Estimating the parameters of simple models from two-component on-time airborne electromagnetic data

The horizontal and vertical components of the on-time electromagnetic (EM) response can be used to estimate parameters simple models like thin sheets, half-spaces, sheets over a lower half-space two-layer model. formulae in these methods are valid areas where is essentially proportional conductivity or conductance, so called "resistive limit". thin-sheet combined give an for below thick sheet that might reasonable whole survey area. With this estimation equation solver thickness overlying This latter approach seemed most appropriate Russell South area Athabasca Basin, Canada, GEOTEM data has been collected. output algorithm was generally stable. Although it did not always reliably reproduce overburden thicknesses as measured set reference drill holes, relatively conductive areas.
