Abstract There are many felsic dikes in the Lucaogou area of Beishan orogenic belt in the southernmost Central Asian Orogenic Belt (CAOB). In order to understand the regional geological evolution rebuilding, petrology, geochronology and geochemistry analyses of the Lucaogou felsic dikes were performed. The results showed that these dikes have zircon U-Pb age of (248.1±1.8) Ma, indicative of the product of Early Triassic magmatism. The dikes have relatively high SiO2 and low MgO. They also are enriched in LILE (Rb, Ba, Th, U, K) and depleted in HFSE (Nb, Ta, Ti,P), with an significant negative Eu anomaly. These rocks have low Y, Yb contents, with high Sr/Y, La/Yb and relatively low Na2O/K2O ratios, which are similar to the geochemical characteristics of the Yanshanian adakitic rocks from Eastern China, indicating that the felsic dikes are likely to be derived from the partial melting of the thickened lower crust in the post-collisional setting, with pyroxene + garnet + rutile ±amphibole as residual phases.
