摘　　要：易门-罗茨断裂带是多期活动的大规模断裂带,以易门-罗茨断裂为主断裂。在禄劝县皎西一带,断裂带控制了南北向的串珠状第四系盆地,盆地内第四纪沉积物厚数米至数十米,主要的控盆隐伏断裂位置、特征难以确定。采用地质调查与土壤氡测量相结合的方法,查明了区内控盆隐伏断裂的位置、产状、宽度等。调查结果与地貌和区域构造特征吻合较好,因此认为,土壤氡测量适用于山间盆地内隐伏活动断裂的调查。Yimen-Luoci fault is the main fault of the Yimen-Luoci faulted belt, which is characterized by large scale multistage activities. It is difficult to determine the location and features of the basin-controlling fault due to the fact that loose sediments several to tens of meters in thickness are widely spread over the NS-trending beaded-like Quaternary basins, conn＇olled by Yimen-Luoci faulted belt in Jiaoxi Town, Luquan County, Yunnan Province. The position, width and attitude of the basin-controlling buried fault were found by means of geological survey and gas radon measuring in this study. The measuring result is well consistent with topographical features and regional tectonics, and hence the authors hold that gas radon measuring is suitable for investigation of buried active faults in intermount basin.
