description |
The continental organic matter deposited in the deep basins is little described and represents a definite interest for the petroleum industry. Understanding the sedimentary processes that allow the deposit and preservation of this organic material of terrestrial origin in the deep basins is fundamental. During the Palaeogene, a period of glacial transition to icehouse, the Mackenzie Delta, located in the Arctic Basin, receives and maintains continental organic matter from the continent. What is the stratigraphic and climatic context that made possible the export of continental organic matter? Initially, the sedimentary study of the basin showed a mixed mixture dominated by the fluviatile process, with less influence of the process of storms and tides. This model of facies associated with the study of the logs of wells available in the zone made it possible to propose a model of electrical appliances of the wells of the basin and to characterize the sedimentary sequences of the delta to evolve over time and to demonstrate its migration to Beginning of the Paleogene in response to the establishment of the Brooks and Rocky Ranges. Despite the contradictory biostratigraphic constraints that had to be re-evaluated and poor quality seismic data and strongly impacted by the contemporary deformation of the Brooks chain, it is possible to propose a stratigraphic and sedimentological division along two land-sea transects. Paleogeographic series of the Mackenzie Delta. The sedimentary study of the basin showed the presence of influence of the tidal process in the internal zone of the Arctic Basin. The common presence of pollen from Avicenna and Nypa showed the existence of a mangrove well established in the Arctic domain during the Palaeogene with associated temperatures of at least 18-20 ° C. The deposits of organic matter are in the Almost all of continental origin of the Mackenzie Delta. This organic matter is of two types: (1) deposits of coal deposited during the period when the mangrove develops and (2) deposits ... |
