Abstract
Summary
A VTEM survey was flown over the Tli Kwi Cho kimberlite complex in 2004. The voltage data turns negative over the two kimberlitic targets (DO-18 and DO-27). The data have been transferred to Aarhus Geophysics in order to be inverted using the Cole-Cole model. The inversion of the data allowed recovery of chargeable and conductive material, which coincides with the pyroclastic and partially volcaniclastic facies of the DO-27 kimberlite. Further the TMI data collected during the same airborne survey have been inverted using 3D inversion code, then all physical properties were combined together and populated a same mesh, then the properties were clustered to yiled a 3D pseudo-lithology distribution.
