【摘要】 西秦岭北带与微细浸染型金矿有关的脉岩,空间上与矿化密切伴生,时间上略晚于矿化,成因上脉岩和矿化均与中川花岗岩杂岩体有关,为同一岩浆——构造事件不同阶段的演化伴生产物.论文从岩石学、岩石化学、微量元素、同位素等方面讨论了脉岩的地质特征及其与金矿的关系.更多还原

【Abstract】 The dike rocks related to fine impregnation type of gold deposits in the northern zone of western Qinling, which intrude in postmineralization, were closely associated with mineralization spatially. The dike rocks and gold deposits, both of which have close relation with Zhongchuan granite intrusive complex,are associated outcomes in different evolutionary stages of magma -tectonic event.This paper describes the characteristics of dike rocks. The relationship between the dike rocks and the gold deposits was also discussed, based on petrology,petrochemistry,trace element,stable isotope and so on.更多还原
