摘要
在三道岭原石炭系中采到大量腕足类化石,其上部灰岩的时代应为D_1—D_2,其下部泥岩的时代应为S_3—D_1.
Lots of fossiles of Brachiopoda have been collected in the previous Carbonife-rous System 30 km west of Sandaoling, Hami. Base on the fossiles, the limestone of the upper part of the system is considered to be early-middle Devonian and the mudstone of the lower part to be the latter Silurian to early Devonian.
