Abstract

The article is focused on the most recent investigations of glaciotectonic structures in high escarpment exposures of the Vistula valley from Dobrzyń to Kuzki in the western part of the Płock Basin. Deformations involve Neogene and occasionally the Lower Pleistocene deposits and they are not expressed as landforms. Structural investigations and analysis of archival geological data provided new information on the origin of large-scale shear structures. Results obtained are clearly contrary to the concept of Brykczyński (1982) regarding valley-side glaciotectonics in the Płock Basin. An emergence of the extensive zone of serial thrust structures of significant amplitude (up to 100–150 m) was found to have not been controlled by a palaeovalley. A driving mechanism is interpreted as a gravity spreading in front of ice sheets advancing from north-northeast during the South Polish Complex (Dorst-Elsterian).

Abstract

A ccording to the Polish Geological and Mining Law the granting of a concession for the exploration of a hydrocarbon deposit and the production of hydrocarbons from a deposit, or a concession for the production of hydrocarbons from a deposit in Poland is proceeded according to a tender procedure or open door procedure (upon a request of an entity). O n June 28, 2018 the Polish Minister of the Environment announced 5 tender areas. These areas (promising for discoveries of conventional and unconventional oil and gas deposits) were selected by the geologists of the Polish Geological Institute-NRI and Department of Geology and Geological Concessions of the Ministry of the Environment based on the geological data resources stored in the National Geological Archive. These are: Bestwina-Czechowice, Królówka, Pyrzyce, Złoczew i Żabowo. The main exploration target on the areas located in central and north-western Poland (Pyrzyce, Żabowo and Złoczew) is related to Permian Rotliegend sandstones and carbonates of the Zechstein/Main Dolomite. The Bestwina-Czechowice and Królówka areas (southern Poland) are prospective for conventional and hybrid-type accumulations of gas in the Miocene of the Carpathian Foredeep below the Carpathian Overthrust and in the Paleozoic-Mesozoic basement. The beginning of the 4th bidding round for hydrocarbon concessions is planned in Q4 2019. The entity can also choose the area and apply for a license submitting an application to the Ministry of the Environment. The area indicated by the entity cannot be the subject of a tender or any other concession, and the maximum acreage is 1,200 km2.
