Basin structures and sediment accumulation in the Baikal Rift Zone: Implications for Cenozoic intracontinental processes in the Central Asian Orogenic Belt

摘要: Abstract In this paper we present a review of sedimentological, geomorphological, lithological, geochronological and geophysical data from major, minor satellite basins the Baikal Rift Zone (BRZ) discuss various aspects its evolution. Previously, most detailed sedimentological have been obtained central BRZ, e.g., Baikal, Tunka Barguzin, used by many scientists worldwide. We add new information about peripheral part make an attempt to provide more comprehensive view on BRZ sedimentation stages environments their relations local regional tectonic events. A huge body was years ago Soviet geologists therefore is hardly accessible for international reader. pay tribute efforts extent as format journal permits. structural facial features sedimentary sequences better understanding environments. addition, tectono-sedimentation stages, neotectonic volcanism region. Finally, consider key questions evolution point view, in particular, correlation Mesozoic Cenozoic basins, bilateral growth rift, Miocene environment events at Miocene/Pliocene boundary, Pliocene Pleistocene deformations rates. The deep boreholes surface occurrences pre-Quaternary sediments, distribution Hovsgol lakes sediments showed that 1) do not fit extensional structures inherited them; 2) stage characterized low topography weak processes; 3) rifting mode shifted slow fast ca. 7–5 Ma; 4) late high rates reflect subsidence basin bottoms.
