Abstract According to the results of geological fieldworks in the north-east of Sakhalin Island on the Schmidt Peninsula and in the Pogranichny Depression, Cenozoic outcrops were studied in order to explore the siliceous deposits of the Pilskaya formation. Samples were taken for analytical studies, small structural forms that are indicators of tectonic stress, were studied. It is shown that the fracture intensity depends on the lithology, the position of the observation point relative to disjunctive and/or plicative structures. A sharp nonuniformity of the stress field in the vicinity of the Pogranichny Depression is noted, reflected in the nature of the bedding planes, structural discontinuities and parageneses.
