野外地质、岩相学和地球化学研究证实，平潭火成杂岩是高铝玄武质岩浆和花岗质岩浆不同程度机械混合和部分化学混合作用生成的。对这一杂岩体岩石成因的认识，将为我们研究中国东南部晚中生代钙碱碱性省基性岩与酸性岩的时空紧密联系问题提供新的思路。
Investigations of field geology, petrography and geochemistry confirm that Pingtan igneous complex was generated by mechanical mingling and partially by chemical mixing in different degrees of the high-alumina basaltic magma and granitic magma. The understanding of the petrogenesis of this complex would give us a new idea for studying the problems about the closely temporal and spatial association of basic and acidic rocks in the Late Mesozoic calc-al-kaline province in SE-China.
