Natural Science Forum / Earth Science / Mineralogy / January 2006About kalunite
Hello, I am looking for information and pictures related to kalunite. So far, I have only found little information about it by Googling (mostly under the article about alum from the Columbia Encyclopedia). I do have huge chunks of alum crystals at home though those technically are not kalunite (which is the mineral form of the compound occuring in nature). What rocks contain kalunite? Rocks that have kalunite in enough abundance to the point that it is visible would be great. Any clue is welcome (like the title of a good mineralogy book with information on it). Hello S.A., I could not find "kalunite" in either Dana's or Fleischer's references. "KALINITE" is cited in Dana's System of Mineralogy as a Potash Alum. Alunite has (OH) in its chemistry and is converted to Alum, which has (H2O) in its composition. Mendozite is Soda Alum that may be of interest in your search. Hope this helps, Will E. > Hello, > [quoted text clipped - 7 lines] > clue is welcome (like the title of a good mineralogy book with > information on it). Thanks for the extra clue, will1. I googled kalinite and found many more references about it, all confirming that kalinite is indeed potash alum. I found a clue about the difference between kalinite and kalunite somewhere else, however. In Powerword 2005 (a well-known Chinese/English electronic reference collection), kalinite is the fiber form of potash alum, whereas kalunite is the rock form of the same mineral. Ah! Try "K-ALUNITE". It's all in the dash.
