Title: Recent applications of airborne gravity gradiometry in mineral and petroleum applications; examples and lessons learned

Date/Time: Thursday April 20, 2017 @ 4:30pm

Location: 4th Floor Conference Room, Room 451, 409 Granville St. (UK Building at Granville and Hastings), Vancouver

Abstract:

Three examples from two recent helicopter-borne gravity gradiometry surveys are presented: the first for kimberlites in the Slave Province, the second two from a survey flown for Sedex Pb-Zn-Ag mineralization in the Kechika Trough, BC.

An innovative approach to establishing bathymetry control in a portion of the Canadian Shield is discussed.

We then move on to discuss the critical application of terrain corrections as applied in a relatively rugged survey area. Finally, again in a region of rugged terrain, we address the derivation of the tensor components using Fourier and Equivalent Source methods, and discrepancy in results.
