The magnetic susceptibility (X) and natural remnant magnetization (NRM) of 6 core samples and 48 surface soil samples from the Shilong and the RongqiGtuzhou areas, the two industrial areas of the Zhujiang River Delta, are determined.
对珠江三角洲东莞石龙、顺德容奇—桂洲两工业区的土壤磁性进行初步研究，获得两地区6个柱样及48个表层样品的磁化率（X）和天然剩余磁化强度（NRM）的结果，石龙地区的X，NRM的垂直变化平均值分别为10。
