YGS is continuing to collect new gravity data, upgrading the current gravity database for Yukon with more closely spaced (~2km) stations. A survey is planned for early winter 2015; the survey area is still being identified. The survey will be funded by CanNor.
3D Inversion of magnetic and gravity data, southwestern Yukon
Mira Geoscience has been contracted to undertake a “value-added” study that inverts magnetic, gravity, bedrock geology and physical rock property data to generate constrained 3-dimensional geologic models. The study area covers the northern part of Whitehorse trough and extends westward across a portion of the Yukon Tanana terrane to north Aishihik Lake, where recent bedrock mapping (Coast Belt
and Whitehorse trough areas ), aeromagnetic1
surveys provide modern constraints for the models.
