Transbaikalia is considered to be a montage of three superterranes: Baikal-Vitim, Aldan-
Stanovik and Mongol-Okhotsk. These superterranes consist of a number of smaller terranes and
are presented by ophiolites, back-arc, island arc, flysch-olistrostromovy formations. Bichektui
Geological Reserve composed of Riphean, Devonian, Keuperterranes, where marine deposits
with unconformity are overlapped by continental Jurassic-Cretaceous sediments, belongs to
Mongol-Okhotsk superterrane. Ripheanterrane is presented by phyllites, metasandstones, schists
and is limited by tectonic zones. Analogs of the given terrane are found in the region in the form
of blocks of the Onon suite. Devonian terrane is composed of sandstones and siltstones with
rare problematic trace fossil and crinoids. Analogs of Devonian terrane were not found in the
region. Keuperterrane consists of sandstones, siltstones with lenses of limestones and myarianmonotis
remains. Its analogs are often found in isolated blocks of Transbaikalia, the Far East and
Verkhoyane. Terranes of Jurassic psephites and tuffaceous-sedimentary deposits of Unda-Daya
series are limited by thrusts and faults and are presented in the sections of intermountain areas of
Transbaikalia and Mongolia. Continental deposits of turginskaya and kutinskaya suites with local
unconformities overlap these formations and make isolated intermountain areas of the region.
