“…Радость оттого, что ее посчитали за человека, и тревогу от необходи-мости бежать, не узнав продолжения 13 . В силу этого возникает своего рода парадокс, преодолеть который Ларичевой-графоманке пока не под силу: она стремится обрести голос, но не доверяя себе до конца в мире мужских авторитетов (муж, Радиолов, Упхолов, Батогов), стремится к тради-ционной нарративности, завершенным сюжетам, завершить которые все-таки не может.…”

С. Ю. Воробьева. Речевая репрезентация гендерного сознания в современной «женской» прозеВ статье представлены типологические признаки «феминного письма», обнаруженные в текстах современных авторов-жен-щин, формулируются методологические принципы выявления гендерной составляющей на уровне речевой организации про-изведения. Ключевые слова: гендер, гендерная поэтика, гендерный би-лингвизм, дискурс, феминизм, феминистская критика, феминное письмо. speech Representation of the Gender Consciousness in the Modern 'female' Prose s. Yu. VorobyevaThe article presents typological features of 'feminine writing' identified in the texts of modern women writers; methodological principles are set up for the identification of the gender element on the level of the work speech organization.

The phase relationships and distributions of rare earth elements, Sc, Y and Li between aluminofluoride and aluminosilicate melts in the model granite system Si-Al-Na-K-Li-F-O-H at 700 °C, 1 and 2 kbar with a water content from 3 to 50 wt. %. were experimentally studied. Based on the obtained and available experimental data on phase relationships in a granite system saturated with water, fluorine and containing rare elements, a comparison was made with the parageneses of rare-metal cryolite-containing granites from three deposits in Eastern Siberia are Zashikhinsky, Katuginsky and Ulug-Tanzeksky. It has been shown that the processes of liquid immiscibility between granite and salt aluminofluoride melts, which manifest themselves at high contents of fluorine and lithium in the system, contribute to the accumulation of rare elements in salt cryolite-like melts. At a temperature of 700 °C and a pressure of 1 and 2 kbar, crystallization of the aluminofluoride melt occurs in the granite system, from which cryolite is formed. It is in association with cryolite and lithium micas that the considered natural objects contain minerals of rare and rare earth elements containing fluorine, such as pyrochlore, gagarinite, etc. As a result of a comparison of experimental and natural data, the hypothesis about the important role of liquid immiscibility in the formation of cryolite is confirmed. It is assumed that cryolite can serve as a reference mineral for rare metal-rare earth mineralization in granites with high lithium and fluorine content.

The effective solubilities (maximum contents) of Ta and Nb in acidic magmatic lithium-fluoride melts of varying alkalinity and alumina content were experimentally determined at the dissolution of Ta–Nb and Nb minerals: pyrochlore, microlite, ilmenorutile and ferrotapiolyte at T = 650–850 °C and P = 100 and 400 MPa, and also the partitioning of Ta and Nb in mineral–melt systems was studied. When pyrochlore is dissolved in granitoid melts at P = 100 MPa and T = 650–850 °C, the highest effective solubilities of Nb (0.7–1.8 wt. %) are obtained in alkaline melt; they decrease significantly (up to 0.03–0.5 wt. %) in subaluminous and peraluminous melts. Increasing the temperature increases the solubility (content) of Nb in the melt. When dissolving microlite, similar dependences of Ta solubility were obtained. In peraluminous granitoid melt microlite remains stable, while pyrochlore becomes unstable. It has been established that in alkaline and subaluminous melts, a decrease in pressure from 400 to 100 MPa does not have a significant effect on the dissolution of microlite and pyrochlore, while in the peraluminous melt the Ta and Nb contents noticeably decrease. The dependences of the solubility of Nb and partitioning of Nb between granitoid melts and ilmenorutile on the alkalinity–alumina content of the melt are similar to those for the dissolution of columbite and tantalite. The dependences obtained by dissolving ferrotapiolyte, pyrochlore and microlite differ from them.
