“…The Sukhaya Tunguska Formation of the Turukhansk Uplift experienced a collisional event following Mesoproterozoic deposition but prior to the Ediacaran (Nikishina, Sobornov, Prokopiev, & Frolov, ). This faulting and uplift resulted in at least 3–4 km of erosion and maximum burial temperatures of 150–200°C (Frolov et al., ). The source rocks that have been studied from the Mesoproterozoic succession are post‐mature but TOC‐rich (Frolov et al., ).…”

The source rocks that have been studied from the Mesoproterozoic succession are post‐mature but TOC‐rich (Frolov et al., ). This is in contrast to the overlying Ediacaran stratigraphy whose source rocks are immature to early mature indicating the early burial and uplift of the Sukhaya Tunguska Formation was the only significant deformational event in its history (Frolov et al., ).…”

“…The source rocks that have been studied from the Mesoproterozoic succession are post‐mature but TOC‐rich (Frolov et al., ). This is in contrast to the overlying Ediacaran stratigraphy whose source rocks are immature to early mature indicating the early burial and uplift of the Sukhaya Tunguska Formation was the only significant deformational event in its history (Frolov et al., ). The geochemical character of Sukhaya Tunguska carbonates (both dolomites and limestones) has low Mn/Sr and Fe/Sr ratios and display 87 Sr/ 86 Sr ratios, δ 13 C values, and δ 18 O values similar to other rocks of their age (Gorokhov et al., ; Pope, Bartley, Knoll, & Petrov, ), which is consistent with minimal post‐depositional alteration of the carbonates.…”

“…According to available geological data and paleogeographic (paleogeodynamic) reconstructions (Figure 5a), the north-western margin of the Siberian craton was a passive continental margin in the Mesoproterozoic-early Neoproterozoic [5,6,[34][35][36], as were its western and eastern margins [37][38][39]. The composition of Mesoproterozoic deposits, judging from coeval formations of the Siberian craton, was siliceous-carbonate, terrigenous and carbonate, and their thickness reached 2-3 km [17].…”

The geodynamic development of the north–western (Arctic) margin of the Siberian craton is comprehensively analyzed for the first time based on our database as well as on the analysis of published material, from Precambrian-Paleozoic and Mesozoic folded structures to the formation of the Mesozoic-Cenozoic Yenisei-Khatanga sedimentary basin. We identify the main stages of the region’s tectonic evolution related to collision and accretion processes, mainly subduction and rifting. It is demonstrated that the prototype of the Yenisei-Khatanga basin was a wide late Paleozoic foreland basin that extended from Southern Taimyr to the Tunguska syneclise and deepened towards Taimyr. The formation of the Yenisei-Khatanga basin, as well as of the West-Siberian basin, was due to continental rifting in the Permian-Triassic. The study describes the main oil and gas generating deposits of the basin, which are mainly Jurassic and Lower Cretaceous mudstones. It is shown that the Lower Cretaceous deposits contain 90% of known hydrocarbon reserves. These are mostly stacked reservoirs with gas, gas condensate and condensate with rims. The study also presents data on oil and gas reservoirs, plays and seals in the Triassic, Jurassic and Cretaceous complexes.

“…The East Siberian Basin was developed on the Siberian platform on an ArcheanProterozoic metamorphic basement. It has experienced multiphase tectonic movements and formed the current tectonic patterns of alternative depressions and uplifts, and Mesozoic-Cenozoic foreland basins have developed in the margin of the basin (Kheraskova et al 2009;Nikishin et al 2010;Zhu et al 2012;Du et al 2013;Frolov et al 2015). The Oman Basin is located in the southeast part of the Arabian Plate.…”

Formation and distribution characteristics of Proterozoic–Lower Paleozoic marine giant oil and gas fields worldwide

There are rich oil and gas resources in marine carbonate strata worldwide. Although most of the oil and gas reserves discovered so far are mainly distributed in Mesozoic, Cenozoic, and upper Paleozoic strata, oil and gas exploration in the Proterozoic-Lower Paleozoic (PLP) strata-the oldest marine strata-has been very limited. To more clearly understand the oil and gas formation conditions and distributions in the PLP marine carbonate strata, we analyzed and characterized the petroleum geological conditions, oil and gas reservoir types, and their distributions in thirteen giant oil and gas fields worldwide. This study reveals the main factors controlling their formation and distribution. Our analyses show that the source rocks for these giant oil and gas fields are mainly shale with a great abundance of type I-II organic matter and a high thermal evolution extent. The reservoirs are mainly gas reservoirs, and the reservoir rocks are dominated by dolomite. The reservoir types are mainly karst and reef-shoal bodies with well-developed dissolved pores and cavities, intercrystalline pores, and fractures. These reservoirs are highly heterogeneous. The burial depth of the reservoirs is highly variable and somewhat negatively correlated to the porosity. The cap rocks are mainly thick evaporites and shales, with the thickness of the cap rocks positively correlated to the oil and gas reserves. The development of high-quality evaporite cap rock is highly favorable for oil and gas preservation. We identified four hydrocarbon generation models, and that the major source rocks have undergone a long period of burial and thermal evolution and are characterized by early and long periods of hydrocarbon generation. These giant oil and gas fields have diverse types of reservoirs and are mainly distributed in paleo-uplifts, slope zones, and platform margin reef-shoal bodies. The main factors that control their formation and distribution were identified, enabling the prediction of new favorable areas for oil and gas exploration.
