Nan suture in northern Thailand, representing a complex zone with complex geology and structures, has been selected for airborne geophysical investiga-tions. The suture has been widely accepted as an early Triassic collision zone between Shan-Thai and Indo-china microcontinental blocks. Our field data suggest the occurrence of a mélange zone in response to com-pression tectonics. Moreover, previous petrochemical and field investigations suggest that the Nan suture may have been formed as a result of a subduction zone.  相似文献
