Siliceous rocks as important raw materials are used in various fields of national economy. Such siliceous rocks as diatomite and tripolite are widespread at the territory of the Republic of
Moldova. There was carried out prospecting of diatomite and tripolite during several years in order to detect occurrences of siliceous raw material in the Dniester and Prut rivers basin. There were also examined geological peculiarities, composition and properties of the rocks. Main results are presented in this article. As a result, for the first time there were highlighted perspective areas, recommended for further detailed studies: Stanca Murovaya, Oxentia, Lalova, Ocniţa, Ohrincea, Maramonovca and Chetrosu. As well there were specified three varieties of diatomite rocks on the basis of SiO2 contence: „pure” diatomite (SiO2 > 70%), diatomaceous marl (SiO2 – 50-70%),
diatomaceous clays (SiO2 < 50%). There were studied chemical, mineralogical composition an specific structures for the mentioned rocks. |
