REPARTIŢIA ELEMENTELOR DIN GRUPA TR ÎN STRATELE DE VÂRSTĂ VENDIANĂ DIN REGIUNEA CENTRALĂ A BAZINULUI r. NISTRU

Abstract

In the lithologic formations of the northern part of Republic Moldova considerably big concentrations of the TRGroup elements have been discovered such as La, Ce, Yb, Yand Sc. These elements and their chemical components areapplied in a variety of different fields: chemistry, optics, metallurgy, cosmonautics and aeronautics, electronics, atomic energy, etc. The geological premises for the TR Group elements presence in the Nistru River area are considerably highand, taking into consideration their exclusive importance for the modern technologies, some Geological and Geochemical prospecting’s can be projected aiming to solve the problem for localization of some TR significant accumulationwithin the terrigenous stratums.
