Ny. Bragin et Ka. Krylov, Stratigraphy and formation conditions of the Jurassic siliceous and terrigenous deposits in southwestern Cyprus, STRATI GEOL, 7(4), 1999, pp. 333-342
The structure of the Jurassic deposits of the Episkopi Formation from south
western Cyprus is considered. The section is composed (from the base upward
) of (1) the Callovian-Oxfordian siliceous rocks and turbidites (30 m) with
rich radiolarian assemblages, (2) the Oxfordian mudstone (25 m) with poor
radiolarian assemblage, and (3) the Kimmeridgian-Tithonian mudstone and tur
bidite (10 m) with rich radiolarian assemblages. The radiolarian assemblage
s are correlated with synchronous faunas from the West Mediterranean region
and eastern Russia. The character of radiolarian assemblages from the Epis
kopi Formation depends on types of sediments. The registered stratigraphic
interval (Oxfordian), during which the assemblage was impoverished, coincid
es with the time of intensified terrigenous influx that was accompanied by
disappearance of coarse-grained turbidites. Thus, during the Jurassic sedim
entogenesis in Cyprus, the gradual intensification of the terrigenous non-t
urbidite sedimentation was combined with periods of growing silica accumula
tion and formation of turbidites.
