Gubaoquan dolerite dykes are predominantly intruded into Ordovician-Devonian granodiorites, and a few are interspersed in Early Paleozoic strata. The dykes are divided into two different rock types, including dolerite and sillite. The mainly minerals are plagioclase and pyroxene, with minor amphibole, biotite and some accessory minerals. The results of zircon U-Pb dating yield an age of(285.0±4.7)Ma, indicating the emplacement time of dolerite dykes, which is coeval to the formation age of dolerite dykes in other places of Beishan area. The εNd(t)of Gubaoquan dolerite varies from 6.39 to 6.78, indicating that the parental magma is derived from a depleted mantle source. The whole rock Sr-Nd isotopic simulation suggests that the magma undergoes a 10%-15% of contamination by upper crust materials during emplacement process. The LREE/HREE ratio of dolerite varies from 1.72 to 2.17, and the chondrite-normalized REE pattern displays a flat pattern. The primitive mantle-normalized trace element spider diagram shows obvious negative anomalies of Nb-Ta. The characteristics of rare earth and trace elements are different from Bachu dolerite associated with mantle plume activities in Tarim block, but are similar with Yin’aoxia(east part)and Podong(west part)dolerites in Beishan area. Integrated with the existing research results, it is suggested that Gubaoquan dolerite dykes are formed after the closure of Paleo-Asian ocean, as the result of basaltic magmatism caused by the decompression and partial melting of asthenosphere due to lithosphere delamination and break-off in an extensional environment.
