MODULUSINVERSIONOFTHREE-COMPONENTBOREHOLEMAGNETICDATA
摘要
Abstract
Itisusuallynecessarytoconsiderthemagnetizationdirectionofthemagneticbodyintheinterpretationofthree-component boreholemagneticdata;however,itisratherdifficulttodeterminethemagnetizationdirectionunderthestrongeffectofremnantmag-netizationordemagnetization.Themodulusofmagneticanomalyisnotdependentorinsignificantlydependentonthemagnetizationdi-rection,andmoduluscanbecalculateddirectlybyusingthree-componentboreholemagneticdata.Theauthorshencetriedtoinverse themodelparameterswiththemodulusofthree-componentboreholemagneticdata.First,thevalueofthemoduluswascalculatedbyu-singthree-componentboreholemagneticdata.Then,thegeometricalandmagneticparametersof2Dtabularbodyandverticalcube wereinversedwiththemodulusdata.Finally,thismethodwasappliedtotheboreholemagneticdataofanironoremineinXinjiang.
