Abstract

Tehnike otkrivanja i poboljšanja rubova podataka potencijalnih polja (gravitacijski i magnetski podaci) korisni su alati za pronalaženje mjesta anomalija u dubini. Nedavno su ove metode, uključujući filtre na bazi derivata, lokalne fazne filtre i tehnike temeljene na statistikama, sve više naširoko se koristi u rješavanju geoloških problema, poput identificiranja podzemnih rasjeda, kontakata i drugih tektonskih značajki. Ipak, opće metode možda neće pružiti značajne rezultate za potencijalne terenske podatke s jakom bukom. Da bismo prevladali ove nedostatke, predstavljamo novu metodu pod nazivom Varimax Norm (VariNorm) s pomičnim prozorom za procjenu mjesta potencijalnih podataka polja. Ispitivanja izvedena na sintetičkim i poljskim podacima u rudnom području Tonling pokazuju da metoda ne zahtijeva vodoravne ili okomite izračune izvedenih derivata bilo kojeg reda, odolijeva buci u prirodi i nadmašuje ostale tradicionalne metode u jakom okruženju buke.
