摘　　要：利用遥感地质解译以及土壤地球化学测量和地气测量,发现沿四川绵竹市和什邡市之间的石亭江发育走滑断裂。它们走向北西,雁行斜列,左行走滑。在两条主要左行走滑断裂的右侧叠覆区,两条主断裂第四纪的左行走滑运动产生一个胚胎期的菱形断陷。石亭江菱形断陷中可能形成了与断裂有关的地热系统,而浅层天然气可能沿断裂泄漏了。It has been found that there are strike-slip downfaults along the Shiting River between the Shifang City and Mianzhu City by the remote-sensing geological interpritation and geochemical and geogas surveys. They are all northwest strikes, echelons and left-lateral strike-slips. In the overlap part of the right side of two main faults, the left-lateral strike-slip movement of them in Quaternary has formed the embryonic rhombochasm. In the Shiting River rhombochasm, the geothermal system related to the faults may have been formed, and the shallow gas may have been leakaged by the faults.
