本文对宁芜辉石闪长玢岩的形成提出了一种全新的解释,欢迎大家讨论。
The paper studies the occurence and petrochemical characteristics of Ning-Wu Mesozoic volcanic rocks and considers that the pyroxene diorite porphyry was formed before the overlaid pyroxene an- desite,and it is a high-level intrusion placed near to the surface.This pointview can explain many hanging problems of the origin of Ning-Wu porphyric iron deposit.
