Introduction: The purpose of this paper is to determinate the position, depth, dip direction and
dip angle the faults in the South region of Vietnam from the total magnetic intensity anomalies, that
reduced to the magnetic pole (RTP). Methods: Based on the Oasis Montaj software, we proposed
a new way to compute the positions and the depth to the top of the faults by combining the Tilt
angle and the Euler deconvolution methods. In addition, the angle and direction of the dip of
theses faults were also determined by considering maximum of the total horizontal derivative of
the RTP upward continuation at the different height levels. Results: The results show that there
are 12 faults along the longitudinal direction, latitudinal direction, Northwest— Southeast direction
and Northeast — Southwest direction with the mazimum depth is about 3100 m and the dip angle
changes in the range of 65-82◦
. Conclusion: These indicate that these methods are valuable tools
for specifying the characteristics of geology, contribute to give and confirm the useful information
on geological structure in the South region of Vietnam.
