基性岩脉中的煌斑岩是深部地幔富金源体中金的载体,在时间和空间上都与金矿密切相关,在火成岩中含金量最高(Mc Neil and Kerrich,1986;Rock and Groves,1988)。前人的研究显示,煌斑岩脉中多产出金矿(赖少聪和徐海江,1993;Kerrich and Wyman,1994;Taylor et al.,1994;应汉龙,1996;程小久等,1998;涂
The lamprophyre in the mafic dikes is a carrier of gold in deep mantle-rich gold source bodies and is closely related in time and space to gold deposits, with the highest gold content in igneous rocks (McNeil and Kerrich, 1986; Rock and Groves, 1988). Previous studies have shown that the gold deposits in the lamprophyre are prolific (Lai Shaocong and Xu Haijiang, 1993; Kerrich and Wyman, 1994; Taylor et al., 1994; Ying Hanlong, 1996; Cheng Xiajiu et al., 1998;
