Basin of northern Russia lies along the western margin of the Urals
Mountains and forms the northernmost foreland basin developed during
the collision of the European and Asian continental plates. The collision
commenced in the Early Carboniferous but the exact timing of the basin's
structural development is complicated by the presence of a series of
north-south trending inverted highs which appear to young from east
to west and span the emplacement of the Urals Mountains.
anticlines points to commencement of inversion in the Visean with the
transition from an eastern passive margin to foredeep around the mid-Permian
but no detailed and reliable picture of the timing of individual events
can be derived from existing data.
This study of the
thermal history of northern Timan-Pechora using AFTA and VR will be
designed to reveal the timing and magnitude of maximum paleotemperatures
of potential and proven source intervals within the basin and so resolve
and quantify events associated with the Uralian collision in each of
the structural regions evaluated. Where possible, estimates of paleogeothermal
gradient will allow amounts of missing section to be determined.
The timing and
magnitude of maximum paleotemperatures is critical for evaluating the
remaining oil potential of each structural domain within the basin and
the amounts of uplift and erosion provide a vital component for the
integrated basin modelling of the region.
will be based on approximately 15 AFTA and up to 40 VR analyses of samples
taken from 12 wells drilled in the following areas:
- The Malozemel-Kolguyev
- The Pechora-Kolva Ridges
- The Khoreyver Depression
- The Varandey-Adzva High
- The Korotaikha Trough
