Based on the data of the State Cadaster of Territories and Objects of the Natural Reserve Fund of Ukraine, the peculiarities of the distribution of geosites over the territories of administrative-territorial units have been analyzed and categories, types, significance and the degree of value have been established. The ways of reconciliation of classifications of geological sites with the legislative and regulatory base pertinent to the nature reserve fund of Ukraine have been proposed. The procedure for legislative establishing of geosites has been analyzed and ways of cooperation with the regional departments of the Ministry of Environment for their promotion and protection have been proposed. With the establishment, the object of the nature reserve fund at the legislative level receives the category - “natural monument”, the type of origin - “geological”. Depending on the significance (national or local) and value (international, national, regional, local) of the geological monument of nature, a regime for its protection is established. Based on these characteristics, the object is entered into the State Cadastre of Territories and Nature Reserve Fund Objects. In order to harmonize the existing classifications of different authors with legislative and regulatory acts on the Nature Reserve Fund of Ukraine, the following is proposed. According to the geomorphological features of the subtype of geosites, it is proposed to adopt the unified name of the morphosculpture indicated in the State Cadastre and establish five subtypes: rock outlier; exposure; underground cavity; water body; others. The class is distinguished based on physicomechanical properties of the soils of the natural monument, on which the intensity of destruction and, accordingly, the direction of the conservation measures depend on: easily wetted; readily soluble; medium strength; durable. According to engineering-geological processes that took part in the formation (exposure) of the monument, the following subclasses are proposed: denudation; erosiondenudation; erosive; abrasion, karst-suffosion; technogenic, etc. It is advisable to further separate the geological monuments according to the subject of research: mineralogical, petrographic, lithological, stratigraphic, paleontological, etc., which is proposed by other authors.
