摘要/Abstract

摘要： 本文通过测量唐山断裂带南西段王兰庄和北东段巍峰山的土壤气Rn和CO₂浓度, 探讨了Rn和CO₂浓度的空间分布特征及其与断裂活动的关系。测量结果显示, 王兰庄剖面和巍峰山剖面土壤气Rn浓度范围分别为691~57 671 Bq/m³和471~32 739 Bq/m³, CO₂浓度范围分别为0.17%~7.21%和0.08%~1.71%。两个剖面Rn和CO₂浓度均高于区域背景值, 这与唐山断裂带断层的开放状态有关。 Rn和CO₂释放强度(K_Q)在王兰庄剖面分别为2.90和4.04, 在巍峰山剖面释放强度分别为0.90和0.99。王兰庄剖面测线中部土壤气浓度明显高于两端, 而巍峰山剖面测线中部与两端浓度平均值相近, 这种浓度空间分布特征的差异主要是断层破碎程度不同所致。巍峰山剖面土壤气Rn浓度水平较高, 地球物理学研究发现此区域应力值高, 断层活动性较强, 表明土壤气Rn浓度与断层活动性有着密切的关系。

Abstract: We discussed the geochemical characteristics of soil gas Rn and CO₂ concentration and the correlation between the spatial variation of soil gas and tectonic activity, based on the measurements of Rn and CO₂ concentrations in the south-west (Wanglanzhuang) and north-east (Weifengshan) segments of the Tangshan fault zone. The results show that the concentration range of Rn in Wanglanzhuang and Weifengshan are respectively 691 to 57671 Bq/m³ and 471 to 32739 Bq/m³, while the concentration range of CO₂ are respectively 0.17 to 7.21% and 0.08 to 1.71%. The concentrations in these two profiles are higher than the regional background values, which may be caused by the open state of fault in the Tangshan area. The release intensity (K_Q) of soil gas in these two profiles is different. K_Q of Rn and CO₂ is 2.90 and 4.04 respectively in Wanglanzhuang Profile, and is 0.90、0.99 respectively in Weifengshan Profile. This illustrates that the concentration in the middle part of Weifengshan Profile is much higher than that at the both ends, while in Weifengshan Profile, the concentration of each part is consistent. The soil gas geochemical results show that the variations of soil gas spatial distribution may be attributed to the different degree of fault fragmentation in the profiles. The higher the regional stress, the higher the fault activity and the concentrations of Rn in Weifengshan Profile. This indicates that the concentration of Rn is closely related to the activity of faults.
