Inverse modeling using geomagnetic data of field camp geophysics in Karangsambung (2005-2019)

Abstract Geomagnetic data from field camp surveys in Karangsambung 2005-2019 were collected and merged. Before 2020 (the restriction of Covid-19 pandemic), there are 4713 5984 base observation the study area. The purpose works this paper presenting collection, simple processing, calculation inverse modeling. Fifteen each year acquisition merged with 2017 survey as reference. proton magnetometer corrected geomagnetic regional diurnal variation (using available observation). model for 2.5D is calculated using SW-NE slice sections topographic program was built to recover distribution magnetization contrast surface anomaly. interpretation subsurface should be able analyzed correlated rock susceptibility geological maps From work, values anomaly map shown range -1600 1600 nanoTesla, modeling conducted over Volcanic Breccia part Bukit Brujul area, Basalts Diabas between Geopark Karangsambung-Parangan-Sadang Clay Sadang-Totogan
