Abstract

ABSTRACT: Ajung Village District of Balangan, astronomically are located 114
º 50'31'' 115 ° 50'24'' E and 2 º 1'31'' - 2 ° 35'58'' S. Based on the geological
map, the Ajung Village District Balangan is Haruyan formation, Ultramafic Rocks
and Granodiorit. The erosion of Ultramafic rocks, especially serpentinit undergo
chemical decomposition and accumulation of iron ore. Since the potential of iron
ore in Ajung Village is not certain then in this study the authors conducted a
study to determine the potential depth and content of iron ore by using 3D
geoelectric Dipole Dipole configuration, Atomic Absorption Spectrophotometer
(AAS) and X-ray flourescence (XRF). The results of field measurements 3D
geoelectric method Dipole Dipole configurations with the potential depth of ± 0
to 2.05 meters in the form of chunks of rock with prices between 1594 -2442
Ohm.meter resistivity. The average Fe content of elements in the iron ore from
Ajung village, District Balangan by laboratory analysis using AAS was 50.01%,
while 94.82% are using XRF.
Keywords: iron ore, geoelectric, AAS, XRF
