On the geological interpretation of geophysical anomalies of the Tigilsky region of Western Kamchatka
Abstract
The coastal areas of Western Kamchatka north of Cape Omgon (Tigil‑Voyampolka interfluve) have for many years been the object of intensive geological and geophysical study in connection with the search for oil and gas deposits. Since the VNIGRI studies in the early 30's revealed indications of oil‑bearing potential here, geological and geophysical work has acquired a clear oil prospecting direction. To date, considerable data on the stratigraphy and tectonics of the investigated area have been accumulated, which are based mainly on the results of surface or near‑surface geologic observations. The present state of knowledge of the area is determined, first of all, by the studies of geologists of VNIGRI (B. F. Dyakov, I. B. Pleshakov, N. M. Markin) and Kamchatka RayGRU (V. G. Vasilyeva, V. P. Vdovenko, E. P. Klenova, P. A. Koval, V. V. Krylov, K. M. Sevostyanov, and others), who were engaged both in the study of regional geology and tectonics, and in the search for local brachyanticline structures. As a result of many years of research, the position of the Tigil‑Voyampolsky area in the general tectonic structure of West Kamchatka was determined, the scheme of stratigraphy of sediments composing the visible part of the geological section was developed, the prospects of stratigraphic horizons for oil‑bearing potential were evaluated, and a large number of local Paleogene uplifts were revealed. At the same time, each of these questions needs additional study, as a consensus has not yet been reached, mainly due to poorly understood deep geology and tectonics. These questions can be judged only from the data of rotary drilling on the Voyampolka structure and gravity exploration works (A. L. Voshchinsky, V. L. Goldman, Y. S. Dezhanova) in the coastal areas of the West Kamchatka plain in the Kvachina‑Voyampolka interfluve.
