Thus , the paper focuses on mineralogy , petrology , petrogeochemistry , isotopic chorology , and sr - nd - pb isotopes of the mafic intrusions and dikes in fujian province , se china . in addition , we also discussed the process of the plate subduction , mantle evolution , crust - mantle interaction , lithospheric thinning and extension , and the reaction for crustal extensi on in fujian province , se china . ( 1 ) daiqianshan mafic intrusion is situated along the changle - nanao fault , which intruded in the metamorphic rocks 基于此,本文以中國東南部福建省的基性脈巖、巖體為研究對象,運用系統的礦物學、巖石學、巖石地球化學、同位素地球化學及同位素年代學證據,詳細論述了晚中生代中國東南部板塊俯沖、地幔演化、殼幔相互作用及巖石圈伸展減薄的地球動力學過程,探討了地殼拉張期次在福建省區域構造上的響應。

Therefore , based on the isotopic chorology , petrochemistry , geochemisty and sr , nd , pb isotope , the ph . d dissertation mainly studied some yanshanian mafic dikes , volcanic rocks and alkalic - ultramafic dikes in shandong province 本論文主要從同位素年代學、巖石化學、地球化學和sr ? nd ? pb同位素方面對山東地區燕山期基性脈巖、火山巖和堿性超基性脈巖進行了系統研究。

However , it is unsubstantial for the investigation on chorology and geochemisty , and dissimilar for the research on petrogenesis and tectonic setting 但關于它們的年代學和系統的地球化學研究還比較薄弱,且對其成因和形成的構造環境,仍存在著爭議。
