Experimental model of weathering of felspars. Application to staining. I. Orthoclase



Experimental model of weathering of felspars. Application to staining. I. Orthoclase



Anales de Edafologia y Agrobiologia 41(1/2): 165-175



Orthoclase was incubated for 15 days in aqueous solution at pH values ranging from 3 to 11, and at 30 or 60 degrees C. The mineral was then removed from solution and stained with haematin and cobaltinitrite to indicate the extent of weathering. The degree of staining was affected little by the incubation temperature, but was intensified by increasing acidity of the solution.
