The Genesis of Oil in connection with a 1-layer Model of the Earth’s Crust

For the formation of oil (PG), a certain geological and geochemical environment of the Earth's Crust is necessary. Geologically, the current PG models are based on a 2-layer model of the Earth's Crust, consisting of Granite and Basalt layers. However, as the drilling of the Kola Superdeep Borehole (SG3) showed, there is no basalt layer on the continents. A model of a 1-layer Earth's Crust was compiled, consisting of a granite layer on the continents and a basalt layer in the Oceans:[1 layer  Мodel of the Earth's Crust Galant (MECG), ( AAPG, Athens 2007; EGU, Vienna 2013,2022;)] сonsist of separated layers of  Granite  and separated layers of  Basalt. This Model of the Earth's Crust Galant (MECG) fundamentally changes the geological and geochemical setting of the Earth's Crust and hence the PG processes. Basalts and Granites are antipodes and therefore fluids migrating from the mantle with the goal of generating oil passing through the Earth's Crust that does not have Basalts but has only Granites will behave differently - respectively. In connection with the change in the geological and geochemical situation, the parameters of the fluid migrating from the mantle will also change: the C-O-H ratio, reactions with the components of the layer, the supply and removal of components, the change in T, the intensity of degassing, the change in the fugacity of O, the depth of the depleted mantle, etc. Since the Kola on the Baltic Shield did not reveal the basalt layer and due to this, the depth [According based on 1 layer Model of the Earth's Crust Galant (MECG), ( AAPG Athens 2007, EGU Vienna 2013)] of the granite layer reaches the mantle deeply and the greater the thickness the thickness of the depleted mantle is greater, from this it can be assumed that the mantle gave up light hydrocarbon components concentrated in the upper horizons of the Lithosphere, and heavy hydrocarbon components still remained in the depleted mantle or are now slowly migrating upward into the granite layer. This may explain that granites contain more light hydrocarbons. Due to the change in the physical and chemical conditions of the Earth's Crust, the PG depth zone changes, expands or localizes, and the composition of the oil changes accordingly. CONCLUSIONS: In connection with the 1-layer model of the Earth's Crust, the energy-material exchange between the domains of the Earth, the Mantle and the Lithosphere changes. Characteristics of the parameters of physic-chemical conditions change. And also the tactics, strategy, philosophy of PG research should change, taking into account the new model of the Earth's Crust.
