 The results of complex study of the Oxfordian deposits in Ukrainian Precarpathian are presented. According to today stratigraphic scheme, the Oxfordian deposits in the territory of Carpathian Foredeep are represented by reefogenic complex, in which Boniv, Rudky and Gorodok suites were allocated. Only Boniv suite stratotype was described by author (V.G. Dulub, 1995). In the results of our investigations the sratotypes of Rudky and Gorodok suites are determined and consistently described, and the extended stratotype of Boniv suite is specified. Section opened by the well Pidluby-105 in interval 922,5–1002,8 м is proposed as a stratotype of the Rudky suite. The stratotype of Boniv suite was opened by the well South Kochanivka-1 and by author was determined in interval 2770–2952 м. According by new data the suite is determined in interval 2720–2952 м. For the Gorodok suite is proposed the folding stratotype, which is composed of the sections opened by wells (from below to up): Dashava-405 (2180–2150 м), Rava-Ruska-2 (1189–1165 м), South Grynivka-2 (3330–3298 м), Didushychy-1 (2627–2597 м), Rudky-120 (1600–1570 м), Verchany-1 (1988–1960 м). Lithological and paleontological characteristic of these sections are given.
