        <p>Исследованы тектоно-магматические факторы локализации литий-фтористых гранитов Востока России. В основу исследования положены представления дальневосточных геологов о глубинных структурах внутриплитной активизации. Использована модель очаговой структуры с мантийными источниками тепла и рудогенерирующими магматическими комплексами. Проведен специальный металлогенический анализ Востока России в приложении к редкометалльно-оловоносной формации субщелочных лейкогранитов, в том числе литий-фтористых гранитов. Главным фактором тектоно-магматического развития Востока России, локализации рудогенерирующих гранитов и формирования редкометалльно-оловорудных районов являются очаговые структуры. На глубоких ярусах очаговых структур располагаются области разуплотнения мантии и земной коры, источники тепла, магм, флюидов и гранитоидные криптобатолиты. Вблизи современной поверхности сосредоточены относительно крупные массивы лейкогранитов, малые интрузии оловоносных монцонитоидов и литий-фтористых гранитов. Очаговые структуры соответствуют рангу рудного района. Приведены примеры очаговых структур на юге региона: Баджальская, Мяо-Чанская, Иппато-Мерекская, Хогду-Льянчлинская, Арминская и др.; на севере: Певекская, Куйвивеем-Пыркакайская, Куэквунь-Экиатапская, Иультинская, Телекайская, Центрально-Полоусная, Омсукчанская и др. Выделены три типа рудных районов по степени эрозионного среза очаговых структур и литий-фтористых гранитов. Намечены закономерности эволюции очаговых структур и место в геологической истории рудоносных гранитов. Предложена классификация очаговых структур и ее сопоставление с классификациями региональных интрузивных и металлогенических подразделений. Установлено, что, несмотря на многообразие тектонических и геолого-петрологических обстановок Востока России, интрузии литий-фтористых гранитов подчиняются единым тектоническим и магматическим факторам. Выделены и классифицированы тектоно-магматические факторы локализации литий-фтористых гранитов Востока России: геофизический, орогенный, геоблоковый, магматический, метасоматический и дизъюнктивный.</p>

        <p>We have investigated tectonic and magmatic factors of Li-F granites localization of the East of Russia. The study is based on the ideas of Far Eastern geologists about the deep structures of intraplate activity. A model of a source structure with mantle heat sources and ore-forming magmatic complexes was used. We carried out a special metallogenic analysis of the East of Russia as applied to the rare metal-tin-bearing formation of subalkaline leucogranites, including Li-F ones. Source structures are the main factor in the tectonic and magmatic development of the East of Russia, localization of ore-forming granites and the formation of rare-metal-tin ore regions. On deep layers of source structures there are areas of the mantle and earth's crust decompaction, heat, magmas and fluids sources, as well as granitoid cryptobatholiths. Relatively large massifs of leucogranites, small intrusions of tin monzonitoids and Li-F granites are concentrated near the modern surface. The source structures correspond to the rank of the ore region. The source structures in the South of the region are: Badzhalskaya, Miao-Chanskaya, Ippato-Merekskaya, Hogdu-Lianchlinskaya, Arminskaya, etc.; in the North: Pevekskaya, Kuiviveem-Pyrkakayskaya, Kuekvun-Ekiatapskaya, Iultinskaya, Telekayskaya, Central Polousnaya, Omsukchanskaya, etc. Three types of ore regions have been identified according to the degree of source structures and Li-F granites erosion. We have also outlined the patterns of source structures evolution and their place in the geological history of ore-bearing granites. A classification of source structures and its comparison with the classifications of regional intrusives and metallogenic subdivisions are proposed. It has been established that, despite the diversity of tectonic, geological and petrological settings in the East of Russia, the intrusions of Li-F granites are regulated by the same tectonic and magmatic factors. The tectonic and magmatic factors of Li-F granites localization in the East of Russia are identified and classified as geophysical, orogenic, geoblock, magmatic, metasomatic and disjunctive.</p>
