摘要
This paper studied the age distribution of detrital zircons of sandstone in Shaleisaierke Formation and Shamaershayi Formation of Carboniferous System using LA-ICPMS U-Pb isotopic age of zircons. The results show that the detrital zircons of Shaleisaierke Formation has a wide range of zircon age from 298 Ma to 2 215 Ma, and distributes mainly between 298 Ma and 344 Ma, with a peak at 305 Ma and a second peak at between 501～538 Ma. In addition, there is also one detrital zircon with an age of 1 354 Ma, and other two detrital zircons with ages of 2 146 Ma and 2 215 Ma. The Shamaershayi Formation has a narrow (280 ～523 Ma) and centralized age distribution (299～358 Ma), with a dominant peak at 345 Ma, and some lesser peaks between 428～450 Ma and 507～523 Ma, respectively.
