| 摘 要： | 通过对河南西峡二郎坪花岗岩体的岩石学、岩石化学、地球化学特征研究，作者认为岩体为岩浆成因，且其源岩为宽坪群的变基性火山岩和变泥砂质岩石。用Ｇ．Ｆａｕｒｅ（１９８６）给出的简单二元混合方程，通过对Ｓｍ－Ｎｄ同位素的计算得出二郎坪岩体由约６４％的变基性火山岩和约３６％的变泥砂质岩石熔融而成。

| Abstract: | By studying the petrological and petrochemical characteristics of Erlangping granite pluton,it is thought that Erlangping granite pluton is magmamorgenic and its source material came from the metamorphous mafic volcanic rock and the metamorphous argillite and psammite of Kuanping group rock.Using the simple binary mixture equation of G.Faure(1986) and calculating the data of Sm Nd isotope,the author concluded that Erlangping rock mass could be formed from 64% metamorphous mafic volcanic rock and 36% metamorphous argillite and psammite. |
