Metodologia exploratória para demilitação de condutos vulcânicos kimberlíticos com o uso do método CSAMT, MG, Brasil

Abstract: ABSTRACT.In the present work we present a case history where the Controlled Source Audiomagnetotelluric -CSAMT method have been applied to unveil the geological structure of Regis, a kimberlite pipe in Minas Gerais state, Brazil. The kimberlite outcrops were discovered in the late 1970's by surface geological mapping.Three CSAMT profiles, two striking north-south and the third striking east-west were acquired crossing the kimberlite crater. The Stratagem CSAMT sounding stations, with electrodes and coils laid … Show more

“…2) were collected in two different field surveys. In the first one, 54 AMT stations were acquired along three main profiles crossing the Regis kimberlite and allowed a 2D interpretation of the pipe (La Terra et al, 2010). In the second campaign, 57 new stations were acquired in the same area with the goal of having a spatial data distribution suitable for the 3D interpretation, the main subject of this study.…”

“…Esse é o caso do lineamento azimute 125°. Como forma de reduzir à inerente ambiguidade do processo de interpretação da inversão foi realizada uma modelagem 2D integrada, utilizando-se como vínculos informação a priori advinda dos estudos geofísicos independentes de magnetometria (MENEZES e LA TERRA, 2011), e de eletromagnetometria (LA TERRA et al, 2010e LA TERRA e MENEZES, 2012.…”
