Abstract: Gravity and aeromagnetic anomalies of
a local area in northern central Turkey obtained from the General Directorate
of Mineral Research and Exploration of Turkey (MTA) used to estimate the
source body magnetization, which can also reveal the remanent magnetization
component. Rocks collected from the outcrops suggest a mafic origin for the
gravity and magnetic anomalies. Possible paleopole positions of latitude from
-44.05o N to -27.480 N and longitude from 11.950 W
to 23.400 W are calculated for varying induced intensity ranges.
Koenigsberger ratios (Q) are calculated for inclination and declination
angles of remanent magnetization for paleopole ranges to monitor the
reliability of the paleopole positions. The present day geomagnetic pole
position using the proposed method is estimated at approximately geographic
latitude and longitude of 84.90 N and 72.80 W,
respectively. This demonstrates the reliability of the existing mathematical
algorithms. Calculated paleopole positions in the study area indicate that
these formations are rotated about 500 in an anticlockwise
direction as suggested by previous researchers in central Turkey. |
