| 摘 要： | 塔里木盆地北部萨瓦甫齐及塔里克地区4个样品的磷灰石裂变径迹测年以及热史反演结果显示，两个地区的隆升时代不同，其中萨瓦甫齐地区裂变径迹年龄为3．5～3．9Ma，而塔里克地区的裂变径迹年龄为53～59Ma。热史分析揭示出岩体至少记录了自晚白垩世以来的3个显著冷却阶段。同时，结合前人对塔北中新生代隆升剥蚀研究结果，重点对塔北地区中新生代构造隆升阶段进行了详细研究与划分，结合新疆中新生代砂岩型铀成矿年龄，提出了对塔北地区中新生代构造演化与砂岩型铀成矿作用的新认识。

| Abstract: | The apatite fission track dating and inversion result of geological thermal history of four rock specimens from Sawafuqi area and Talike area in northern Tarim Basin show that two areas uplifted at different ages. The apatite fission track ages of Sawafuqi range from 3.5 to 3.9 Ma, while the ages of Talike range from 53 to 59 Ma. The thermal history recorded by rock samples reveals that there are at least three prominent cooling phases since Late Cretaceous epoch. Detailed study was made on the division of uplifting stages during Mesozoic and Cenozoic tectonic evolution with the existing data in northern Tarim area. And new ideas on tectonic evolution and sandstone-type uranium mineralization have been put forward by combining with the sandstone-type uranium mineralization ages in this area. |
