Mica Genesis in Hawaiian Soils1
- T. C. Juang and
- G. Uehara2
A soil mica having a formula Na0.11 NH40.06 K1–24 (Al, Si) (Al, Fe, Mg) O20 (OH)4 has been identified in soils of the wet uplands in the Hawaiian Islands. It contains 7.2% potash and is predominantly a mixer-layered mica with vermiculite-montmorillonite and chlorite. The mica is concentrated in the surface horizons, and its concentration increases with soils formed under increasing rainfall and elevation. Biological recycling of potash is proposed as a mechanism for its formation.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
