The practice of process mapping of acid metasomatites consisting of quartz and muscovite in the structures of Eastern Hizovaara (Republic of Karelia) is considered. These muscovite ores were formed under the conditions of polychronic metamorphism and metasomatism and are confined to the metasomatic zonality. The so-called metasomatic columns are used to visualize the metasomatic zonality. These are combinations of simultaneously formed zones of different mineral composition, represented by thin bodies within the ore lenses of the deposit. The highest muscovite occurrence is observed in the metasomatites developed along biotite gneisses. Various principles may be used, depending on the goals and objectives of the process mapping of metasomatic rocks. In estimation mapping at the scale of 1 : 10000 to 1 : 50000, the major amounts of data on the ore body are obtained when studying the formation type and the petrographic and petrochemical composition of metasomatites. In the process of identification of industrial types and grades of ores, the specific metasomatic and chemical zonality features of respective rocks must always be taken into account. Application of the facies analysis methods for this purpose enables identification of metasomatic bodies and zones that combine the facies of certain thermobarometric conditions and are characterized by a set of mineral parageneses. This approach is most practical for the selection of industrial types and grades of ores and may be used for all types of metasomatic changes of rocks.
