| 摘 要： | 松辽盆地东南隆起区基底广泛发育副变质岩,3件样品的SHRIMP锆石U-Pb年龄范围为406~2208Ma,反映了松辽盆地基底源区的复杂性。根据目前有关年代学研究成果,推断1100~2200Ma碎屑锆石可能来源于华北克拉通,而样品中的520Ma的碎屑锆石则可能来源于佳木斯地块。另外,样品的岩石学特征和临近大黑山条垒下二台群具有一定的可比性,推测文中样品可能是大黑山条垒在盆地内的延伸。 |

| Abstract: | In the southeast uplift of the Songliao Basin, the basement develop para-rock widely. In this paper, we obtain extensive age range from 406 Ma to 2 208 Ma from 3 para-rock samples by means of detrital zircon SHRIMP chronology, which suggests that the basement of the Songliao Basin has complex provenance. Combined with previous studies, we suggest that the 1 100-2 200 Ma zircons perhaps originate from the China North Craton, while the zircons of 520 Ma may stem from Jiamusi massif. Besides, the samples' petrological characteristics are compatible with those of the Xia'ertai Group of the neighboring Daheishan Horst and we suggest that the samples are probably the extent of the Daheishan Horst. |
