Fig. 4: Relationship between the average magnetic susceptibility and Rb content of the bricks used in the surveyed temples on the summit of Kulen Mountain.

Based on the average magnetic susceptibility and Rb content, the surveyed temples can be divided into three groups. The temples classified in Group A are enclosed in a red square frame, the temples in Group B are enclosed in a blue square frame, and the temples in Group C are enclosed in a green square frame.
