Both natural and polished cleavage surfaces of alkali feldspar grains in a syenite from Mt.Balmaceda,the Patagonian Andes, Chile, were etched by the vapor of concentrated hydrofluoric acid solution. They were used for secondary electron and back-scattered electron image analyses with an X-ray microanalyser. Obtained electron images and distribution patterns of selected elements show that etched micropores are generally polygonal,and that they are abundant in microscopically turbid,microperthitic regions and are rare in microscopically clear,featureless regions. The data should provide more data to clarify concretely the unknown processes of plutonic perthite coarsening.
