Aus BiodynWiki
- Through physical weathering of mica. In the process, among other things, primary clay minerals form, and through further chemical breakdown, transformations into secondary clay minerals.
- Through chemical weathering of base-rich magmatic rocks and metamorphic rocks, series of secondary clay minerals arise, up to the complete disintegration of crystal lattices, with formation of the aforementioned amorphous, colloidal hydroxides.
- New formation of secondary clay minerals through the synthesis of the colloidal mass of silicon and aluminium hydroxides.
