摘　　要：配合青藏高原油气资源战略选区调查与评价工作,在西藏地区措勤盆地开展了大地电磁测深工作。根据测量结果对盆地边界、基底埋深和盆地基本构造格架给出了初步解释;提出了措勤盆地应按中生代和古生代盆地分别进行评价的新认识;指出班公湖~怒江缝合带南界断裂为一由北向南的逆冲推覆带,其下可能有较新时代的沉积地层。测量结果对认识措勤盆地结构构造,盆地油气资源潜力评价提供了有意义的依据。As a part of the national project " Investigation and Evaluation of Strategic Prospect for Oil & Gas and Target Area Selection in Tibet Plateau", a magnetotelluric ( MT) sounding was carried out in the Cogên basin. The preliminary interpretation for the boundary, basement depth and structural framework of the basin was made, and with a new idea of evaluating the prospect based separately on Mesozoic and Upper Paleozoic basins proposed. It was inferred that the southern boundary of Bangong Lake-Nujiang sutur...
