基性岩脉中的煌斑岩是深部地幔富金源体中金的载体,煌斑岩(尤其是钙碱性煌斑岩)在时间和空间上都与金矿密切相关,被认为是含金量最高的火成岩,是金矿找矿的重要标志(Mc Neil and Kerrich,1986;Rock and Groves,1988)。因此,对煌斑岩的研究越来越受到重视。前人的研究显示,煌斑岩脉中多产出金矿,例如:在澳大利亚、加拿大、胶东(玲珑,蓬家夼,邓格庄,金青顶)、云南(老王寨、小水井、
The lamprophyre in the mafic dikes is the carrier of gold in the deep mantle-rich gold source. The lamprophyres (especially calc-alkaline lamprophytes) are closely related in time and space to the gold deposits and are considered to be gold-bearing The highest igneous rock is an important symbol of gold prospecting (McNeil and Kerrich, 1986; Rock and Groves, 1988). Therefore, the research on lamprophyre is paid more and more attention. Previous studies show that the gold deposits in the lamprophyres are prolific, for example, in Australia, Canada, Jiaodong (Linglong, Pengjiajie, Denggezhuang, Jinqingding), Yunnan (Laowangzhai,
