- Abstract:
-
Basing on the real measuring results of gas radon at 23 measuring fault gas profiles on Tianjian South Fault and Tianjian North Fault, we obtained the location of two faults. The exploration results also show that the Tianjian North Fault extends to the vicinity of Tangguantun Village in Jinghai County along its original location, but the Tianjian South Fault has been separated in two directions to extend to north in Chaomidian-Muchang profile, and more exploration work should be done for determining the extending position. We analyzed 23 soil radon measurement results and found that the abnormal patterns of soil radon are inconsistent, and the anomaly is not necessarily appearing above the fault. Using the highest value of oil radon anomaly and the average value of anomaly value and H value, we analyzed synthetically the segment characteristic of the activity of Tianjin Fault and obtained that the segment characteristic of the activity of Tianjian South Fault and Tianjian North Fault were not obvious.
