Алтайский ордовикский бассейн, располагавшийся в Чарышско-Инской и Ануйско-Чуйской СФЗ, был морской акваторией, обособленной как от Уйменско-Лебедского, так и от Салаирского одновозрастного бассейна. Зафиксированные в алтайских и салаирских разрезах следы глобальных седиментационных и (или) биотических событий могут служить прецизионной основой для прямой корреляции местных стратиграфических подразделений с ярусными подразделениями Международной стратиграфической шкалы.</p></abstract><trans-abstract xml:lang="en"><p>Study of the Ordovician sedimentary sequences of Gorny Altai and Salair has revealed lithological and paleontological features correlating with global sedimentary events:</p><p>(1) The Acerocare Regressive Event (an initial event in the Early Tremadocian);</p><p>(2) Black Mountain Transgressive Event (Early Tremadocian);</p><p>(3) Peltocare Regressive Event (Tremadocian);</p><p>(4) Kelly Creek Regressive Event (Late Tremadocian);</p><p>(5) Ceratopyge Regressive Event (Late Tremadocian);</p><p>(6) Billingen Transgressive Event (Early Floian);</p><p>(7) Stein Lowstand Event (Middle Darriwilian);</p><p>(8) Vollen Lowstand Event (Sandbian);</p><p>(9) Arestad Drowning Event (Middle Sandbian);</p><p>(10) Frognerkilen Lowstand Event (Early Katian);</p><p>(11) Linearis Drowning Events 1 and 2 (Middle Katian);</p><p>(12) Terminal Husbergoya Lowstand Event (Hirnantian); and</p><p>(13) Hirnantian Lowstand Event (HICE) (Late Ordovician).</p><p>The chronostratigraphic levels with traces of the global sedimentary events in the Uymen-Lebed structural-facies zone (SFZ) (Gorny Altai) differ from those in the Charysh-Inya and Anui-Chuya SFZ (Altai). In the Ordovician, the Altai basin located in the Charysh-Inya and Anui-Chuya SFZ was a marine area separated from both the Uymen-Lebed basin and the coeval Salair basin. The traces of the global sedimentary and/or biotic events in the Altai and Salair sections can be used as a precise basis for direct correlation of the local stratigraphic units with the units of the International Stratigraphic Chart.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>событийная стратиграфия</kwd><kwd>седиментационное событие</kwd><kwd>ордовик</kwd><kwd>Горный Алтай</kwd><kwd>Салаир</kwd></kwd-group><kwd-group xml:lang="en"><kwd>event stratigraphy</kwd><kwd>sedimentary event</kwd><kwd>Ordovician</kwd><kwd>Gorny Altai</kwd><kwd>Salair</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">Aceñolaza F.G.
