alteration scar samples containing gypsum, alunite, and jarosite were collected from the following sites: Pit scar, Hottentot scar, Hanson scar, Straight Creek South and East, Bitter Creek scar, and Capulin scar.
Alunite has been found in NSW Australia, Taiwan, Hungary, Tuscany, Italy where it is currently mined, and in a number of locations in the USA. The natural alum stone can be used as a natural deodorant and it is sold for this purpose.
It is a combination of both Stichtite and Serpentine, which are both strong healing stones and can be used for kundalini work, and it works well combined with them for this purpose. This green stone can be used to help you to stimulate kundalini awakening.. and will help to move the kundalini energies from the base of the spine, up the body to the crown chakra.

alunite supports the general trends found in the Xray diffraction data for the behaviour of the aaxis with Al/Fe content. The dehydration of the Al3+ ion could be a significant contribution to the activation energy barrier to alunite formation as found for other minerals. Finally, dynamic light
Alunite characteristics can provide a good indication of gold ore potential in a high sulfidation epithermal system. Alunite is a potassium sulfate mineral that forms in hydrothermal systems. Sulfates such as alunite and jarosite are common in hydrothermal environments and have distinctive NIR spectra.
Mineral Alunite is known to crystallize in the trigonal division or hexagonal crystal system, which can be seen clearly visible when the mineral is viewed with the aid of petrographic polarizing light microscopes.
Alunite Mineral Deodorant by Cocos consists of potassium alum, a naturally occurring mineral. Unlike aluminium compounds that can be found in mass market antiperspirants, potassium alum is completely safe for human health. It prevents body odour by inhibiting the growth of odourcausing bacteria, but it doesn't affect perspiration.

Jun 14, 2019· Alunite is a hydrous aluminum sulfate, KAl 3 (SO 4) 2 (OH) 6, from which alum is manufactured. Alunite is also called alumite. It has a Mohs hardness of to 4 and coloring in white to fleshred. Usually, it's found in the massive habit rather than as crystalline veins.
Overall, alunite rates suggest that Alrich sulfates are likely to survive longer than jarosite on Mars and will buffer the system to higher pH, while jarosite dissolves more quickly and buffers the system to a lower pH. Therefore, alunite can survive longer in more basic conditions than jarosite. References:

Jun 04, 2014· Alunite is a sulfate mineral first discovered in Monti della Tolfa, Rome in the 15 th century. It is rarely found in the massive material cavities as distinct crystals. It occurs as veins and replacement masses in rhyolite, trachyte and other potassium rich volcanic rocks.
Jarosites and alunites are members of the alunite supergroup of minerals and can be described by the ideal formula AB3(SO4)2(OH)6, with Bsites being occupied by Fe 3 and Al3. Although numerous cations can occupy the Asite, potassium and sodium are incontestably the most commonly encountered in natural solids of this group as well as in syn
Azurite is a soft stone, named for its deep "azure blue" color. It is a copper carbonate mineral found in the upper oxidized portions of copper ore formed in masses, nodules, tabular or prismatic crystals, sometimes with a vitreous luster.
