通过对华北克拉通不同陆核斜长角闪岩类氧同位素组成测试和分析 ,表明 :(ⅰ )来自不同陆核的岩石氧同位素数据所构成的演化线都平行于地月演化线 ,说明这些陆核演化的母体属于太阳系物质 ;(ⅱ )不同陆核的氧同位素组成演化线斜率相近 ,截距不同 ,说明华北克拉通太古宙不同陆核起源于氧同位素组成不均一的古地幔源 .
The oxygen isotopic compositions of different amphiboles in different continental nuclei in North China Craton show that: (i) the evolutionary lines of rock oxygen isotope data from different continental nuclei parallel to the Earth-Moon evolutionary line, indicating that these The precursors of the evolution of the continental nuclei belong to the solar system. (Ii) The evolutionary lines of the oxygen isotope composition of different continental nuclei have similar slopes and different intercepts, indicating that the different Archean continental nuclei in the North China Craton originated from ancient mantle sources with heterogeneous oxygen isotopic composition.
