Kimberlite Exploration at Low Magnetic Latitudes. Case Study at Serra da Canastra, Brazil

Airborne magnetic data from Serra da Canastra diamondiferous province is used to identify possible kimberlite signatures. Serra da Canastra is located in the central portion of the Brazilian territory within a low magnetic latitude area. <br>The interpretation strategy was based on the joint analysis of analytic signal and Euler deconvolution. A selected kimberlite target should have a roughly circular analytical signal anomaly coincident with a depth (0 – 200 m) and structural (N=2) <br>constrained Euler solution. The proposed approach led to ecognition of previously known pipes and new targets were evidenced.
