本文探討浙江省燕山期花崗岩11个岩体的岩石比学特征。燕山早期以花崗閃长岩为主,晚期以花崗岩为主。其平均化学成分与戴里数值比較,略偏硷性。文中共收集了113个岩石化学分析资料。用这些資料以查氏和巴尔特方法进行計算,探討在铁鎂、碳酸盐、鋁矽酸盐同化作用下岩石化学成分演变规律。并相应研究了分異作用的化学特征,最后将两者之異同点作了合理比較。本文尚探討了花崗岩中微量元素特征。証明本期花崗岩成矿元素(Cu,Pb,Zn)、稀有及稀土元素含量高。这与华南同期花崗岩有近似之处,就微量元素存在状况,探討了各岩体有关的成矿作用。并对矽卡岩型磁鉄矿、中低溫多金属矿床成矿条件进行了初步探討。
In this paper, the rock characteristics of 11 rock mass of Yanshanian granite in Zhejiang Province are discussed. Early Yanshan granodiorite-based late granite-based. The average chemical composition and Dale value comparison, slightly alkaline. The paper collected a total of 113 rock chemical analysis data. Using these data, the calculation of Chalcot and Barthes method was conducted to investigate the evolution of petrochemical composition under the assimilation of Fe-Mg, carbonate and aluminosilicate. Correspondingly, the chemical characteristics of differentiation were studied. Finally, the differences and similarities between the two were compared reasonably. This article also discusses the characteristics of trace elements in granite. Prove that the granite metallogenic elements (Cu, Pb, Zn), rare and high content of rare earth elements. This is similar to the granites in South China and contemporaneous with the existence of trace elements. The mineralization related to each rock mass is discussed. The metallogenetic conditions of skarn-type magnetite ore and medium-low temperature polymetallic deposits are discussed.
