The group of submerged plants are characterized by high ash content; and they accumulate large amounts of Ti, Mn, Cu, Zn, Zr, Pb. There are statistically signi ficant differences between the plants in ecological groups of reservoirs and rivers in terms of Mn, Cu, Pb contents in the tissues (elements with a 100 % frequency). According to the spatial analysis the reservoirs of the northern geochemical province account for 71 % of the Mn anomalies and 80 % of the Cu anomalies, including the Braslav region – 46 % of the Mn anomalies and 59 % of Cu. Mn, Cu, Pb maximum concentrations are characteristics of submerged macrophytes such lakes as Snudy, Losvido, Maloye Beloye, Beloye (Luninets District), Beloe (Surmino), Svityaz. Among submerged macrophytes within lakes the abnormal accumulation of Mn has been noted for Charophyta (61 % of cases), Myriophyllum and Ceratophyllum, Cu – Charophyta, Isoetes and Lobelia dortmanna, Pb – Isoetes, Charophyta and Potamogeton. The macrophytes within rivers are characterized by the higher ash content and the average content of Mn, Cu and Pb in comparison with the lakes plants. Areas with identified Cu and Pb anomalies in the submerged plants are confined to the central geochemical province of Belarus (the Svisloch river accounts for 67 % of anomalous values of Cu and 33 % of Pb). Anomalous values of Cu have been fixed in the tissues of the Ceratophyllum and Potamogeton, Pb – mostly in Potamogeton. The cluster analysis has distinguished a group of plant species as a part of the following genera: Potamogeton, Myriophyllum, Elodea, Ceratophyllum and Sparganium. The group is characterized by elevated contents of Ti, V, Cr, Mn, Ni, Cu, Zn, Zr, Pb and recommended as indicators of polluting water objects with heavy metals.","PeriodicalId":52778,"journal":{"name":"Zhurnal Belorusskogo gosudarstvennogo universiteta Geografiia geologiia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47526230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study of structural and textural features and composition of potash deposits has been given attention since the time of discover of the Starobin deposit. Systematic study of salt rock petrology has been started after the discovery of the Starobin deposit. Until now in the petrology, there is no recognized rational genetic classification of the structures of salt rocks being potash (potassium-magnesium) ore. The name of certain structure is based on the secondary features that are brightly expressed, color or similarity with different objects. The aim of the present work is an element recognition of the primary sedimentary features of rocks, systematization of primary and secondary characteristics and their typification according to petrochemical parameters.

The historical stages of formation, advantages and disadvantages of the current system of the ATD of the Republic of Belarus are revealed. The positive and negative international experience of conducting of administrative and territorial transformations is systematized. The significant disproportions in the resource, demographic and economic potential of the regions of Belarus and their various contributions to the social and economic development of the state are determined. Based on the centro-peripheral principle, a scheme of the regions of Belarus by the level of socio-economic development has been developed, which indicates significant changes in the development of regional economic complexes that have occurred over the past decades. About 20 % administrative districts are characterized by the properties of the center or semi-center, which have the ability to perform the functions of regional centers in the new ATD. More than 30 % administrative areas are peripheral in terms of socio-economic development.
