Abstract

Iul'tin deposit has been widely studied using various geochemical methods. Despite of this, there is no agreed conception as to the origin of the fluids, largely due to the insufficiency of isotope data. Hence, data have been obtained on hydrogen-isotope composition. The oxygen-isotope composition of the granite and sedimentary rocks has also been examined in order to detect possible traces of interaction between meteoric waters and the country rocks in the region adjoining the deposit. The hydrogen-isotope data clearly indicate that meteoric fluids participated in the mineralization. Also, comparing the hydrogen-isotope of the fluids with the contemporary isotope for meteoric waters shows that the content of water of a different, magmatic origin in this hydrothermal system was not more than 10 percent.
