DESCRIPTIVE NOTESThe aircraft (C-GILU) is equipped with the Geuterrux GEOTEM" airborne EM systorr, a Van an single cell, split beam cesium vapour magretometer. and a MADACS cigital cala accuisition system. GEOTEM " is a digital high power time-domain CM system with a peak nomen: of 4.5 x 10* Am*. Current wave form is a half sine wave with a pulse duration of 17011 rmcrosRnnnris and a repetition -ale of 300 pulses per second, The horizontal axis receiver coil is nominally 107 met'es bemnd ard 80 metres below the vertical axis transmitter loop

The quantitative interpretation of the GEOTFM' data is accomplished by comparing the resultant FM responses witn lypc curves obtained from mathematical model studies. The channel amplitude ratios o' a response are mainly a function of the conductance nf its source The response magnitude varies with conductor de p Lh and g com c li y The relcrcnco nomogram for 1he su'vey is a vertical plate, produced from a thin sheet model with 600 rr stnke length and 300 rr depth extent, located at ground su r facoThe GtlOTEM'5 System will respond to condLCt've overburden, near-sur'ace horzonlal cunciuctmc layers uullural sources and bedrock conducing. Discri'iiinatiun ol nai.iirai conductors is based on the "ate of transient decay, magnetic correlation and the response shape, together with the response pattern and topograpny.Cultu-al responses aiu identifiable by examining the power line monitor and the flight track film lo locale cultural sources.

The magnetic data were: (1) co-reeled for diurnal variations by subtraction o' the digitally recorded base station magnetic data, (iil levelled lo the tirj line data, (iii'i interpolated ontu a regular O 25 cm gud, al the map scale uf 1.20 000, using a modified Akima'" technique. No correction has been made fo' regional variation of the earth's magnetic field
