This contribution proposes the lithostratigraphy of the Tertiary volcanosedimentary complex of the České středohoří Mts. The superficial volcanic products of the České středohoří Mts. Are divided into theree formations. The Ústí Fm. (36.1-25.5 Ma) includes basanites and their concomitant volcaniclastics including fossiliferous sediments, and represents products of early rift development - the filling of a rift valley. The Děčín Fm. (30.8-24.7 Ma) is composed of trachybasalts and trachybasaltic resediment tuffs, which are erosional relics of a composite volcano - the product of more advanced stage of rift evolution. The Dpbrná Fm. (24.0-19.3? Ma), represented by basanitic laves, was produced as a result of a possible remobilization of the magma chamber. All these formations represent ono volcanic cycle (uppermost Eocene - lowermost Miocene, with a maximum in the Oligocene). The basanitic intrusions penetrating the Most Fm. Sediments are comprised in the fourth lithostratigraphic unit, the Štrbice Fm. (13.4-9.0? Ma). It is most probably a product of a younger volcanic cycle (Middle Miocene) and extends to the Most Basin, too. The Ústí Fm is largely correlated with the Střezov Fm. Of the Most Basin.
