从埃德格山采取大约400个岩石样,作了主要元素和28个徽量元素分析,研究的岩石样品大多数是花岗岩,少量是细晶岩、伟晶岩和长英质岩脉。岩基中主要岩石类型的平均成分相当于花岗闪长岩—钠质花岗岩界线附近的花岗闪长岩,单个样品主要是上述两种岩石类型。大部分铁镁质花岗岩类认为是一种石英闪长岩。在岩基的中心部分,单个深成岩体从野外和化学分析上可以区别,所有深成岩都有
Approximately 400 rock samples were taken from Mount Edgar, and the main elements and 28 elements were analyzed. Most of the rock samples studied are granite and a small amount of pristine, pegmatite and feldspathic dykes. The average composition of the major rock types in the rock mass is equivalent to the granodiorite near the boundary of the granodiorite-sodium granite, and the single sample is mainly composed of the above two types of rocks. Most of the mafic granites are considered to be a type of quartz diorite. In the central part of the rock foundation, a single deep pluton can be distinguished from both the field and chemical analyzes, and all plutons have
