Использование метода диффузионной хронометрии позволило определить время поступления свежих порций магмы в приповерхностный очаг вулкана Безымянный для шести извержений в 2006–2012 гг. и сопоставить их с зафиксированными эпизодами активности вулкана. Выделено два типа извержений вулкана Безымянный, контрастная кайма ортопироксена в которых начинает формироваться в периоды: а) до 3 лет до начала извержения и б) до 2 месяцев до начала извержения. Показано, что эти различия обусловлены двумя различными механизмами подпитки приповерхностного очага вулкана Безымянный.</p></abstract><trans-abstract xml:lang="en"><p>Zoned crystals record changes in magma evolution, such as injection of mafic magma into a shallow magma chamber, which often triggered to eruption of arc volcanoes. We applied diffusion chronometry for reverse zoned crystals of orthopyroxene from 6 eruptions of Bezymianny volcano during 2006–2012 years and showed correlation between time of injection of new magma and recorded seismicity. We descripted two type of Bezymianny volcano eruptions, which driven by different trigger mechanisms: 1) orthopyroxene rims formed during up to 3 years previous to eruption; 2) orthopyroxene rims formed during 0–2 months previous to eruption.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>смешение магм</kwd><kwd>зональность минералов</kwd><kwd>пироксены</kwd><kwd>диффузия</kwd><kwd>диффузионная хронометрия</kwd><kwd>вулкан Безымянный</kwd></kwd-group><kwd-group xml:lang="en"><kwd>magma mixing</kwd><kwd>crystal zoning</kwd><kwd>diffusion</kwd><kwd>pyroxene</kwd><kwd>diffusion chronometry</kwd><kwd>Bezymianny volcano</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Давыдова В.О., Щербаков В.Д., Плечов П.Ю., Перепелов А.Б.
