Presence of oil-and-gas was established for the Palaeogene horizons I, II, IIa, III, IV and for the horizon V of the Upper Campanian+Maastricht Floors.
IIa-pay horizon embedded beyond the regional oil-and-gas beneficial II-horizon of the Palaeogene Bukhara seams (Aruktau horizon) is represented by fissured and unefficient limestone seams in the anhydrite stratum.
Shows of Palaeogene and chalk ledge rocks within the fringes of the basin that are found at relatively high altitude marks and considerable differential of hypsometric marks in relation to the central part of the basin favor the conditions for penetration of water into the ledge pools.

 Cenozoic - Wikipedia, the free encyclopedia
It covers the 65.5 million years since the Cretaceous-Tertiary extinction event at the end of the Cretaceous that marked the demise of the last dinosaurs and the end of the Mesozoic Era.
The Cenozoic is divided into two periods, the Palaeogene and Neogene, and they are in turn divided into epochs.
The Palaeogene consists of the Paleocene, Eocene, and Oligocene epochs, and the Neogene consists of the Miocene, Pliocene, Pleistocene, and Holocene epochs, the last of which is ongoing.

 UGD Entry for Tomsk, Russia
At the base of the Palaeogene complex, there is a consistent aquifer (with a thickness 30-40 m) which is comprised of sands with clay and lignite interlayers.
In northern part of city in Palaeogene complex, piezometric levels were lowered by 5-6 m, while in southern part of city in the Palaeozoic formations, regional levels were lowered by 7-8 m (Pokrovsky et al., 1998).
For example, elevated concentrations of sulphate occurs in Palaeozoic and Palaeogene complexes as result of inflows from higher aquifer horizons and, in Palaeozoic deposits, sulphide oxidation which is enhanced by groundwater extraction.

 Biodiversity Response to Climate Change
The Cenozoic was an important period in Earth's climatic history, since it records the change from greenhouse climates during the early Palaeogene to icehouse climates in the Neogene.
In particular, the record of this major climate transition in the Southern Hemisphere is important because it involves the initiation and development of the Antarctic ice sheet, which now exerts a major control on our global climate.
Fossil plants from Palaeogene strata on Seymour Island, Antarctica, are being investigated to determine the nature of vegetation response to climate change in southern high latitudes.

 Tectonics of SW Bulgaria: general idea - Rhodope Geodynamic Hazards
The Palaeogene and early Neogene tectonics, although predominantly extensional, formed also some thrust structures (or reactivated older ones) in short compressional phases, or in result of gravity phenomena.
The complex assemblage of pre-Palaeogene tectonic units and superunits, and Palaeogene and Neogene block structures (grabens and horsts, often complicated by thrusts and intrusive bodies and lava flows) is situated obliquely and discordantly to the pre-Late Cretaceous sedimentation environments and structures.

Mesozoic and Palaeogene continental and marine sediments were deposited in a number of rift basins on the coming continental shelves.
Around the time of continental break-up in the Palaeogene, large volumes of volcanic rocks were also deposited, both in the present shelf areas and on the exposed continental margins of Greenland and Europe, as reviewed by Upton (1988) and Saunders et aL (1997).
The rocks exposed and drilled in the Faeroe Islands are Palaeogene tholeiitic flood basalts with an overall chemical character similar to the Palaeogene flood basalts that occur in central East Greenland.

 Geology of the Channel Tunnel
The structural control exercised on the Mesozoic and Palaeogene rocks by the largely concealed Palaeozoic rocks of the London-Brabant massif was not fully documented (Shephard-Thorn et al, 1972) even by the time of the later site investigations.
The sea-bed outcrops of the Jurassic, Cretaceous and Palaeogene rocks are adequately defined by recent research involving bottom sampling, seismic profiling and some shallow boreholes, but in general the stratigraphy is less well known than for the onshore successions.
In Kent and Sussex, the Weald Anticline is bounded to the north and south by the North and South Downs respectively; its continuation across the Channel is seen in the Boulonnais, where it is delimited by the horseshoe-shaped Chalk uplands of the Haut Boulonnais.

Palaeogene reservoirs in the North Sea have particularly well developed evidence of sand remobilisation; problems associated with the prediction of reservoir quality and productivity in these strata are the catalysts for this proposal.
The aims of the research are howeve genereic and thus may be applied globally to reservoirs of any stratigraphic age.
Using a multi-disciplinary approach the project aims to document the characterisitis of remobilised sands and to understand their causes and consequences.

There is still controversy and confusion regarding the form of the Top Chalk surface in the Early Palaeogene.
This question is important in terms of reconstructing Palaeogene palaeogeography and palaeodrainage patterns.
The balance of evidence suggests that geological structure did not have major impact on Palaeogene deposition and drainage pattern: the Hampshire and London basins merely preserve remnants of a broader coastal plain and shallow shelf depositional system.

The ages of these silcretised surfaces are not well constrained, but most are probably Palaeogene in age.
Southern African coastal surfaces planed by Palaeogene and Neogene fluvial activity and relative sea-level highstands underwent subsequent deep reweathering, kaolinisation and extensive pedocretion.
The present (Flandrian) eustatic highstand is currently stripping up to 70 m of weathered and partly silcretised basement and Cenozoic strata along the west.

micropalaeontology, necessary to date the widespread, epicontinental marine sediments of Palaeogene age by modern micropalaeontological methods necessary to support the correlation of sediments with sequence stratigraphy in the exploration of geological resources.
This will have to be completed by fieldwork focusing on gaps in the collected record according to the outcome of preliminary work on the collections available today.
The following results are expected: revision of biostratigraphic zonal age attributed to the Palaeogene sedimentary series in key sections in Ukraine, Crimea, Caucasus, Mangyshlak and northern Aral Sea, and in the Tadjikistan depression and the production of range charts; palaeobiogeographic interpretation of results, including palaeooceanographic patterns as worked out by the INTAS project 93-2509.

Consequently, this geological interval in Earth history frequently is cited as a potential analogue for future anthropogenically-forced climate change and is of importance in terms of obtaining an improved understanding of the possible modes of operation of Earth's ocean—climate system under greenhouse-climate conditions.
The physical and chemical states of the Cretaceous and early Palaeogene oceans are poorly understood, however, compared to more recent times in Earth history.
The objectives of the project, therefore, are to generate integrated geochemical datasets in order to quantify better the physical and chemical characteristics of the mid-Cretaceous to early Palaeogene oceans.

 MOLECULES, MORPHOLOGY, AND THE PHYLOGENETIC POSITION OF LAURASIAN AND GONDWANAN "CONDYLARTHS"   (Site not responding. Last check: 2007-10-21)
Over the course of the past decade, molecular phylogenetic analyses have revolutionized our understanding of the higher-level interrelationships of placental mammals, and have provided an entirely new context within which the late Cretaceous and early Palaeogene placental radiation must now be interpreted (e.g., Murphy et al., 2001).
One novel hypothesis derived from this work is the idea that the recently recognized supraordinal clade Afrotheria (containing elephants, sea cows, hyraxes, elephant-shrews, aardvarks, tenrecs, and golden moles) originated on the Afro-Arabian landmass and evolved in isolation there through the latest Cretaceous and much of the early Cenozoic.
However a recent study (Asher et al., 2004) suggested that some of the "condylarths" from the Laurasian Palaeogene (hyopsodontids and phenacodontids) that have traditionally been allied with the laurasiatherian artiodactyls and perissodactyls are actually primitive members of the afrotherian radiation.

The Island's beaches are the best places to collect fossils and as many of these are located in the Island's Areas of Outstanding Natural Beauty fossil collecting here is a special and enjoyable experience at any time of year.
In some places beautifully preserved leaves can also be found and in others even the delicate wings and bodies of insects are preserved.
Following the time when these fossils were first buried there is a long gap in the rock and fossil record during which time the Cretaceous and Palaeogene strata were folded by forces which further south produced the Alpine mountain range.

One of the most important problems presented by the determination of individual species of fossil leaves is connected with the complex classification (species, genus and family) of traditional determinations of architecture and leaf morphology and also of cuticular studies.
In spite of these problems general palaeobotanical conclusions are very close to composition of classic Palaeogene palaeo-phytoassociations.
