摘要
<正>The tectonic relationship between the Alxa Block and the North China Craton has long been controversial.The Helanshan area lies at the western margin of the Ordos Block and east of the Alxa Block(Fig.1),and it contains rocks of the lower Zhengmuguan and upper Tuerkeng formations that belong to the
