Аннотация

Геолого-петрологические, изотопно-геохимические (40Ar/39Ar анализ, данные по петрохимии и геохимии редких, редкоземельных элементов) и минералогические исследования свидетельствуют о том, что формирование раннепалеозойских базальтовых и пикритовых комплексов фундамента Западно-Сибирской плиты связано с развитием кембрийской (520-495 млн лет) субдукционной зоны Палеоазиатского океана. Использование составов клинопироксенов и амфиболов (а также программ расчетного моделирования) позволило установить РТ -параметры формирования раннепалеозойских пикритовых комплексов. Кристаллизация клинопироксенов началась на значительных (25-20 км) глубинах и при высоких (1300-1275 °C) температурах. В условиях повышенных (8-7 кбар) давлений при температурах 1540-1490 °C могло идти формирование оливина. На уровне 6.1-4.5 кбар и при значительно более низких температурах (1105-1060 °C), наиболее вероятно, образовывались амфиболы. Петрохимические исследования, а также данные по редким и редкоземельным элементам в породах рассмотренных раннепалеозойских комплексов Западной Сибири свидетельствуют о сложности их формирования при участии магматических систем с признаками базальтовых (островных дуг и задуговых бассейнов), пикритовых, шошонитовых (а также типа WPB) расплавов. В целом, учитывая сходство геохимических характеристик раннепалеозойских базальтоидов и пикритов фундамента Западной Сибири с особенностями вулканитов Камчатки, предполагается, что формирование значительной части рассмотренных древних комплексов происходило по модели, связанной (как и в случае Срединного хребта на Камчатке) с действием обогащенных магматических систем в ходе развития деструктивного окна («slab-window») при разрыве субдуцированной плиты на фоне развития обычного островодужного магматизма.

abstract = "Geological, petrological, isotope-geochemical (40Ar/39Ar analysis, petrochemical data, and geochemistry of trace elements and REE), and mineralogical researches testify that the formation of the early Paleozoic basalt and picrite complexes of the West Siberian Plate basement was related to the development of the Cambrian subduction zone of the Paleo-Asian Ocean. Using the compositions of clinopyroxenes and amphiboles (and also programs of computational modeling), we have established the Р–Т conditions of formation of early Paleozoic picrite complexes. Crystallization of clinopyroxenes began at significant depths (25–20 km) and at high temperatures (1300–1275 °C). Olivine might have formed at elevated pressures (8–7 kbar) and temperatures of 1540–1490 °C. Amphiboles formed, most likely, at 6.1–4.5 kbar and much lower temperatures, 1105–1060 °C. Petrochemical analysis and data on trace elements and REE in the rocks of the studied early Paleozoic complexes in West Siberia testify to their intricate formation involving magmatic systems with basalt (island arc and back-arc basins), picrite, and shoshonite (and also WPB type) melt characteristics. Taking into account the similar geochemical characteristics of the early Paleozoic basaltoids and picrites of the West Siberian Plate basement and the Kamchatka volcanics, we suggest that a considerable part of the studied ancient complexes formed by the model implying (as in the case of the Sredinnyi Ridge in Kamchatka) the action of enriched magmatic systems during the development of a destructive window (“slab-window”) under rupture of subducted plate on the background of common island arc magmatism.",
