Zusammenfassung:
The Mallik Anticline is a geologic structure in the Mackenzie Delta in the
Canadian Arctic. Tectonics throughout the Cenozoic, with compressional phases
in the early Eocene to the late Miocene, formed this large, domed structure
that is today an important source of hydrocarbons. Gas hydrates occur in the
clastic sedimentary rocks of the Oligocene to Pleistocene Kugmallite, Mackenzie
Bay, and Iperk sequences, which were essentially formed by deltaic processes.
The presence of hydrocarbon gases within the permafrost zone in the Canadian
Arctic has led to extensive exploration and production activities in the region
since the mid-1960s, and the investigations by geologists and geophysicists
have already been published in numerous scientific articles to date.
This report describes the implementation of the first field-scale 3D static
geologic model of the Mallik site, which was created using data from well logs
and 2D seismic reflection profiles. The dataset related to this report provides
elevation depths and thickness data of the three distinct sequence boundaries
Kugmallit-Richards, Mackenzie Bay-Kugmallit and Iperk-Mackenzie Bay as well
as fault data from the Mallik site.
