| 摘 要： | 西藏羌塘北部热觉茶卡组的 类动物群共3属11种（不含未定种），包括：Palaeofusulina sinensis Sheng， P. fusiformis Sheng，P. nana Likharev, P. laxa Sheng, P. wangi Sheng, P. minima Sheng et Chang, P. simplex Sheng et Chang, Parananlingella acervula (Sheng et Rui)， Reichelina changhsingensis Sheng et Chang, R. pulchra K. M.-Maclay， R. gaqoiensis Wang, Sheng et Zhang。根据 类沿剖面的分布，建立了Palaeofusulina 带，由下至上划分为2个亚带：Palaeofusulina minima亚带和Palaeofusulina sinensis亚带。该 类化石带属种丰度高，所含的 类动物群属华夏特提斯型分子，为晚二叠世的代表分子和典型分子，与中国华南长兴阶 类化石带可进行对比。 |

| Abstract: | The Late Permian in the Northern Qiangtang area was named Raggyorcaka Formation, which contains abundant fusulinds such as Palaeofusulina sinensis Sheng, P. fusiformis Sheng, P. nana Likharev, P. laxa Sheng, P. wangi Sheng, P. minima Sheng et Chang, P. simplex Sheng et Chang, Parananlingella acervula (Sheng et Rui), Reichelina changhsingensis Sheng et Chang, R. pulchra K.M.-Maclay and R. gaqoiensis Wang, Sheng et Zhang. One fusulind zone named Palaeofusulina zone has been established, comprising two sub-zones: Palaeofusulina minima sub-zone and Palaeofusulina sinensis sub-zone. This study area is abundant in different Fusulinds fossil varieties, which all belong to Cathaysian Tethys type in representative of Late Permian, thus it can be correlated with the Changxing Fusulinds fossil belt in South China. |
