Method of interpreting seismic reflection data in the Vilyui Syncline

The interpretation of observations obtained from geophysical prospecting is complicated in permafrost regions by the low ground temperatures and high ice contents causing higher seismic velocities and electrical resistivities than in thawed strata. This paper deals with seismic surveying in the Vily...

Description
Summary:The interpretation of observations obtained from geophysical prospecting is complicated in permafrost regions by the low ground temperatures and high ice contents causing higher seismic velocities and electrical resistivities than in thawed strata. This paper deals with seismic surveying in the Vilyiu syncline located to the west of the Lena River in Eastern Siberia where the permafrost varies in thickness from 200 to 600 metres. Information is presented on seismic velocities occurring in different types of rock with varying permafrost conditions. Peer reviewed: No NRC publication: Yes
