn Hayyaan, - proposed a classification of minerals based on the external characters and on some physical properties such as fusibility, maleability and fracture.
It is formed from clay sediments in contact with the magma, and is located in skarns and hornfels Table 6. Unlike calcite, Mg calcite, aragonite and dolomite are not formed by biochemical processes or by direct precipitation from seawater, but they are generally secondary mineral formed by process of dolomitization.
