Abstract

Abstract

High-Mg diorites occur widely in western Shandong: the Tietonggou and Jinling intrusions are typically representative. The weighted mean 206pb/238U ages from LA-ICPMS zircon U-Pb dating results for early norite-diorite, late pyroxene-diorite from the Tietonggou intrusion and biotite-diorite from the Jinling intrusion are (131. 4±4. 9)Ma(n = 15), (134. 5±2. 3)Ma(n=13), (132. 8±4. 2)Ma(n=12), respectively, implying that they were formed in the Early Cretaceous. The weighted mean ²⁰⁷Pb/²⁰⁶Pb age for round zircons from late pyroxene-diorite from the Tietonggou intrusion is (2 513±54)Ma(n=8), suggesting that the basement of the North China craton should exist in the research area. The high-Mg diorites are characterized by enrichment in Mg^#, Na, and light rare earth elements (LREE). They are poor in heavy rare earth elements (HREE) and high field strength elements (HFSE), being similar to adakite. The occurrence of the mantle peridotite xenoliths and the high-Mg feature for these intrusive rocks imply that their primary magma should be derived from the upper mantle. However, Sr-Nd isolopic compositions (I_sr: 0.704 75 - 0. 707 72; ε_Nd(t) values: -3. 95 to - 13. 30), depletion in HFSE, and the occurrence of the Archean inherited zircons suggest that crustal materials be involved in the derivation of primary magma The compositional difference between the diorites from the Tietonggou and Jinling intrusions could be attributed to magma sources and partial melting degrees. It is considered that the Early Cretaceous high-Mg diorites were formed by the mixed melting of the delaminated lithosphere (lithospheric mande+crust) and asthenosphere, based on their geochemistry, the mantle-derived xenoliths, and the Early Mesozoic lithospheric evolutionary history of the eastern North China craton.
