1.GENERALINFORMATION

TheRT‐1MagneticSusceptibilityMeterisdesignedtomeasurethemagneticsusceptibilityof
rockoutcrops,rocksamplesanddrillcore.

Themineralthatlargelygovernsthemagneticbehaviourofarock,andwhichaccountsformost
ofthesusceptibilityobserved,ismagnetite.Thesusceptibilityofmagnetitedependsonseveral
factors,suchastheintensityofthemagnetisingfield,thechemicalcompositionofthe
magnetiteanditsgrainsize.Susceptibilitycan,however,beusedtodeterminethemagnetic
abundance,providedthatthedependencebetweensusceptibilityandmagneticabundanceis
known.


TheRT‐1isdesignedasaonepieceinstrumentwithagraphicsdisplayforthepresentationof
themagneticsusceptibilityvaluesinbothdigitalandanalogformat.Anaudibletoneofvarying
frequencyrelatedtothevalueallowstheoperatortofindthepeakreadingusingthegraphical
displayorthehighestfrequencysoundandthenrecordadigitalvalue.Ithassolid‐state
memorywiththeabilitytostorereadingsintogroupsandlabel(withaflag)individualreadings.
