Report on 1D Inversion Modelling of the QUEST West Helicopter-Borne AeroTEM System Electromagnetic Data by Aeroquest Surveys
Note: This survey consists of two blocks (Block 1 in UTM Zone 9 and Block 2 in UTM Zone 10), which are subdivided into smaller blocks. Six infill blocks were also flown over known mineralization. The maps below show the QUEST-West survey blocks (Blocks 1 and 2), sub-blocks and the 6 infill survey blocks. Click on the maps for a larger view.
UBC-GIF EM1DTM files are available by request, please email us at and we will send you a DVD (4GB).
Geoscience BC Report 2009-18 is part of the QUEST-West project, which covers over 40,000 square kilometers from Vanderhoof and Fort St. James to Terrace and Kitimat.
This report describes the EM1DTM Inversion modelling carried out on the AeroTEM electromagnetic data from Geoscience BC's QUEST West Project. Data collected over the two large-scale blocks of the QUEST West area and the six infill areas (Huckleberry, Bell, Granisle, Equity Silver, Endako and Morrision) were inverted to produce pseudo 3D resistivity models. The UBC-GIF EM1DTM code was used to produce a 1D resistivity model at each sounding location. These 1D models were then concatenated to produce a 2D image of the subsurface along the survey lines. Two-dimensional lines were then displayed in 3D space.
