Early Paleozoic TianshuiWushan tectonic zone is located in the Tianshui area in the eastern Gansu province. It consists mainly of GuanzizhenWushan ophiolite belt in the Cambrian meso to epimetamorphic sedimentaryvolcanic rock series at the active continental margin in the Late CambrianEarly Ordovician Liziyuan Group, islandarc volcanicsedimentary rock series in the Ordovician Caotangou Group, plutonic intrusion and subductioncollision granitoid in the Caledonian. Metabasic volcanic rocks in the Guanzizhen ophiolite belong to NMORB, and metabasic volcanic rocks in the Wushan ophiolite belong to EMORB. They are importance segments of the ocean ridge ophiolite, formed in between 534Ma to 489Ma of Cambrian. Volcanic rocks in the Liziyuan Group mainly formed in forearc basin setting with islandarc or islandarcrelated, and volcanic rocks in the Caotangou Group formed in islandarc setting with subductionrelated. Intermediatebasic igneous complexes of Liushuigou and Baihua in the Guanzizhen formed in paleoislandarc setting in the MiddleLate Ordovician (471～440Ma), while had subduction type (450～456Ma) and collision type (438～400Ma) granitoids magmatism in the Caledonian. Early Paleozoic paleooceancontinent of structural framework in northern margin of West Qinling had come through evolution of plate tectonics from formation ocean basin to subduction of oceanic crust, until continentalcontinental collision orogeny. The overall tectonic evolution be divided into four stages: ① Paleoocean basin initial form stage in the Late Cambrian. ② Ocean basin initial subduction stage in the Early Ordovician. ③ Wholesale subduction and paleoislandarc growth stage in the MiddleLate Ordovician. ④ Continentalcontinental or continentalarc collision orogeny stage in the Silurian.
