Geothermal Signatures Using Ground Magnetic And 2-D Resistivity Imaging Methods.
Masters thesis, Perpustakaan Hamzah Sendut.
Abstract
Ground magnetic and 2-D resistivity imaging method are widely used in
geophysical exploration for subsurface identification to study the earth rheology such
as fault process based on the geophysical parameter. Ground magnetic and 2-D
resistivity imaging surveys were conducted to investigate the trend of Seulimeum
fault system and the signature of potential geothermal surface manifestation resulting
from the fault. Four different sites, namely Krueng Raya, Iejue, Lamtamot, and
Tangse were chosen as study area for Seulimeum fault study while two sites; lejue
and Ie-Seu 'Urn were chosen as case study areas in identifying the geothermal
signatures. Ground magnetic method was performed using proton magnetometer
while the 2-D resistivity imaging survey was done using ABEM Terrameter with
Pole-dipole array. The magnetic residual contour map in Krueng Raya locality shows
the dislocation from northwest to southeast (NW-SE) direction with contrast of high
and low magnetic residual ranging from -150 nT to 300 nT which interpreted as the
geological fault. In Iejue site the result shows the contrast of magnetic residual
between -150 nT to 300 nT which indicate as geological fault continuous from
Krueng Raya.
