Abstract: The intrusive rocks of Baijiazang is located in Minhe County, Qinghai Province, and the geotectonic position is located in the eastern section of Lajishan ophiolis melange belt. Through petrology, petrogeochemistry and isotopic chronology, the intrusive rocks of Baijiazang have been studied in order to determine their time of emplacement and to explore the tectonic environment. The results show that the intrusive rocks in Baijiazang are mainly composed of diorite and quartz diorite. Zircon U-Pb age obtained from diorite and quartz diorite is (472.5±1.9) Ma and (467.3±2.5) Ma, respectively, and they are consistent within the error range. Therefore, it can be judged that the emplacement age of Baijiazang rock is about 470 Ma, which is Middle Ordovician. The geochemical characteristics show that the SiO2 content of the rock mass is 55.67%-59.04%. The value of Na2O/K2O was 3.35-6.14, and w (Na2O) was higher than of w (K2O), showing the characteristics of rich in sodium and poor in potassium. The main body of A/CNK value is between 0.76 and 1.01, belonging to the quasi-aluminum calc-alkaline series rocks. The rare earth partition curve presented a slightly right-leaning curve, where light rare earth elements were relatively weakly enriched ((La/Yb)N=2.51-4.57), and light and heavy rare earth elements were weakly fractionated internally. The rocks were obviously enriched with large ion lipophilic elements Rb, Ba and active incompatible elements Th and U, while relatively deficient with high-field strength elements Nb, Ta, P, Ti, etc. Environmental discrimination shows that it has the characteristics of island-arc granite. The above characteristics indicate that the intrusive rocks in Baijiazang were produced at the subduction stage of the Lajishan ocean.

Key words: geochemistry, zircon U-Pb age, petrogenesis, subduction, Middle Ordovician, Lajishan
