The article is devoted to the approach to geothermal zonality. The results of geothermal studies of oil and gas bearing deposits in the northern territory of Novosibirsk region and adjacent areas are presented. Geothermal zoning was carried out, and the major geothermal anomalies were determined. The features of the geothermal zonality of Mesozoic sediments in the region under investigation are first of all defined by the material composition of the Paleozoic basement, the structural arrangement, and the warming effect of ground water during its crossflows from deeper lying horizons. Formation temperatures get leveled within the boundaries of Aptian-Albian-Cenomanian sediments, and no anomalies are distinguished. The highest geothermal gradients sup to 3,6-4,6 °C/100 m and correspond to the edge zones of the development of intrusive formations of pre-Jurassic rocks. Lower gradients sup to 2,4-3,0 °C/100 m and characterize the regions, in which Paleozoic carbonate rocks occur.

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.

Recently, in the Republic has been deploying drilling explorations from the eastern part to less studied central and western areas. In this reason, had a particular importance the generalization of the available geological and geophysical materials related to the new focus territory, the evaluation of the prospects of individual lithologic-stratigraphic complexes and the forecasting of deep-seated oil and gas reservoirs. Studies carried out in this direction are given in this paper, which describes the analysis of different petrophysical data. At the same time were re-interpreted reservoir and petrophysical properties of rocks, mesocenozoic deposits taken from the drilled exploratory wells and geological material of the areas of oil and gas bearing area, where are widely distributed deposits of the productive strata (PT-lower Pliocene). As a result of analysis and interpretation of geological, geophysical and petrophysical date, it has been established that oil-and- gas-bearing reservoirs are mainly fractured volcanogenic-sedimentary and carbonate rocks.

The northern part of North Australia is not far from Java and Timor. There are great numbers of influences in the North Western part of Australia from Indonesian region. The coast alligator river area is 200 kilometres east of Darwin, Northern Territory is now 60 kilometres from the coast to the mountain area. The plain area is flat and the water is salty, being tidal on the coast. Further inland the river is fresh water. To day there are few mangroves in this area, but there is evidence that mangroves were more widespread between 6.000 - 3.000 BP. During the wet season the coastal plain is flooded.
