GEOCHEMISTRY OF RARE-EARTH ELEMENTS IN TORGASHINO SUITE LIMESTONES AND FLUIDOLITES, ARGILLISITES AND CALCITE ONYXES CONTAINED IN THEM (EASTERN SAYANS)

The Purpose of the paper is to study the features of rare-earth element (REE) geochemistry in limestones and post-sedimentation products including fluidolites, argillisites and calcite onyxes of the carbonate stratum of the Torgashino limestone deposit. Methods. The mass-spectrometry method with inductively coupled plasma is used for studying the REE behavior. The tests have been carried out in the multiple-access center “Analytical Center for Natural Systems Geochemistry” of the Tomsk State University. Results. The features of REE geochemistry are considered in the Torgashino suite limestones and fluidolites, argillisites and calcite onyxes contained in them. The distribution spectra of REE, Eu (Eu/Eu*), Ce (Ce/Ce*), light REE / heavy REE and other have been studied. Conclusions. Argillisites penetrating carbonate strata are characterized by the input of all REE while limestones and low-temperature hydrothermal formations in the form of calcite onyx have been formed in the presence of removal of both lanthanides and heavy REE. The analysis of REE distribution allows to make a conclusion on the different nature of argillisites which are the product of the fluidization explosive process and Torgashino suite limestones, which these processes were imposed on.
