| 摘 要： | 五村-移山地区晚三叠世地层发育齐全，并在中咱地块边缘至甘孜-理塘结合带之间构成一个较为完整的沉积盆地。中甸、格咱和弥里淌三条平行控制性断裂将盆地由西向东依次横向分割成中咱微大陆五村台地边缘三角洲、哈工弧后断陷盆地、属都火山复理石盆地和尼汝弧前斜坡(盆地)。在上述4种构造-相区中沉积了各具特色的沉积物，具有不同基本层序结构、不同生物组合及沉积相特征。显示盆地经历下降-抬升-下降-抬升两个周期性演化过程。 |
| 关 键 词： | 台地边缘潮坪相 弧后及弧间盆地 弧前斜坡-盆地 晚三叠世 五村-移山区 |

| Abstract: | The Late Triassic strata are well developed in Wucun-Yishan area of Zhongdian. A complete sedimentary basin was formed between the margin of Zhongza Massif and Ganzi-Litang connection belt. The 3 parallel controlling faults of zhongdian, Geza and Militang divide this basin into the Wucun Delta of platform margin of Zhongza Microcontinent, the Hagong fault sag back-arc, the Shudu volcanic flysch basin and the Niru forearc slope(basin) from west to the east. The various distinctive sediments are deposited in these 4 structural facies regions, which have different structures of basic stratigraphic sequence, different biological assemblages and sedimetary facies characteristics and show the basin experienced 2 periodic depression-rising-depression-rising evolution processes. |
| Keywords: | Tidal Flat Facies of Platform Margin Back-arc and Interarc Basin Fore-arc Slope-Basin Late Triassic Zhongdian Area |
