| 1. | Dickite has perfect cleavage in the ( 001 ) direction.
|
| 2. | Dickite and other kaolin minerals are commonly developed by weathering of feldspars and muscovite.
|
| 3. | It was found that there are six layers within the kaolin layer within dickite.
|
| 4. | It can occur intermixed with dickite, kaolinite, montmorillonite and other clay minerals.
|
| 5. | Dickite occurs with other clays and requires x-ray diffraction for its positive identification.
|
| 6. | Dickite has a monoclinic crystal system and its crystal class is domatic ( m ).
|
| 7. | Within dickite there exists dominant O-H bonding, a type of strong ionic bonding.
|
| 8. | Dickite sometimes contains impurities such as titanium, iron, magnesium, calcium, sodium and potassium.
|
| 9. | Dickite is an important alteration indicator in hydrothermal systems as well as occurring in soils and shales.
