Feb 24, 2018· ┗ Most crystalline rocks contain some amount of feldspar. ┗ It is termed as one of the most common minerals (after quartz) found in the Earth's crust. ┗ It is a chief constituent of granite rocks. ┗ It forms clay minerals on undergoing the chemical weathering process.

Myrmekite - Wikipedia

As a consequence Ca gets released in plagioclase which in turn can now react upon K-feldspar to form myrmekite. Basically this process is very similar to the Ca-metasomatism on K-feldspar described above except for the Na-fluids acting as a trigger. An example is the Velay granite in the northeastern Massif Central in France.

Thus, rocks rich in feldspar commonly weather to kaolinite. In order to form, ions like Na, K, Ca, Mg, and Fe must first be leached away by the weathering or alteration process. This leaching is favored by acidic conditions (low pH). Granitic rocks, because they are rich in feldspar, are a common source for kaolinite.
