It is very rare. Original occurrences are magnesite deposits among serpentinites. It is named after Egon Althaus (born 1933), a mineralogist at the University of Karlsruhe, Germany.[4][2][5] References1. ^[https://www.mineralienatlas.de/lexikon/index.php/MineralData?mineral=Althausite] {{phosphate-mineral-stub}}2. ^1 Mindat 3. ^Webmineral data 4. ^Raade G. and Tysseland M. 1975: Althausite, a new mineral from Modum, Norway.
