Diamond exloration with airship-borne gravity gradiometer

Abstract

Early stage diamond exploration commences with the careful selection of geophysical anomalies that are characteristic of kimberlites. However, it is also essential to map the structural controls on kimberlites and the background geology. When used in conjunction with the expected age of emplacement an understanding of the geology helps determine the degree of kimberlite preservation. This may impact on the economics of a discovery but also provides boundaries on the physical property contrast between the target body and host rock.
