The Geochemical Features of Radon and Mercury on Lanzhou Jinchengguan Active Fault

摘要:

分析了兰州金城关断裂带土壤气氡、汞的地球化学特征及其与断层出露位置和断层产状的关系,给出金城关断裂不同段的断层性质.讨论了利用断层带土壤气寻找隐伏活断层以及判断活断层性质的依据和方法.

Abstract:

The geochemical features of radon and mercury on Lanzhou Jinchengguan and the relation with fault position and occurrence are analyzed. The fault characters segments of Jinchengguan fault are also determined. Meanwhile, the main evidences of searching active fault by using fault gases are discussed.
