INTERPRETASI DATA ANOMALI MEDAN MAGNETIK UNTUK MENGIDENTIFIKASI PENINGGALAN KADIPATEN PASIR LUHUR DESA TAMANSARI KARANGLEWAS
Abstract: Magnetic surveying
have been done in the area around of the Carangandul site, District of Karang
lewas, Regent of Banyumas. The research purpose is for identify Kadipaten Pasir
Luhur’s remainder whom maybe buried at around that sites. The total magnetic intensity
data obtained, then be processed, corrected, and reduced so thatbe obtained the
local magnetic anomaly data. Modeling process to magnetic anomaly data with two
dimensions (2D) have been done by utilize Mag2DC for windows software. Based on
the modeling results, be obtained the subsurface lithology section with
magnetic susceptibility values of 0.0141 – 0.0626 cgs units. The interpretation
ofmodeling resultsshow thatin the depth of 0 – 10 meters be found the sand
stone, then in the depth of 10 – 125 meters befound the breccia-andesite rocks,
then in the depth of 125 – 250 meters be found the andesite rocks with insert
of sand, and then in the depth of 250–500 meters be found two pieces of rocks
i.e. breccia-andesite and andesite-basaltic from volcanic lava boulder of
Slamet Volcano which be estimated as the basement inthe research area. Based on
the interpretation resultis not found available distribution of pure andesite
as sites that exist on the surface.
