地幔源区岩性是控制地幔部分熔融过程中微量元素行为的重要因素。近十年来,第一周期过渡族元素(FRTEs,First Row Transition Elements)被广泛应用于地幔源区岩性识别。超基性、基性岩石部分熔融过程中,FRTEs表现为相容到中等不相容,是追踪地幔源区岩性的有力工具(Le Roux et al.,2011)。Humayun et al.(2004)精确测定了夏威夷玄武质熔岩、冰岛苦橄岩以及大洋中脊玄武质玻璃 The lithology of the mantle source area is an important factor in controlling the trace element behavior in the partial melting of the mantle. In the recent ten years, the First Period Transition Elements (FRTEs) have been widely used in the lithology identification of mantle source areas. During the ultrabasic and basic rock melting, FRTEs show a compatible to medium incompatibility and are powerful tools for tracing the lithology of the mantle source (Le Roux et al., 2011). Humayun et al. (2004) accurately measured basaltic lava in Hawaii, picrites in Iceland, and mid-oceanic basaltic basaltic glass
