V. DenisovaInstitute of geology of Komi Science Centre of RAS, SyktyvkarThe crystals of zircon can reveal information about their formation environment due to their resistance to external influence and also inclusions observed of them. Zircon can contain different mineral inclusions: biotite, plagioclase, quartz, àpatite, etc. However no information about gold inclusions has been available in the zircons from granites of the Sudpolar Urals. The study results of the inclusions of gold in accessory zircon of the Kozhim granitic massif are presented in this paper. The studied mineral is a dark-brown translucent short-prismatic crystal containing an inclusion of gold and nodules of quartz. According to our studies, the inclusion of gold formed during the growth of zircon and it is gold covered with a thin film of oxide gold. It was confirmed that the crystallization of the studied zircon occurred at a temperature of 800 °с and above at the stage of formation of granites of Kozhim massif. We suggested the presence of an additional temperature mode when the temperature decreased to 700 °C and below during the postmagmatic stage.

This allows applying different methodologies to determine a more accurate temperature mode of formation of the given rocks. The study results of accessory granitoids zircon of the Subpolar Urals (the Badjaju, Yarot, Kozhim and Nikolaihsor massifs) are presented in this paper. The temperatures of crystallization of the mineral using thermometry of zircon saturation and the classic evolutionary -morphological analysis were determined. The comparison of data, obtained in different ways, was carriedout. The temperatures of formation of the studied massifs of the Subpolar Urals were specified.
The results of the study of accessory apatite from the Kozhym massif rocks have been presented in this paper. Apatites of the same morphological type were found in granites. The Kozhym massif granites formation temperatures by apatite were determined by the Watson and Bea saturation thermometry. These temperatures were compared with the previously obtained ones for accessory zircon of the same massif.
