Methods in Palaeomagnetism (II): Calculation and Plotting of Palaeomagnetic Pole Positions

고자기학(古磁氣學)의 방법(方法)(II) : 고자기학적(古磁氣學的) 측정자료로부터 자북(磁北)의 위치를 도시하는 방법

Palaeomagnetic studies accompany calculation and plotting of pole position. This paper explains three graphical methods for the determination of pole position and plotting problem. It also derives the numerical formula for pole calculation and explains the method how the pole plotted on the rear hemisphere can be transformed to the frontal hemisphere, which is not clarified elsewhere.
