  • Defining Minerals | Earth Science | Visionlearning

    The importance of crystal structure. The graphite-diamond mineral pair is an extreme example of the importance of crystal structure. These two very different minerals have exactly the same chemical formula (C), but the crystal structure of the two minerals is very different. In graphite, carbon atoms are bonded together along a flat plane, as shown in Figure 3.

    Similarly, insertion of layers of water molecules between the T-O-T sheets of pyrophyllite produces the structure of smectite clays. The vermiculite and smectite groups are therefore expanding type sheet silicates and as the water is incorporated into the structure the mineral increases its volume.

  • What Causes Color in Minerals?

    Allochromatic - minerals whose coloring agents are not part of the ideal chemical composition. IDIOCHROMATIC MINERALS Some minerals always have the same color, because of the presence of certain elements in the mineral's normal molecular structure. Examples: Gold is yellow because the element Au absorbs all other colors except yellow.

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 ...

    This is the basic structure of micas (biotite, muscovite), and also of clay minerals. Finally, when all four oxygens are linked to other tetrahedra, either by oxygen sharing or via an inserted metal ion, we get three-dimensional framework structures. This is the structural style of the mineral quartz, and of the feldspar family of minerals.

    The structure of minerals is often seen in the shape of crystals. The law of constancy of interfacial angles--- Angles between the same faces on crystals of the same substance are equal. This is a reflection of ordered crystal structure (See figure 5.5 in the textbook). Crystal structure can be determined by the use of X-rays.
