| Drilling confirms mineralization is associated with abundant narrow quartz vein arrays, sulphides, silicification and local kaolinization. |
|
| Effective engineering characterization of granites altered through processes of kaolinization is critical for safe extraction and design of slopes for the china clay industry in south-west England. |
|
| The results of the testing confirm that the degree of alteration or kaolinization, and associated changes in mineralogy of the granite, is directly related to reduction in uniaxial compressive strength and dry density. |
|
| The china clay was formed by the alteration of feldspars in a process known as kaolinization. |
|
| Kaolinization of the feldspar has also occurred in the oxidized beds, although it primarily involved the plagioclase. |
