摘要: 本文根据有关地层的观察。提出北秦岭在加里东褶皱的基础上,有一广泛的泥盆纪时期的海浸,最后形成华力西褶皱带。

Abstract: Observations of related strata in the North Qinling Mountains and recent regional geological surveys of the area indicate that a Devonian sea trough developed on the basis of the Caledonian fold belt in the North Qinling. It was connected with the Central Qinlng Devonian sea trough. By the end of the Devonian. the fold inversion began, forming a Yariscan fold belt, This paper furnishes grounds for the determination of this fold belt.
