Common member of the alunite supergroup. The Al analogue of jarosite and the K analogue of natroalunite. Alunite has been used for dating (K-Ar method) of weathering processes in ore deposits or of the deposition of alunite in caves.
Beneficial for full health in plants and animals. Sources. As might be expected of the third most common element in the Earth’s crust, aluminum is present in a great number of minerals, and is relatively rich in clay, alunite and mica minerals.
PDF | Chemical bulk analyses of previously XRD determined intermediate alunite–natroalunite minerals indicate anomalous high contents of REE, Sr, Ba, Ca and P. The alunite in the collected samples occurs as veinlets or nodules cross–cutting different hydrothermal clay deposits,...
Clays and clay minerals are nature's most common nano-material. The study of both natural and synthetic nano-composites made up of clays and organics offers great promise for the discovery of new materials for use in medical, pharmaceutical, and material industries.
