metadata.value: A lithochemical and chemostratigraphic study of the boundary Upper Vendian–Lower
  Cambrian deposits of the Baltic monocline in the well sections of Leningrad Oblast and
  northeastern Estonia was carried out in the volume of the Redkino, Kotlin and Lontova
  horizons. Both common features and differences in the rock associations of individual
  horizons in different wells are revealed, which is a consequence of local variations of
  sedimentation conditions. The deposits of the Redkino horizon uncovered in the central and
  eastern parts of the region are characterized by a similar composition of rocks, represented by
  moderately deep-water sandy-clayey sediments of small thickness, formed in disoxidic and
  anoxic environments with pronounced processes of bacterial sulfate reduction. The deposits
  of the Kotlin horizon are represented by two groups of rocks. In the sections of wells in the
  east and west of Leningrad Oblast, a variety of sandy-siltstone rocks, representing coastalmarine sediments of oxidative conditions in the basin, predominate. In sections of the central
  part of the Baltic monocline (district of St. Petersburg), fine-grained deep-water disoxic
  and ferrigenous anoxic environments with a marked accumulation of siderite are common.
  Marine sandy-clay deposits of the Lontova horizon of the Lower Cambrian have similar
  lithochemical characteristics with the Kotlin deposits of the “eastern” and “western” sections
  of the territory, but they were formed under conditions of some oxygen deficiency (disoxic
  facies). Petrochemical analysis of core material showed that all the sediments studied belong
  to lithogenic sediments in which no presence of volcanic or pyrogenic material is observed.
  The formation of the sedimentary sequence of the Upper Vendian–Lower Cambrian of the
  Baltic monocline took place under the conditions of a passive continental regime with a
  gradual change of humid climatic conditions with semiarid ones.
