Riphean Kresttsy和Pavlov Posad沉积盆地在东欧地台（EEP）中占据不同的位置。揭示了这些盆地沉积杂岩的陆源-矿物组合（TMA）的组成特征及其与盆地内和外部碎屑物质来源的关系。在EEP中部的里菲沉积盆地的发展过程中，建立了两个阶段（前裂陷槽和裂陷槽）。前裂陷槽层序遗迹仅记录在巴甫洛夫波萨德盆地沉积序列的底部。这两个盆地形成于走滑应力作用下的裂陷槽阶段。巴甫洛夫波萨德盆地的Aulacogen序列形成于一个阶段，而在两个阶段的Kresttsy盆地的序列积累。
The Riphean Kresttsy and Pavlov Posad sedimentary basins, which occupy different positions in the East European Platform (EEP) are considered. Compositional features of terrigenous–mineral associations (TMA) of sedimentary complexes in these basins and their relation to the intrabasin and external sources of the detrital material are revealed. Two (preaulacogen and aulacogen) stages in the development of Riphean sedimentary basins in the central EEP are established. Relics of preaulacogen sequences are recorded only at the base of the sedimentary succession in the Pavlov Posad basin. These two basins formed at the aulacogen stage under an influence of strike-slip stresses. Aulacogen sequences of the Pavlov Posad basin formed in one stage, whereas sequences of the Kresttsy basin accumulated during two stages.
