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 petr...
